--- NVIDIA announces PhysX SDK 4.0, open-sources 3.4 under modified BSD license ---
NVIDIA has announced a new version, 4.0, of PhysX, their physics simulation engine.
Its new features include:
- A "Temporal Gauss-Seidel Solver (TGS)", an algorithm used in this SDK to make things such as robots, character arms, etc. more robust to move around. NVIDIA demonstrates this in the video by making their old version of PhysX, 3.4, seem like an unpredictable mess, the robot demonstrating that version smashing a game of chess.
- New filtering rules for supposedly easier scalability in scenes containing lots of both moving and static objects.
- Faster queries in scenes with actors that have a lot of shapes attached to them, improving performance.
- PhysX can now be more easily used with Cmake-based projects.
In essence, better control over scenes and actors as well as performance improvements are what's new.
Furthermore, NVIDIA has released PhysX version 3.4 under the 3-Clause-BSD-license, except for game console platforms.
As NVIDIA will release the new version on December 20th, it will also be released under the same modified BSD license as PhysX 3.4 is now.
What are your thoughts on NVIDIA making a big move towards the open-source community by releasing PhysX under the BSD license? Feel free to let us know in the comments!
Some days ago I finished "Ray tracing in a weekend" (Peter Shirley) and I'm learning a lot :D
In the new year I will start with "Ray tracing the next week", but there are still some things I want to tackle before that (improve code quality, optimize... it's my first project that is bigger than a codeforces problem solution, a part from the projects at work).
Any sources of wisdom and recommendations are welcome!!9
I'm working on a programming language with a "bytecode" interpreter and a compiler that translates source code to said bytecode and... it sort of actually works!
I want to recreate an Erlang-style environment, currently you can write functions, call C++ functions via wrappers, have immutable-only values, and it has no explicit control structure apart from statement sequencing and the if-expression because I want to make it as functional as possible. Next thing on the list is to add a green threads implementation and ability to spawn and send messages to processes.
Still a WIP and heck even design-in-progress.
Now for the rant:
I'm using CMake for building C++ (interpreter) and Stack for Haskell (compiler) and I've been trying to get them to talk to each other for hours because I want CMake to manage the Stack build too and shove all the executables into one place. CMake documentation is weird and Stack isn't too helpful either, so I guess I'll just spend another few hours trying to get Stack to fuckin reveal its build directory to CMake and/or build to a given directory. Ugh.8
I kind of feel like I invested 2.5 years of my life trying to run away from being a hamster, and here I am in my PhD back in the hamster spot.
The moment I finish compiling some not-os-compatible package, I get a new one to tame. A day after perfecting a sensor integration, another sensor is thrown at me. I am the one who calibrate and tunes the MoCap system, including manufacturing the markers and ordering part. I make sure the robot is functional, from software to battery replacement.
I need to crawl on floors to collect data, while the rest of the lab uses public datasets.
I optimize C++ code, and then get asked to write unit tests and use a CI, while the rest of the lab just writes some subpar Python.
They are doing research and I am doing Cinderella work.
I shouldn't be punished because I get shit done, whether it 3D modeling, CMake voodoo or low-level programming.
Instead of encouraging other lab mates to develop skills, everything is thrown at me. Fuck that shit.6
Why is starting a C++ project so overly complicated and annoying?!
So many different compilers. So many ways to organize the files. So many inconsistencies between Linux and Windows. So many outdated/lacking tutorials. So many small problems.
Why is there almost no good C++ IDEs? Why is Visual Studio so bizarre? Why are the CMake official tutorials literally wrong? Why can't we have a standard way to share binaries? Why can't we have a standard way to structure project folders? Why is the linker so annoying to use?
Don't get me wrong, I quite like the language and I love how fast it is (one of the main reasons I decided to use it for my project, which is a game almost comparable to Factorio)... But why is simply starting to write code such a hassle?
I've been programming in Java for years and oh god I miss it so much. JARs are amazing. Packages are amazing. The JDK is amazing. Everything is standardized, even variable names.
I'm so tempted to make this game in Java...
But I can't. I would have a garbage collector in the way of its performance...12
This bonehead wants to delete your C++ code. He obviously means that to use this for out-of-source builds, but still pretty dumb and easy to mess up.2
In 15+ years of full time work as a C++ software engineer there is one tool that I always hated: CMAKE. What a fucking pile of shit, seriously, every time there is project that uses it I simply cannot build said project with one click. In all these 15 years working in different companies the only reason people speak about cmake is to avoid adding source files to multiple projects (VS, XCode, Android).
