I'm wondering if it wouldn't be better to set the value of stlib for
windows, instead of changes like this:
- $(CC) $(CFLAGS) -shared -static-libgcc -o $@ $(OBJS) $(LDFLAGS)
$(LDFLAGS_SL) $(SHLIB_LINK) $(LIBS) -Wl,--export-all-symbols
-Wl,--out-implib=$(stlib)
+ $(CC) $(CFLAGS) -shared -static-libgcc -o $@ $(OBJS) $(LDFLAGS)
$(LDFLAGS_SL) $(SHLIB_LINK) $(LIBS) -Wl,--export-all-symbols
-Wl,--out-implib=lib$(NAME).dll.a
I'm also wondering if changing this will upset third party authors.
Thoughts?
cheers
