gcc -static on Solaris

[Marc <marc upr41 univ-rennes1 fr>]

Thanks to those who provided me help on my last question (about gcc
warning...).

I have another problem with gcc under Solaris.

Here is the linking part of my Makefile:

gcc -static my_object_files.o \
/usr/local/lib/libgtk.a /usr/local/lib/libgdk.a /usr/local/lib/libglib.a
\
-L/usr/openwin/lib -lX11 -lXext -lm -lsocket -lnsl -o my_prog_static

I have no problem with this when compiling under Linux (libc5).
But here are the error messages I have when compiling under Solaris.

Undefined                       first referenced

my_prog_static

Any hints ?