I'm not some kind of newbie: I've make cmake projects myself, I've build hundrends of projects that use cmake and I even contributed fixes to their code. I still believe that cmake is garbage that should stop to exist.9
WHAT THE FUCK?
CMAKE you pathetic collection of loosely bundled scripts written in a shitty macro language!
WHY? WHY? WHY?
WHY DO YOU REFUSE TO OUT OF SOURCE BUILD?
IT WORKED FINE LIKE 2 SECONDS AGO! I HATE YOU WITH THE FIRE OF A THOUSAND STARS!2
I can't take a (C++) project seriously if it is using Visual Studio's build system instead of autotools, CMake or even just a Makefile.8
Visual Studio 2022 compiles our internal c++ cmake project as a mix of x86 and x86_64 binaries, then fails to link.
VS 2019 correctly compiles everything as x86_64.
No idea why. And, obviously, it's not a documented problem.6
CMAKE, YOU PILE OF SCRIPTING SHIT!
WHY THE FUCK CAN I NOT CHANGE MY BUILD DIRECTORY? I HAVE WASTED AN HOUR ON THIS UNBEARABLE SHITWEASEL OF AN EXCUSE FOR A BUILD SYSTEM!!!!
STOP SHITTING YOUR STUPID CACHE FILES INTO MY SOURCE FOLDER!!! AAAAAHHH!11
New team, same discussions...
* Why should we use cmake? It is way better to add visual studio project files to the repository and allow everyone to mess around in the compiler setting dialogs. Nobody needs cmake if not targeting multiple platforms!
* clang-format? What kind of black magic is this? It is way better to manually try to stick with each source file's existing formatting - regardless of how messed up it is - and manually check that from time to time!
* Why should we use the latest visual studio 2019 compiler, if 2017 and 2015 do just fine? This way we can save license fees!
Just to mention a few highlights...13
After many painful hours of fixing cmake errors, I've managed to successfully build 2 large C/C++ projects in a week. That shit hardens you.3
I encountered every possible bug setting an Ubuntu VM environment to test my engine. I manually created all the eclipse projects and it's now available on the repo - it compiles and runs.
Suggestions for a good CMake guide?4
I fucking hate the process of setting up IDEs and compilers! All the build files, cmake files, tasks, all that shit.
I undrerstand it's integral part of coding, but fuck, why does it always take so long to set up a stupid project. Just let me start coding ffs.
Sometimes I get so frustrated that I rather write a bash script or run the compiler commands in the shell instead of going through the hassle of setting all this up.2
Translating win32 calls to whatever the hell there is in Unix and Unix-like OSes (well, most of them) in order to port a certain game net code library and dear god why did I volunteer myself for this task
At least pevents is there to help, but too bad cmake doesn’t want to compile it with the flag I need (“-DWFMO”) in order to make the “WaitForMultipleEvents” method to work at all. Instead no matter what options I give it on the command line or how I tell VS Code to do it, it seems to give me the finger to my fucking face.
Doing it for games on the cooler OSes... doing it for the community... come on...2
Well, I really have nothing to rant about these days 😅
What I do have is a request for feedback on a project’s video, m working on the project and will release it open source once it works decently well, and most of all, when the code doesn’t look so atrociously bad 😅😅
It is basically a C/C++ package and project manager.
It can create, build, and run projects which u make, and add library flags and include directories automatically if that library exists in its package list.
It also contains package (=library) manager which can, as of now, install, uninstall, and fetch info of any package should it exist in the package list.
I will be adding package upgrading in the future, although package list updates can be performed.
Also, right now it can only build binary projects. I’ll soon be working to enable creation of library ( static/dynamic ) projects as well.
Finally, it allows for building of packages using CMake or configure, but uses a custom format to build projects.
Here is a video of building a project and installing libcurl on system:
Thanks a lot ☺️😊1
So let's say you spent over a day trying to clone WebKit using git but it failed every single time. Because the WebKit repo is HUGE (at least 7GB of worthless bloated refs), your connection is unstable, and git doesn't resume.
