Hello,
I'm building a framework which includes a couple open source sub-frameworks. Specifically, I'm making a framework, SimpleGameFramework ( SGF.framework ) which is laid out as such:
SGF.framework
Versions
A
Headers
-my headers
Resources
-various bits and pieces
Frameworks
- SlotSig.framework
- GLEW.framework
My intent for SGF.framework is that it be completely self contained -- that I should be able to embed it in the Contents/Frameworks subfolder of the app I'm building and that app would be ready-to-go, which is to say, no external dependencies. I know about setting @executable_path/../Frameworks and have used that before for single frameworks, but not for frameworks which include other frameworks.
My issue is linking to the sub frameworks. Since they get copied into SGF.framework/Version/A/Frameworks I set their Install Dir to @executable_path/../Frameworks/SGF.framework/Versions/A/Frameworks -- I also tried the vanilla @executable_path/../Frameworks. Neither works -- I get the following linker error:
/usr/bin/ld: warning can't open dynamic library: @executable_path/../Frameworks/SGF.framework/Versions/A/Frameworks/SlotSig.framework/Versions/A/SlotSig referenced from: ../../sgf/build/Debug/SGF.framework/SGF (checking for undefined symbols may be affected) (No such file or directory, errno = 2)
/usr/bin/ld: warning can't open dynamic library: @executable_path/../Frameworks/SGF.framework/Versions/A/Frameworks/GLEW.framework/Versions/A/GLEW referenced from: ../../sgf/build/Debug/SGF.framework/SGF (checking for undefined symbols may be affected) (No such file or directory, errno = 2)
/usr/bin/ld: Undefined symbols:
SlotSig::SignalBase::~SignalBase()
SlotSig::SlotsSetBase::connect_from(SlotSig::SignalBase*)
... and so on.
What's very interesting is that if I use ZeroLink, I get a warning -- but the app runs -- meaning the linker *is* finding the nested frameworks. But without zero link I get the above.
Does anybody have any suggestions? I mean, other than simply giving up and rolling GLEW and SlotSig into SGF -- I'd prefer to avoid that since both projects are updated periodically and I'd like to keep their builds separate.
