Dear Sir/Madam,
I encountered the below error message from SDL_Error() when running the below command
SDL_setenv("SDL_AUDIODRIVER", "alsa", 0);
SDL_setenv("SDL_AUDIODEV", "pulse", 0);
if (SDL_Init(SDL_INIT_VIDEO | SDL_INIT_AUDIO | SDL_INIT_TIMER | SDL_INIT_GAMECONTROLLER) != 0) {
SDL_Error : Failed loading libasound.a: /home/nkl/.conan/data/libalsa/1.2.5.1///package/d48130e0dd76369b1338deb3b2372c5a649f9f2d/lib/liba
Seems like the path had been truncated. Full path shall be /home/nkl/.conan/data/libalsa/1.2.5.1///package/d48130e0dd76369b1338deb3b2372c5a649f9f2d/lib/libasound.a
How do I check where did the issue arise? Eg cmake, sdl, conan etc
Thank You in advance
FYI : I am using sdl/2.0.20 package in conan center

FYI, I had compiled SDL myself and replaced the conan .a files with my copies and the error goes away. Will investigate more after managed to get ffmpeg (using ffplay.c codes) to work in my program.
Confirmed that issues is with conan SDL libraries
Managed to get ffmpeg to link successfully and using the ffplay.c as my main. It can play mp3 successfully when using own compiled SDL… But when use conan SDL, will hit error.