Then you discover you can solve the issue by simply cloning it via SVN in your cmake script.
Then you hit build, and forget that you had `-j 8` set in your IDE settings.
Then your computer freezes when it tries to compile 8 of WebKit's "UnifiedSourceXXX.cpp" files at a time, and all your 16GB of RAM get obliterated.
What the fuck, universe?1
Mhhh. CMake scripting. Always fun. I can barely describe how enfuriating it is dealing with this. Literally shaking.2
I wanted to install this new software in our cluster but it didn't have Cmake on it, so I scp Cmake source files and then I started looking for a CMakeLists.txt file for compile it when I suddenly realized what I wanted to accomplish in the first place 😅1
C++ development will be my end.
The absolutely unreadable errors, the overly convoluted macros set up in the project, the cmake build system.... The absolutely unnecessary separation into cpp and header files...
Trying to start doing stuff with C but CMake is very confusing and I can't find anything solid (and easy to read) about setting it up and including depends and what not. We are totally spoiled in Java with tools such as Gradle or Maven.3
I have personally struggled a little with CMake always. I usually have to take help from some senior dev. Today I was able to figure something out on my own so this is an achievement story. Think I should treat myself with a book3
I'm working in a complex CMake/C++14 project.
Many libraries uses EASTL as STL replacement, works and compiles flawlessly.
Have to use Qt5 for an application which uses the libraries.
The EASTL Library fucking collapses
Compile fails, 1k of syntax errors somehow.
After hours trying to figure out without alterating the EASTL library (i don't want to maintain custom versions of 3rd party libraries, an complete burden to maintaining updated)
Remove all reference of Qt5 from the code and the build system.
It fucking compiles.
Isolate an minimal build which only uses CMake, EASTL and Hello World in Qt5.
1k of syntax errors again.
Spend hours trying to fix it, no avail, still fucking 1k syntax errors.
I'm past beyond of the project development where ALL the big libraries of the project uses EASTL extensively.
One day C++ will drive me into the depths of madness.2
Fuck. I just want to fucking use OpenCV on CLion on Windows. Why the fuck do I need twenty fucking PhD's in quantum rocket science to set up a simple project with Cmake?
During the time I just wasted trying to get the correct library to link properly, I could have rewritten all of Tesla's fucking CV functionality from scratch, but instead here I am spending literal fucking hours googling why the fuck does 'recursive_mutex' not name a fucking type in namespace 'std' on mingw.
Fuck C++ I'm going back to C# where I can literally install OpenCV and all of its fucking dependencies from nuget with ***ONE*** fucking click.6
The easiest way to fuck yourself and ruthlessly waste your night away,
Using Boost sources, CMake and Visual Studio together.2
Holy shiiittttt I finally got 64bit NASM working on windows with cmake. Cmake documentation is fkn bad man.
I’ve got a c++ file that calls a procedure in an assembly file that calls win32 APIs to show dialogs and other cool shit. Compiling was working fine, linking turned out to be a bit of a pain in the ass, but figuring out how to enable NASM in cmake was a nightmare. Why is the cmake docs so horrific 🥺1
"Configuring incomplete, errors occurred!" Ok, I get that. But would it kill you to tell me what errors? If you behave like an asshole, I'll hate you as well!
Gotta love it when CMake manages to change the way it handles GLEW in the latest build and breaks the QT moc inclusion directive in the previous. I absolutely detest the current state of cross platform build tools and environments. The amount of ffing time wasted on this crap is just beyond me.2
I just can't get my head around it. How could a "language" like cmake become so widely used and popular? Let alone be the horrible syntax or the documentation which is an insult to anyone who is trying to read it.
I mean seriously??: " function_xyz( PARAM1 PARAM2 PARAM3) : for this use case A pass the keyword A and the words X Y Z, for use case B pass the keyword B and the words A B C you can also add the keyword D simply to increase the number of possible behaviours this stupid function can have."
But yeah i get it, it's free its cross platform and so on.
But how can after version 10000000.1, after adding dozens of "macros or functions" the most simplest and straight forward use case without any fucking thirdparties be so fucking difficult to implement.
And why are there for any use case 50 different ways of doing it? instead of one simple way?
Really, I just don't get it.4
Yo I heard you like compiling C/Cpp so we make you compile and link each individual file so you need a makefile for compiling everything. But that shit still gets to annoying to maintain so you make the make files with cmake. Just so you can compile a library basically at all.
