You should BR qt4-devel rather than qt-devel, since qt-devel is (used to be) provided by qt3-devel as well, and yum now prefers that because it has fewer dependencies. We're dropping the Provides: qt-devel from qt3-devel at least from F14 on, as per bug 623106. But still, you should always have used qt4-devel, it was just luck that you haven't hit this yet. (And, on the other hand, qt4 is just a virtual Provides of the qt package, so filing bugs against qt4 is wrong. Yes, it's complicated. ;-) ) *** This bug has been marked as a duplicate of bug 623106 *** I've just looked in: http://download.fedora.redhat.com/pub/fedora/linux/updates/testing/14/x86_64/ and http://download.fedora.redhat.com/pub/fedora/linux/updates/13/x86_64/ Both packagages are qt-devel not qt4-devel hint, $ rpm -q --whatprovides qt4-devel qt-devel-4.6.3-8.fc13.x86_64 :) And rpm -q --whatprovides qt-devel returns: qt3-devel-3.3.8b-29.fc13.i686 qt-devel-4.6.3-8.fc13.i686 So. If BuildRequires: qt-devel >= 4.0 is in the spec file, why do I get CMake Error at /usr/share/cmake/Modules/FindQt4.cmake:1151 (MESSAGE): Qt qmake not found! When it is provided by qt-devel >= 4.0? Partly because qt has an epoch, this works too, BuildRequires: qt-devel >= 1:4.0 Because qt3-devel-3.3.8b Provides: qt-devel = 1:3.3.8b qt-devel-4.6.3 Provides by identity qt-devel = 1:4.6.3 1:3.3.8b > 4.0 (because 4.0 = 0:4.0) 1:4.6.3 > 4.0 so both match and yum picks qt3-devel due to it having fewer dependencies (the latest behavior change in yum; before, it would pick qt-devel due to the shorter name). You should use: BuildRequires: qt4-devel which is provided only by qt-devel, not qt3-devel, and which is provided without Epoch, so e.g.: BuildRequires: qt4-devel > 4.6 actually does what you expect it to do. With qt-devel, you'd have to write: BuildRequires: qt-devel > 1:4.6 to require at least 4.6, just qt-devel > 4.6 would always match. And in addition, qt4-devel will continue working when we will have Qt 5. Oh, and actually, you probably want >= 4.0 rather than > 4.0, too (likewise for the >= 4.6 in my examples). That's what's in the spec file BuildRequires: qt-devel >= 4.0 Sorry guys... This is beginning to sound to much like Fisbin (Its a Star Trek reference). This is starting to get to complicated for the likes of me. Probably at the beginning of the week I will be orphaning stuff. I will post an alert on mailing list. Hopefully others will pick up the packages. Keep up the good work. > That's what's in the spec file > > BuildRequires: qt-devel >= 4.0 And that's wrong. It should be: BuildRequires: qt4-devel On reflection... I managed to fix the issue that I had with the package that I'm maintaining with a reletively simple fix. Be that as it may. It would be helpful if the package name and version reflected the information required in the buildrequires line of any given spec file. It would avoid dumb questions / bug reports like this one |
