: The problem : 
: When I use a grx fonction(for ex: GrSetMode) in my source and compile it
: I get a message of "undefined reference to 'GrSetMode'" 

: But when I give a "gcc myprog.c .../grx20/lib/libgrx20.a" it's compile fine
: and my .EXE is working.

Well, when it gives you the "undefined reference..." garbage, are you linking 
with the libgrx20.a file?  How I do it is:

gxx myprog.c -lgrx20

(I use gxx and C++)Which tells the linker to link my ".o" with the file 
libgrx20.a in the LIB include path.  I'm pretty sure this is your problem.

ps There are other (better?) ways to get your object code to link with the 
grx20 library, but I try to get by with the minimum of knowledge on 
compilers-too many other things to learn in life :)
