Hello everyone,
I have been trying to build eDuke32[1] (a Free source port of Duke Nukem 3D)
with Guix following their instructions[2], but it looks like I am unable to
set up the environment properly. I first created the following Guile script
(omitting some version, source, description and synopsis for brevity):
(define-public eduke32
(package
(name "eduke32")
(build-system gnu-build-system)
(arguments `())
(native-inputs
`(("pkg-config" ,pkg-config)))
(inputs
`(("sdl-union" ,(sdl-union (list sdl2 sdl2-mixer)))
("glu" ,glu)
("libvorbis" ,libvorbis)
("libvpx" ,libvpx)
("flac" ,flac)
("gtk+" ,gtk+-2)))))
Then I typed `guix environment --load=eduke32.scm` in my shell to set up the
build environment, and executed `make`. This works at first, it builds the
following files:
https://pastebin.com/FyJKK6BD
Then it fails at this step:
In file included from source/build/include/mutex.h:10:0,
from source/build/include/osd.h:12,
from source/build/include/baselayer.h:11,
from source/duke3d/src/duke3d.h:28,
from source/duke3d/src/sdlmusic.cpp:35:
source/build/include/sdl_inc.h:63:25: fatal error: SDL_mixer.h: No such
file or directory
compilation terminated.
Failed building obj/duke3d/sdlmusic.o from source/duke3d/src/sdlmusic.cpp!
make: *** [GNUmakefile:982: obj/duke3d/sdlmusic.o] Error 1
Looking into the offending file shows the following code:
#if defined NEED_SDL_MIXER
# if defined SDL_USEFOLDER
# if SDL_TARGET == 2
# include <SDL2/SDL_mixer.h>
# else
# include <SDL/SDL_mixer.h>
# endif
# else
# include "SDL_mixer.h"
# endif
The second-to-last line is line 63; the compiler looks for the header file in
the same directory as the source file, which is obviously wrong. So it seems
like my environment specification did not set up SDL properly. Can someone who
has experience with SDL please help me out to understand what is going wrong
here?