And dont get me started on autoconf and random configure scripts you have to run before you actually configure shit.
Can we make compiling a regualr program any more difficult so that we need a whole ass A4 page of documentation just to end up with a binary of something?15
Dear Kubuntu 20.04
You're not a programming language but I felt that you fit here in this wkRant so people can see how shitty you became.
It's about 6:27am CET, and you wasted my night, you used to be as simple as sudo apt-get install, now you're mostly PPA first or worse, make. You killed make now we use cmake. We are now looking for debs, which is a pain since you end up in an index site without download here. And the debs now don't work. Missing dependencies. You killed core libraries saying they are now incompatible or obsolete.
All I want is my god damn cli visualiser and osdlyrics back!!9
Classmate got me today to write cmake.
I mean after the 2 years of editing it in android repos to fix shit i hated it.
But i must say its pretty good tool.
Also i may have written it in VIM.
Dont worry NANO team. I wont leave you. Im still proud user of NANO.4
Note to self: Next time remember to clean build when CMake is throwing an error, before you start whining to the library support team.2
Let me start this off by stating I'm a Java dev, and a noob with C++.
Thought it'd be cool to learn some OpenCL, since I want to do some maths stuff and why not learn something new.
So I sat down, installed Nvidia proprietary drivers, broke my x-org server, purged, reinstalled, rebooted and after a while I got stuff sorted out.
Then on to my IDE. I use CLion and it uses Cmake. C++ noob knows shit about Cmake, so struggle for two hours trying to figure out wtf is going on with the OpenCL libs and why they're only partially detected. Fml.
Finally, everything is configured and I'm set. I start working on a Hello World program using OpenCL. Finish it in 20 mins, all good. No output. Do some googling, check my program a million times. Nothing wrong here. Check the kernel, everything as in the tutorial.
I start checking error codes after a while reported by OpenCL (which I had no clue was a thing) and I get some code saying the program was not created properly (to run the kernel). No fucking clue what's up with that. Google around, find another tutorial, rewrite my code in case I'm using outdated code or something. Nothing.
Fast forward an hour, I find out that OpenCL has logs! So I grab some code from the website I found it on, and voila, I finally get some info on what's going on.
Get a load of this bs.
In the kernel file, so that OpenCL knows that it's a function to run, you have to put __kernel. But in all the places I read, it said to put it as _kernel.
Add the underscore, compile, run and everything is perfect.
Then I tried just putting 'kernel'. Also compiles and runs fine.
Two hours hours and my program was fixed by adding an underscore. IF ONLY C++ GAVE AN INDICATION OF WHAT BLEW UP INSTEAD OF SITTING BACK AND BEING LIKE "oh wow man feels bad, work some magic and try again" THEN THIS WOULD NOT HAVE TAKEN SO LONG.
Then again, it was OpenCL that was being shitty with its styling enforcement or whatever the hell the underscore business is. But screw it. C++ eats shit too for this. Sure, maybe Java babies you by giving you the exact error and position that the error took place at. But at least that way you don't waste hours of your life chasing invisible bugs 😠😠
I'm going to eat some food... Too much energy was consumed fighting the system... Then I'll get back to OpenCL because 😇 but that doesn't make it less bs.1
I have been writing c++ for a long time and I have gotten away with using my own buildscripts and nothing more.
Just started using cmake for a library. What the absolute fuck is this. I have never felt this out of depth in a long time.
CUDA is a fucking bitch when it comes to configure projects
Creating my first CUDA project it yelled at me it doesn't support my current gcc version, ended up with me yelling back "OY SHUTUP" and slapping some flag for it to use clang instead — basically what it advised but I didn't listen first. Fine now.
Working on this project on another fresh environment, and now it doesn't detect anything and dumbly tries to reload my CMake project with the LATEST installed gcc when I already told it to use version 8 TWICE. First by setting up a toolchain with compilers pointing to this specific version and second by passing the -DMAKE_C_COMPILER pointing to it again. Still this stubborn piece of shit tries with latest everytime.
The most applauded solution was to use update-alternatives to make gcc point to the version I want CUDA to use. Thank you genius, but what if I don't want to use a deprecated gcc version with normal Cxx projects ?
