Update of bug #37101 (project octave):
Summary: GUI build fails on FC 17 x86_64 => GUI build fails
on Fedora or RHEL with qt3-devel installed
Follow-up Comment #2:
The problem was the presence of qmake from Qt version 3 in the PATH, which
configure found and used before qmake-qt4.
Fedora and RHEL systems install Qt4 qmake as /usr/bin/qmake-qt4. Qt3 can be
co-installed, and its qmake executable is just qmake.
yum erase qt3-devel
is a workaround for this problem.
Validating the output of qmake should be enough to tell it's a version we can
work with, here are some examples on a Fedora 17 64-bit:
address@hidden ~]$ qmake-qt4 -query QT_INSTALL_HEADERS
address@hidden ~]$ qmake -query QT_INSTALL_HEADERS
address@hidden ~]$ qmake-qt4 -query QT_INSTALL_LIBS
address@hidden ~]$ qmake -query QT_INSTALL_LIBS
If no valid paths are found from qmake, configure should keep searching for
qmake candidates in PATH.
