Impossible to compile on Alpine Linux(musl libc)

[illiliti]

-DMEMORY_ALLOCATOR=standard should be specified by default for musl libc because it doesn't support custom memory allocators

Non-portable functions should be removed or replaced with alternatives(e.g libexecinfo)

• src/xrCore/FS_internal.h src/xrCore/LocatorAPI.cpp
  • sys_errlist glibcism
• src/xrCore/xrDebug.cpp
  • execinfo.h glibcism
• src/xrCore/_math.cpp
  • fpu_control.h glibcism

Cmake generates invalid <build directory>/src/xrGame/cotire/xrGame_C_prefix.c with missing includes

#include <string.h>
#include <stddef.h>
#include <stdlib.h>

Cmake should search include path for directfb in /usr/include/directfb too, not just /usr/include

i solved these issues by removing directfb and fortify-headers packages

i also found missing include #include <signal.h> in src/xrCore/xrDebug.cpp

@illiliti, can you test if the game is playable with musl libc?

Also, just a small comment:

It's SDL2 that tries to include directfb header... I fixed compilation errors by just removing some SDL2 headers from compilation.

I'm not sure if this is our issue and, maybe, it should be submitted to SDL2 repository.

Thanks for working on this!

Good question! I don't use alpine anymore(but i still use musl!) since I moved on to a more minimal system a long time ago. Building some xray-16 dependencies might be quite challenging there... I'll try to look into it, but can't promise anything