And cherry on the top of this bullshit, I'm fixing this dumb configuration issue (can't stress enough how much I hate this shit) to be able to fix an EVEN MORE annoying issue with CUDA being a bitch AGAIN and not letting me use std functions where I'm allowed to
Fuck CUDA. Fuck CMake. Fuck C. Fuck everything3
I'm always wondering what was there in people minds when Cmake build system was invented.. I mean, I know drugs were super strong in the '80s, but this is ridiculous..20
Detecting platform in cmake (which I hate).
WHY do you display "armv71", yet can't match the string "armv71"???!?
I'll need to post my cmake lists and cli results on stackoverflow.
OK, last try, I'll copy and paste from the terminal into my file.
Ooooh! You weren't saying "armv71"! You were saying "armv7l"! 😥
(And my font does make a difference between l and 1)1
Brain : Hey, there's this task that needs to be done

Seriously though, if you guys could suggest some good cmake tutorials ( I'm using VSCode and GCC 8.1.0 for compilation ) - that'd be swell :)
Writing cross compilation build scripts make me feel like I'm constructing a log cabin from scratch, on the moon, without a suit, and no trees.
CMake toolchains are a joke. I've thrown them out entirely at this point and am writing custom detection logic for the different cross compilation combinations.
On that note, Microsoft's layout for their development kit is an absolute NIGHTMARE. Get your shit together, Microsoft.
Going to be a VERY long day.3
WHY is cmake such a total shitstain?
Nothing about it works. literally nothing. I can't even make it run a script and do probably the single most fundamental notion of what it means to run a script, which is display its fucking output.12
I would appreciate if the language server wouldn't crash constantly, it's getting rather annoying.
Why is it that most C(++) tooling I have used feels like a half assed barely working project?3
I overheard this mid level dev discussing a new task with a senior dev. They're discussing compile error in cmake. I realized that the mid level dev asked so many basic stuff that are easily google-able. Mind you, our codebase is cmake based, how come she didn't know even the basics and yet survive in our company for years?
I felt bad for the senior dev, as I knew he's busy with his work. He couldn't do his job because he had to do hand-holding with this dev.
My biggest mistake is often trying to solve things by myself which will take hours instead of just asking a senior. But asking other dev for every little things are also annoying. Why can't you just google shit up or RTFM?1
For fucks sake Windows. Why can't you just fucking have a sane terminal without fucking with everything.
Installing and using MinGW and CMake is enough of a pain when in a slow VM.
Does curses even work with color in Windows!? The best I've gotten is a shade of grey, and white, and I can't even get the grey back!
So I did some testing with WebAssembly to see how it works in the most recent version and without Emscripten. I installed CMake and Visual Studio Community 2015 and compiled Binaryen, LLVM and Clang for a few hours (had to do it multiple times because I used the wrong version and forgot a compile flag), ended up with over 10 GB less free space on my laptop.
All that to compile a < 1kb C file to < 1kb WASM code.
At least it works for now and can natively run in (some) browsers.2
Today, I decided to learn build a c++ project using cmake. Since I've never done a big project in C++ I have no experience with these stuff.
Couple of hours for researching and trying to understand how that thing works, how to specify things, this and that. Wrote a small program for testing.
Everything was fine. Makefile was generated and program was worked.
Then.... Somehow, sublime text started to give me error messages like, 'the header file you included is not found.' I hit the makefile again, the built was successfull... I know that, need to add -I to compiler flag so that it can find the files. But in sublime text constantly refuses my 'possible' solutions.
Even ycm in vim does this. They expected me to write includes like '../thispkcg/include/header.h'
Where did i go wrong ..............
Btw it works like a charm in cLion I don't know why..2
Waiting on people to answer and on software to finish running ... again.
I've started viewing CMake tutorials on YT, played that interactive git 'game', read some SO topics and archWiki entries.
Just struggling with concentration and getting myself to wanting to concentrate.
Oh and I'm almost finished with XKCD
Any tips how to spend waiting time useful but interesting/catching?7
Why is it that every time I want to make some dead simple script with Python it turns into the utmost awful programming experience?
Ah no you see you have to install this dependency but even if pip doesn't give you an error your script will still crash on import and vomit up some ugly back trace that doesn't tell you anything.
And then some retarded sub sub dependency wants to run on Python 2 and that has its entire own shithole of dependency hell.
