Re: [vox-tech] Qt/C++ libraries question



In case anybody cares, the answer to my question is this:

1. rebuild qt itself to support the static library (./configure -static;
make).  this adds a libqt.a where you have the various
libqt.so files.

2. once you have this in place you can just throw -static onto your g++
command line or into your makefile

3. since qt/mac is not the same as qt/x11 (qt/mac speaks directly to aqua)
you have to do the above steps on a mac.  for any other unix a
cross-compile would work.

4. now give your (obviously more bloated because of the static build)
application to your mac buddy.

5. if time/cleverness permits, bundle everything in the correct place
within a directory with a .app extension to bring
the double-clickable mac experience to your application (note: i haven't
figured this one out quite yet, but i'm doing some reading right now).

Thanks to everyone who replied!
