Problem while linking SDL_mixer-1.2.0 statically

Paresh · February 21, 2002, 8:05am

Hi,
I am using SDL-1.2.2, SDL_mixer-1.2.0 on RH6.2 platform. In my game I
want to link SDL as well as SDL_mixer statically but mixer gives me
’Undefined reference to …" error. Following is the part of my Makefile:

LIBST= -L/usr/local/lib -L/usr/local/lib -Wl,-rpath,/usr/local/lib -lSDL -lp
thread -lm -L/usr/X11R6/lib -lX11 -lXext -lXxf86vm -lXxf86dga
/usr/local/lib/libSDL_ttf.a
usr/local/lib/libfreetype.a -L/usr/local/SDL-1.2.2/test/SDL_mixer-1.2.0/.li
bs -L/usr/local/SDL-1.2.2/test/SDL_mixer-1.2.0/mikmod/.libs -L/usr/loacl/SDL
-1.2.2/test/SDL_mixer-1.2.0/timidity/.libs -L/usr/local/SDL-1.2.2/test/SDL_m
ixer-1.2.0 /usr/local/SDL-1.2.2/test/SDL_mixer-1.2.0/.libs/libSDL_mixer.a

I tried many ways of linking the mixer statically ie remove all '.so'

files from /usr/local/lib folder. In this Makefile I am explicitly trying to
link ‘.a’ file of SDL_mixer. I even tried SDL_mixer-1.2.1. I get following
error:

/usr/local/SDL-1.2.2/test/SDL_mixer-1.2.0/.libs/libSDL_mixer.a(mixer.o): In
function mix_channels': /usr/local/SDL-1.2.2/test/SDL_mixer-1.2.0/mixer.c:119: undefined reference toSDL_MixAudio’

to SDL_FreeWAV' /usr/local/SDL-1.2.2/test/SDL_mixer-1.2.0/mixer.c:329: undefined reference toSDL_FreeWAV’

If I use the '.so' file (ie link SDL_mixer dynamically) I do not get any

errors. I also noticed one thing that one cannot compile SDL_mixer only
statically (ie generate only SDL_mixer.a file) if there is no ‘.so’ file of
SDL (ie libSDL.so…) file in the /usr/local/lib directory.
Am I doing anything wrong? I want to link all the SDL libraries statically.

regards,
Paresh.

You might want to link statically via the gcc command line option
"-static"

Because SDL_mixer depends upon SDL, -lSDL should appears
after -lSDL_mixer in your link arguments (just think that you
use a library to supply symbols required by previous objects).

I do this everytime I cross-compile SDL for MinGW: just
configure both libraries with --disable-shared --enable-static.–

It worked after adding -lSDL. Thanks a lot.