And then for some unknown reason the Python installation wasn't compiled with zlib and some library wants it so you either you compile the entire thing yourself or idk go fuck yourself?
Why is this hot mess of a language still in use? I dont get it, it's easier to set up a cmake project with C++ for gods sake.4
Why CMake is a steaming pile of dogshit
- Doesn't echo the command lines it is running making it hard to figure out what it is doing
- Dumps a bunch of crap all ovey my directory structure. And I thought NPM was bad
- Generates 'Makefiles' but only kinda uses Make? (I think, its confusing) WTF
At this rate I wish I could use just bash scripts. At least I could figure out why a simple thing like why my compilation fails to locate an include file even though Is is clearly specified in include_dirs() directive.
Get phucked, Cmake9
I fucking cannot stand CMake. I hate this stupid fucking piece of software. I've been trying for 3 fucking days to get SDL2 to link just once and I cannot. It doesn't work in the slightest.
Every time I look for help I find a Stack Overflow post from 5 years ago about someone having the exact same problem and all of the responses are "This function is deprecated, use this instead"
THAT DOESNT SOLVE MY FUCKING ISSUE
WHY DOES CMAKE DEPRECATE THINGS EVERY 1.5 YEARS
THIS ACTUALLY MAKES ME WANT TO SWITCH TO INTERPRETED LANGUAGES I CANNOT STAND BUILD SYSTEMS
SURELY IT CANT BE THAT HARD
WE HAVE OPERATING SYSTEMS, AERODYNAMIC SIMULATIONS, AND A GLOBAL COMMUNICATIONS NETWORK BUT WE CANT FUCKING PASS COMMANDS TO GCC PROPERLY?????6
Often when i see the annoying as hell t debug exceptionless let’s just bomb entirely but blazing fastness of c and c++ I feel like a nettard
I use c# for its immutable strings clean syntax and beautiful class markers that are redundant compared to c++ but ensure you tell after adding 1000 methods and total lack of all special characters to indicate reference and derreference and pretty lambda syntax... sure it’s lib poor but I get shit done goddamn it and can read my own code later
So why do I feel empty inside every time i run a ./configure and make under Linux like I’m missing some secret party where neat things are being done and want to sob like I do now
I am not a dotnettard even though 5.0 is an abomination in the eyes of man and god ! Even though Microsoft cooks up overcomplex framework technologies that make a wonderful language underused and make us all look like idiots that they then abandon into the scrap heap! We can’t help Linux users haven’t discovered how much nicer c# is and decided to implement it on their own and port their horrible undocumented ansi c bullshit can we ???? Oh god I feel
So hollow inside and betrayed ! Curse
You gates curse youuuu! Curse you for metro direct3d xna wpf then false promises of core ! May you have a special place in hell reserved for you and your cheap wallpaper shifting monitor paintings and a pool speaker that playeth not but bee jees and ac dc forever and ever amen !
Speaking of which do any c/c++ ides have anything that even begins to rival intellisense on Linux and don’t use some weird ass build system
Like cmake as their default ?
Oh sweet memories of time a while back when I already wrote this and still wasn’t getting then tail I deserved
If you're creating an AUR pakage
Why the fuck are you not referencing every dependency?
And it isn't even some obscure library or anything. It's fucking CMake.3
Statically linking to qt5 is quickly driving me fucking insane.
I've a list of unresolved dependencies during linking longer than a really long fucking list. Ugh.
Cmake, why can't you save me?
Think I'll just go back to dynamic and build on each needed system.1
I'm all for diversity in Linux, I like that there's multiple organizations, flavors, etc., but geez, troubleshooting a huge CMake project that breaks on Fedora and not on Ubuntu because of the way Python2.7 is installed is a real pain. :(
Just wasted a day trying get Robot Operating System working.
Absolute rubbish software. Broken Gentoo Repos, Required packages that don't exist, failing to install cmake files to find the crap it installed, etc.
I already have every library this trash provides but I'm forced to go through it since a newb PHD wrote an image segmentation algorithm which should work just find with OpenCV/PointCloud/Cmake but NO he had to go put it in ROS and ruin my day.1
Is Cmake really worthwhile ? Like, I see the point of autotools, and it seems pretty worthwhile, but why make something you have to hand configure from the looks of it with a vast array of tags you'll use maybe once per project ?
