[vtkusers] VTK deployment with static libraries on Mac (and in Qt Creator)

[Richard Brown]

Hi David, Elvis,

I’ll stick to dynamic libraries in that case.

After a bit of reading I think I need to copy the dynamic libraries into the app bundle then use install_name_tool to sort out all the paths.

Thanks for the help,
Richard

Hi Richard,

It is possible to build dynamically-linked applications with Qt and VTK, and to share such applications.  On the Mac, the Qt libraries become part of the app bundle.  I do not know how to do this with Qt Creator, but there should definitely be Qt experts around who know how to do it.  Maybe not on the VTK list, however, since I don't think that many of us here use Qt Creator.

There are two strong reasons for using dynamic linking with Qt:
1) it allows you to use the Qt binaries from the Qt download site.
2) it allows you to use the Qt LGPL license without releasing your code

Reason (2) is important.  If you use static Qt libraries, then you must either pay for a Qt license or else release your own code as LGPL or a compatible open-source license.

So sounds more like a Qt problem problem, to be asked on a Qt list...

(I've never used Qt, so alas have no further suggestions.)
