In the mean time I did an upgrade to Qt 5.4 on RHEL, using the installer from the Qt website, which proved to be much easier than I had anticipated, and move on from 4.6.2.

Marking as confirmed, but lowering the priority as most distributions will have Qt 4.8 or better. It would be relatively simple to add a configuration test in m4/acinclude.m4 and then use #if defined in file-editor-tab.cc to choose between two different code options. As an example of how to code such a test, see

I don't have time to work on this myself.

I think we might want to continue to support Qt 4.8 if it's not too much trouble, since that is the last release of Qt 4 and still widely available. But yes, dropping Qt 4 completely is an option.

Most of the Qt feature tests are commented with the corresponding minimum Qt version.

The only mainstream distros that have Qt 4.6 and not Qt 4.8 are Red Hat Enterprise and CentOS (both 6 and 7).

Maybe we should just drop al Qt4 support at the next release (4.6.0).

compilation fails with this error:

QDateTime::currentDateTimeUtc() was introduced in Qt 4.7 according to http://doc.qt.io/archives/qt-4.8/qdatetime.html#currentDateTimeUtc
