PyQt4-4.8 seems to map the Cursive, Monospace and Fantasy font hints, which AFAICT were only introduced in Qt 4.7.0. Unfortunately qt-gui-4.7.0 is package.masked since September. So, PyQt4-4.8 needs its dependencies towards Qt fixed. It needs Qt 4.7.0. For a quick fix locally, you can either mask PyQt4-4.8 for now, or unmask all of Qt 4.7 (if you feel adventurous -- I'm trying out this option right now).
Created attachment 252145 [details, diff] patch that fixes the problem I had qt-4.7.0_rc1 on my system and it still did not work. needed this patch to qt-gui to get it going. I also have a patch for the ebuild but is trivial.
(In reply to comment #5) > Created an attachment (id=252145) [details] > patch that fixes the problem > > I had qt-4.7.0_rc1 on my system and it still did not work. The _rc1 ebuilds are over at qting-edge overlay. PyQt4-4.8 ebuild is in main tree, so it cannot depend on ebuilds which may not even be available. The PyQt4-4.8 ebuild needs one line changed, QT_VER bumped to 4.7.0. Then it compiled just fine on an otherwise mostly-stable amd64 (given that also Qt 4.7.0 packages available in the main tree are unmasked). Furthermore, PyQt4-4.8 should probably be masked alongside Qt 4.7.0, up until Qt 4.7.0 packages in the main tree are unmasked.
I use Qt 4.6.3 and PyQt4 4.8 has been built for me without any problems.
(In reply to comment #7) > I use Qt 4.6.3 and PyQt4 4.8 has been built for me without any problems. You might be right, and I feel stupid for not realizing it earlier. Now that I look there are Qt_4_7_0 conditionals in PyQt4 sources surrounding the code for the new font hints. Earlier I stupidly relied on compiler error messages and looked directly at Qt sources rather than PyQt4 sources. So, if you have an older version of Qt present then the code for the newer features should probably be filtered away by cmake(?). All systems which felt this bug ... apparently had the unfortunate situation of having at one point installed the Qt 4.7.0_rc1 packages from qting-edge overlay. Those packages did trigger the Qt_4_7_0 conditional, but the Qt rc1 sources didn't yet have the hints in qfont.h -- resulting in the error given in this bug. Only the proper release of Qt 4.7.0 did add the hints. Bummer. Solution is to either downgrade or upgrade Qt away from the overlay-only rc1-version. The main tree ebuilds are just fine, and need no changes. The trouble-causing Qt release candidate ebuilds should probably be nuked from qting-edge. Resolved: invalid?
