When I try to configure ROOT with --with-qt-incdir=/A/Path/include, the config finds Qt/qglobal.h. It then searches for a QT version, and returns
As far as I can tell, the problem comes when the configure searches /A/Path/include/Qt/qglobal.h for the string
"#define QT_VERSION_STR". But Qt/qglobal.h contains only a macro warning that this file (and all files in Qt/) are now obsolete, and
The file QtCore/qglobal.h does contain the string “#define QT_VERSION_STR”, but since this file is not searched by the configure script, ROOT is not compiled with qt support.
I dont know what version of qt4-mac the ‘Qt/’ directory became obsolete in.
I have a workaround for this:
I have inserted the following lines at line 3222 of the configure file.
qtverneed="4.3.0" qttoonew="5.0.0" qttestdir=$qtmainincdir/../src/corelib/global if test ! -d $qttestdir ; then #NEW qttestdir=$qtmainincdir/QtCore #NEW fi #NEW if test ! -d $qttestdir ; then qttestdir=$qtmainincdir/Qt fi
This worked for me, since it gives preference to the QtCore dir. The compile succeeds, but drops the warnings
/A/path/include//Qt/qlineedit.h:3:10: warning: "Inclusion of header files from include/Qt is deprecated." [-W#warnings] #warning "Inclusion of header files from include/Qt is deprecated."
I can not test the configure file for other versions of qt. Anyway, this fix will only work so long as qt4-mac keeps the (now obsolete) ‘Qt/’ directory. If they decide to delete it, the configure will succeed, but the compile will fail.
OS: OSX 10.8.4
ROOT version: 5.34/02
Qt Version: 4.8.4 (Installed via macports firstname.lastname@example.org_6).
