cxong commented 3 months ago

The crash appears to come from SDL mixer; more help is needed as I don't have Manjaro

kloon15 commented 3 months ago

How could i repro this in a test code to file it against SDL mixer?

cxong commented 3 months ago

I don't know if this is an SDL mixer bug; it would be best to repro this problem in C-Dogs SDL in a debugger and examine the context to get more clues e.g. what file was it trying to load

RobLoach commented 3 months ago

If it helps, it looks like it's compiled with shared libraries? Compiling via static may fix some compatibility issues across different version. Here's what I'm getting on the 2.0 Linux release build on Ubuntu Mint.

If it helps, it looks like it's compiled with shared libraries? Compiling via static may fix some compatibility issues across different version. Here's what I'm getting on the 2.0 Linux release build on Ubuntu Mint.

I compiled it from source myself so thats a different issue altogether.

TL;DR: Maybe sdl2_mixer package in arch official repository has some error. Compile your own sdl2_mixer and link to it

I met the same error on archlinux

my SDL2_mixer comes from arch official repository, and I install it by sudo pacman -S sdl2_mixer

I cloned SDL2_mixer source code from github and compiled it, then I edited CMakeLists.txt from https://github.com/cxong/cdogs-sdl/blob/fa7410e5976e669d185e7fb6060b3e1d9d1360a0/CMakeLists.txt#L72 to

+ find_package(SDL2_mixer REQUIRED PATHS /home/arch/src/SDL_mixer/usr/lib/cmake)

/home/arch/src/SDL_mixer/usr is the install prefix of SDL2_mixer that I compiled from source

After that the program works.

The crash is introduced by compiling sdl2-mixer with ogg-vorbis instead of ogg-stb which is the default on arch based distros. So confirmed not a cdogs related issue.
