Osx weak link framework/dylib

[mirswith]

Is it possible to weak link an osx framework as well as a dylib using QtCreator and if so, how?

Thanks!

That has nothing to do with Qt Creator, it just calls regular make + makefiles. Just add the weak linked libraries to the LIBS variable:

@
LIBS += -weak_framework <framework_name>
@

PS: for weak linking of a library use

@
LIBS += -weak_library <library name>
@

See "Apple's documentation":http://developer.apple.com/library/mac/#documentation/MacOSX/Conceptual/BPFrameworks/Concepts/WeakLinking.html for details.

Thanks. I was just about to post my findings and found your answer. :)

After diving into this I would have asked a different question of how to lazy load a shared library. I want strict linking on the symbols but to load the library only when needed. Also I apologize for not looking at the ld man page before asking this question (didn't occur to me); maybe it will save someone down the road some time. :)

With that said, for those interested this is how to lazy load a shared library on osx:

@-L../mylib/dir/ -lazy-lmylib@

Thanks again!
