You need to call dlsym(). A later dlopen() cannot fix a missing weak symbol. A weak symbol reference only gets one chance to resolve. If the symbol is not present at load time, then the reference is set to NULL and won't change after that. -- Greg Parker [email protected] Runtime Wrangler _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