Is there a frontend maybe for it ? I mean I know the concept they state but it hasn't seemed to work very well the last number of projects I tried to build using it, on windows. On linux everything works LOL But if the point is cross platform building whats the deal ?10
CMake with CLion on Windows is driving me crazy, I can't make it work even if I follow the guides :/
There is some better automation tools(for mouse/GUIs users) where I can setup my dependencies in a more straightforward way rather than learning/trying-to-understand this scripts?
What part of cmake generates the link.txt files for gnu make builds ?
The project I'm building right now is consistently skipping adding -ltiff in random links, yet there seems to be no obvious error in the environment this should be happening, however it might be somewhere in the configuration with which I am not familiar.
Is anyone familiar ?6
Any good "CMake for newbies/dummies" guide that doesn't require 2 hours of readikg or watching to be able to create a VS solution using CMake for a simple project??1
So when installing an rpm there is a file collision check. When you add a file to an rpm package with cmake / cpack it unfortunately adds parent directories your file goes into, which will give you conflicts with other packages. But well you have that beautiful feature to exclude directories from being added:
Now somehow it failed. Turned out it would not work if my path ended with a backslash. Brush my banana! Like "/etc/sysctl.d" is a different animal than "/etc/systclt.d/". - But at least that's nothing against the strangeness of the "mv" command in those respects.
So a while ago I was complaining that tonnes of tutorials ignore CLI or alternative build methods like cmake or meson.
Was having trouble getting glew to link statically... Well only months fucking later do I realise that all I needed to do was add -DGLEW_STATIC to my fucking compiler arguments...
Why is past me such a fucking idiot!
Another hours wasted on debugging, on what I hate most about programming: strings!
Don't get me started on C-strings, this abomination from hell. Inefficient, error prone. Memory corruption through off by one errors, BSOD by out of bound access, seen it all. No, it's strings in general. Just untyped junk of data, undocumented formats. Everything has to be parsed back and forth. And this is not limited to our stupid stupid code base, as I read about the security issues of using innerHTML or having to fight CMake again.
So back to the issue this rant is about. CMake like other scripting languages as bash have their peculiarities when dealing with the enemy (i.e. strings), e.g. all the escaping. The thing I fought against was getting CMake's fixup_bundle work on macOS. It was a bit pesky to debug. But in the end it turned out that my file path had one "//" instead of an "/" and the path comparison just did a string comparison without path normalization.
Stop giving us enough string to hang ourselves!12
Me a basic idiot of a beginner decided to finally try using C or C++, for something small just for fun
So why don't I still understand shit or even do shit with it, even though there is a whole community worth of ideas to try with C or C++
Dart is nice and all but after learning it, C and C++ look like some unwrapped Dart, JS and JAVA and you are to manually to the stuff npm, dart pub and Gradle do for you with Cmake, Meson and Ninja3
is there a fucking utility that will flat out list all installed libraries on a linux system and if cmake and/or pkg-config can find them ???17
So I was building opencv some time back.
Nice enough package, like most python linked packages I'm finding though I know you can use it via c and its meant to be but why would you want to ? .. it contains a whole bunch of half finished crap that is actually useful in part including the capacity to tear apart video files and manipulate frames one at a time and then rewrite them back to a file. about the only lib that's easy to use that I saw that does that. hell I can even compose my own video frames. also the only other lib I saw that does that thus far.
I post a bug, because of FUCKING CMAKE NOT WORKING. not conforming with the well thought out build environment that most GNU style c packages use.
you know like when you need an upstream source package to build the code, or a downgraded package to build the code and don't want to fuck up your host environment so you have to specify a bunch of lib paths and the like so that ld and gcc work correctly etc etc etc from your custom build location and so you can later use these same values to find the compiled lib and build software against it.
fucker closes my ticket saying i hijacked the c environment................
its because cmake sucks.
they're using and i don't know why a module specifically written to find libtiff.
specifically written but doesn't find the only source on my system that provides tiff which my env variables point directly to !!!!
lazy fucking cocksuckers !
I want to code a solution this issue.
something that translates ac files and am files and cmakelists into something intelligent and easy to follow that doesn't sacrifice the flexibility of make and gnu shit and unfucks cmake based projects !7
What is the meson build system and why did you need to break your cmake files in order to support it -_-
