However,if you know how to manage this, I would really appreciate some example. I'm asking my colleague too if he can
helpme here.
Here's an example from elsewhere in Makefile.shlib:
# If SHLIB_EXPORTS is set, the rules below will build a .def file from that.
# Else we just use --export-all-symbols.
ifeq (,$(SHLIB_EXPORTS))
$(shlib): $(OBJS) | $(SHLIB_PREREQS)
$(CC) $(CFLAGS) -shared -static-libgcc -o $@ $(OBJS) $(LDFLAGS) $(LDFLAGS_SL) $(SHLIB_LINK) $(LIBS)
-Wl,--export-all-symbols-Wl,--out-implib=$(stlib)
else
DLL_DEFFILE = lib$(NAME)dll.def
$(shlib): $(OBJS) $(DLL_DEFFILE) | $(SHLIB_PREREQS)
$(CC) $(CFLAGS) -shared -static-libgcc -o $@ $(OBJS) $(DLL_DEFFILE) $(LDFLAGS) $(LDFLAGS_SL) $(SHLIB_LINK)
$(LIBS)-Wl,--out-implib=$(stlib)
UC_NAME = $(shell echo $(NAME) | tr 'abcdefghijklmnopqrstuvwxyz' 'ABCDEFGHIJKLMNOPQRSTUVWXYZ')
$(DLL_DEFFILE): $(SHLIB_EXPORTS)
echo 'LIBRARY LIB$(UC_NAME).dll' >$@
echo 'EXPORTS' >>$@
sed -e '/^#/d' -e 's/^\(.*[ ]\)\([0-9][0-9]*\)/ \1@ \2/' $< >>$@
