Statically Link the SDL library

SDL Development
1

I’m have an object file that I’m creating which is going to be used as a
plugin for another application. The object file that I’m creating uses some
SDL functions and I would like to link it statically. Before I was linking
dynamically by the use of dlopen() and dlsym(). I have added the following
to lines to my homegrown makefile

SDL_CFLAGS := $(shell sdl-config --cflags)
SDL_LDFLAGS := $(shell sdl-config --libs)

here is the output of those two commands:

sdl-config --cflags : -I/usr/include/SDL -D_REENTRANT
sdl-config --libs : -L/usr/lib -Wl,-rpath,/usr/lib -lSDL -lpthread

I’m running RH, kernel 2.4.7-10. I installed SDL from the .rpm.

It seems that my library file is not much bigger after I added these two
lines. I thought it would be significantly bigger since I’m now including
the SDL functions in my library. Is there something that I’m missing?

Regrads,
Tim

sdl-config --cflags : -I/usr/include/SDL -D_REENTRANT
sdl-config --libs : -L/usr/lib -Wl,-rpath,/usr/lib -lSDL -lpthread

You’re linking against the shared library…effectively, you’ve got the
same thing as before, except it’s doing the dlopen() and dlsym() work
for you.

Make sure you aren’t violating the LGPL license, then link against
/usr/lib/libSDL.a.

I’ll check the license, and how do I link against /usr/lib/libSDL.a ???_______________________________________________

Use:

sdl-config --cflags (same)
sdl-config --static-libs (instead of --libs)
