Build Problem Qt5.4.1 on Fedora 17

[Bruce Taber <b.taber@…>]

Having troubles linking binaries when building master/0.28 using Qt5.4.1. Qt5 gets installed into /opt by using the supplied qt-opensource-linux-x64-5.4.1_2015-02-20_12-26-10-119.run file.

The specific error is:

I have this vague recollection that there were various libicu linking issues with Qt5 even as far back as the original beta. I thought that they had (mostly) been resolved, but then again, F17 is so old and unsupported that there may very well be bugs with Qt 5.4.1 on F17 (and I know the Fedora community would not care (F17 is EoL), and I doubt the Qt community will care (F17 is EoL)).

Off hand, it sort of looks like the link path is not complete (should be /opt/Qt5.4.1/5.4/gcc_64/lib ?) You might try an explicit CXXFLAGS to configure to see if you can work around it (or figure out where the path is passed along wrong)
