hi,

I suspect I may have found a bug in libtool on Darwin/OSX, although it's possible that I am not using automake, etc correctly.

Basically I'm trying to compile my qt module for qore (https://trac.macports.org/browser/trunk/dports/lang/qore/Portfile ) against the qt4-mac port.

I have modified my configure.ac script to do more generic framework detection, and set up the CPP_FLAGS and LD_FLAGS properly for frameworks in non-standard directories (such as /opt/local/Library/ Framework, where the QT libraries are placed by default from macports).

While building the qt-core module, I build a shared library and link it to the QtCore framework. Then I build a module that links to the shared library (the reason I do this is that I have other modules that depend on the first module, and in order to share code and symbols easier, I put all the shared code in the shared library).

However, libtool is creating the .la file for the shared library without the -F<framework-dir> option in the inherited_linker_flags line, although the "-framework QtCore" is there.

So when the module is created, it fails in the link step because the QtCore framework cannot be found, because the -F<framework-dir> option is not present in the inherited_linker_flags line in the la file.

I have tested building the project by manually editing the inherited_linker_flags line for the shared library, by both adding the missing -F<framework-dir> option and by removing the -framework QtCore line, and it works both ways. So I guess either the -framework option should not be inherited or the -F option should be inherited, but not one without the other.

I am not able to fix this bug myself, I don't understand entirely how libtool works, and I'm afraid I'm not even an expert user of it.

Anyway, I hope someone can help me with this.

I'd like to be able to release a port for my qt module for qore, but I have to make sure that macports users can build it automatically first.

thanks again
David
