MSYS2 - libSDL2main.a(SDL_windows_main.c.obj):(.text+0x17a): undefined reference to `SDL_main'

[shoober420]

Im trying to compile using MSYS2 on Windows 11 using this PKGBUILD file.

https://github.com/shoober420/windows-configs/blob/main/C:/msys2/home/shoober420/maelstrom-git/PKGBUILD

Im getting the following error.

I don't have this build environment, so I'm not sure exactly what's happening, but you can just remove snd2wav from the build, it's not actually used by the game.

How should I go about disabling snd2wav? I tried to search for a "--disable-snd2wav" build flag in the Makefiles and configure files and couldnt come across any build flags.

[shoober420]

I went through Makefile, Makefile.am, Makefile.in, configure, and configure.in files in src directory and removed all traces of "maclib". I now get this build error.

compilation terminated. In file included from player.cpp:2: ../Maelstrom_Globals.h:5:10: fatal error: Mac_FontServ.h: No such file or directory 5 | #include "Mac_FontServ.h" | ^~~~

I removed traces of snd2wav from maclib directory Makefile, Makefile.am, and Makefile.in files, and now receive this build error.
