[Octave-bug-tracker] [bug #55735] QGLWidget not detected, so Qt graphics toolkit is not compiled

[Mike Miller]

Follow-up Comment #3, bug #55735 (project octave):

Have you been able to verify that you can build if CPPFLAGS is set correctly?
For example


../configure ... CPPFLAGS="-I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui
-I/usr/include/qt4/QtHelp -I/usr/include/qt4/QtNetwork
-I/usr/include/qt4/QtOpenGL -I/usr/include/qt4/QtSql
-I/usr/include/qt4/QtXml"


adjusting directories as necessary for your system. There's no need to hack or
patch configure just to pass some extra -I options. If that works, then I
think that is a reasonable workaround for users needing to build Octave 5 with
Qt 4.

Your attachments probably aren't going through because they are too large,
Savannah only accepts attachments under about 2 MB despite what the note on
the page says. I'm not sure that attaching the configure script will provide
us with any more information.
