mythtv apparently does not compile using qt4, and is not to be ported to use qt4 in the short term. I have both qt-3.3.4-r8 and qt-4.0.1 emerged on my system. When I try to re-emerge mythtv, it incorrectly chooses qt4 to compile/link with. The reason I'm trying to re-emerge mythtv is that I upgraded to mysql 5.0. I whacked all the mysql databases on my system and am rebuilding them. Mythtv is the last one. Reproducible: Always Steps to Reproduce: 1. Have qt4 emerged on your system. 2. Try to re-emerge mythtv 3.

Ok, I don't think I can actually blame this on the ebuild. It looks to be more like problems with mythtv and the way that it calls qmake. I'm thinking that if I linked /usr/bin/qmake to /usr/qt/3/bin/qmake, that it'd probably emerge ok. Then revert /usr/bin/qmake back to normal again. If anyone tries this, please drop a comment here.
I gave this a try last night and it worked. I symlinked /usr/bin/qmake to /usr/qt/3/bin/qmake and then did the re-emerge of mythtv and it succeeded. I them moved my saved copy of the real /usr/bin/qmake back and things are more or less back to normal. Not normal because mythbackend still can't connect to the database due to: # mythbackend QSqlDatabase: QMYSQL3 driver not loaded QSqlDatabase: available drivers: 2005-12-01 07:21:41.817 New DB connection, total: 1 2005-12-01 07:21:41.818 Unable to connect to database! 2005-12-01 07:21:41.818 No error type from QSqlError? Strange... 2005-12-01 07:21:41.819 Failed to init MythContext, exiting.
Ok, I believe I have my qt/mysql problem figured out now. I upgraded to mysql 5, and rebuilt qt, ran revdep-rebuild, etc etc... However, mythtv was still using qt-3.3.4-r8 (as it should have been doing) - however, the sqlplugin for this version of qt was still referencing the *old* libmysqlclient.so... which no longer existed. Finally it dawned on me that revdep-rebuild wasn't catching the dependency and hadn't rebuilt qt-3.3.4-r8. I did this manually, and now mythbackend can at least connect to the mysql database again. Problem solved. Though - this problem with revdep-rebuild not catching the issue should probably be a separate bug. This bug I'll leave open as I think that the mythtv should either: 1. upstream mythtv should be fixed to properly call qmake 2. the ebuild should patch the mythtv source to properly call qmake It does it wrong on systems that have both qt-3 and qt-4 installed. And of course, mythtv won't compile against qt-4.
