I tried this command below:

/usr/bin/gcc  -melf_i386  -shared -Wl,-soname,libMySdk.so.1 -o libMySdk.so
$(OBJS) -Wl,--exclude-libs,ALL $(LIBS) $(SUBLIBS)

where:
    - $(OBJS) contains my SDK's objects files (*.o)
    - $(LIBS) contains -L and -l statements
    - $(SUBLIBS) contains the path to the home-made sub-libraries .a files

But this did not do the trick, and the symbols from $(LIBS) still get
exported in the .so shared object.

What am I missing ?

Thanks,
Florent.
