Cannot compile under Archlinux.

[sudodebian]

Hello i'm trying to compile SDL-Mixer-X for some other thing i need to compile since i don't have this library installed.

But when i'm trying to configure with cmake `CMake Error in /home/sudo64/Documents/kektech/deps/SDL_mixer_ext/compile_tests/CMakeFiles/CMakeTmp/CMakeLists.txt: Found relative path while evaluating include directories of "cmTC_b128d":

"OPNMIDI_LIBRARY-NOTFOUND"

CMake Error at cmake/CppNeedCheck.cmake:10 (try_compile): Failed to generate test project build system. Call Stack (most recent call first): src/codecs/music_midi_opn.cmake:13 (cpp_needed) CMakeLists.txt:246 (include) ` (It also asked for adn, but i had already the library installed.) For some reason, even without the -DMIXER_ENABLE_GPL=ON argument, it seems to try to configure and link those libraries as well.

Any idea on how to fix this ? Thanks.

Do you have a C++ compiler installed ever? What version of CMake you do use? Soulds like it fails to run the try_compile() function :thinking:

I do have a compiler, gcc to be precise.

I'm using CMake version 3.27.7-2

Do you have g++ too? Anyway, I guess, if g++ would absent, the configure would just fail because it can't find C++ compiler, even before. Anyway, I got another idea why it would fail, possibly something related to file system. But I can't guess what. Could you upload a full log of CMake?

I'm using CMake version 3.27.7-2

Lemme try here... At me is 3.27.1 and it works just fine, shouldn't be much difference.

Full log, like what the cmake commands outputs when i'm trying to configure it ? (sorry for my lack of understanding, i'm pretty new to Cmake.)

Yes, just the full CMake's output since when you ran the command. Just copy output of terminal into text file and put here.

Alright.

`CMake Warning: No source or binary directory provided. Both will be assumed to be the same as the current working directory, but note that this warning will become a fatal error in future CMake releases.

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required): Compatibility with CMake < 3.5 will be removed from a future version of CMake.

Update the VERSION argument value or use a ... suffix to tell CMake that the project does not need compatibility with older versions.

Oh!!!! Seems you went wrong. So, how to CORRECTLY configure CMake projects in general:

mkdir build
cd build
cmake ..

And, never run cmake . at the same directory as project, this will lead a total unworking mess.

Tried this, gives me the same result.

Weird... Anyway, try to perform the git checkout . and then, re-run the thing. Seems because of your first attempt, some files got been broken.

Yup ! you were right. for some reason downloading this and extracting with GNOME's file manager corrupts it a little bit. Git cloning it seems to have fixed the issue entirely. I guess i'll have to install file-roller next time i ever want to extract something from github. Thanks ! It seems to have compiled just fine too !

[Wohlstand]

Glad the thing works! Have a good time!
