No link errors that I can see (with ZL on or off). With ZL on I see
this in the build log.
Bundlizing
/Users/simeon/Documents/Source/ImageShare/build/ImageShare.build/
ImageShare.build/Objects-normal/ppc/libValidate.ab libValidate.a
With ZL off, I see an Ld command that includes -lValidate.
In response to Timothy J. Wood <email@hidden>,
I have no access to the source for the library it will have to just
stay a .a.
I haven't used -all_load before, but i just tried setting the
development build to Zero-Link on and adding -all_load to the other
linker flags settings. This did not fix the issue. Did I do what you
had in mind? Does a linker of and kind get called when zero-link is on?
