[Qgis-developer] Building QGIS in Mac OS X (Mountain Lion i.e. 10.8) with QtSQL support

[William Kyngesburye]

It might be a while before I get to Mountain Lion, for various reasons.

For running existing software on Mtn, I expect few problems.  Apple usually does a good job of forward compatibility if the software was built for the previous version or 2.  Also, this time there shouldn't be a Python change - there is no Python 2.8, and 3.x is a big jump (not just for Apple).  Can you verify the default Python version is still 2.7? (it will still be there anyways)  In any case my Python installers should be able to reinstall Python modules removed by the upgrade.

Qt software should run, but there may be small glitches.

Compiling on Mtn for Qt may have problems.  The fix in that link may not be absolutely necessary.  As I remember, Qt just spews out warnings on new OSX versions, the fix just removes those.  Also, you can use an SDK to compile for Lion and you shouldn't get those warnings.

All generalizations are dangerous, even this one.
