           Summary: Problems with multiple installed Qt libraries (qt and
                    qt-mt)
           Product: kdevelop
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: lang: Python
        AssignedTo: kdevelop-bugs kdevelop org
        ReportedBy: sputnick gmx net


Version:            (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc (GCC) 3.4.2  (Gentoo Linux 3.4.2-r2, ssp-3.4.1-1, pie-8.7.6.5) \
                
OS:                Linux

On my Linux system, there are symbolic links from libqt to libqt-mt, in order to make \
older problems work that don't know about qt-mt. This causes problems when I try to \
build kdebindings:

Making all in python
make[2]: Entering directory `/usr/src/kdecvs/build/kdebindings/python'
cd sip && export QTDIR=/usr/qt/3/ && /usr/bin/python configure.py -b \
                /usr/kde/newcvs/bin -d /usr/lib/python2.3/site-packages
-e `echo -I/usr/include/python2.3 | sed s/-I//` -v /usr/kde/newcvs/share/sip/
Error: These Qt libraries were found: qt qt-mt. Use the -l argument to
explicitly specify which you want to use.
This is SIP 4.0.1 for Python 2.3.4 on linux2.
make[2]: *** [sipdone] Error 1
make[2]: Leaving directory `/usr/src/kdecvs/build/kdebindings/python'

Now I can work around that by changing the kdebindings/python/Makefile to include the \
option -lqt-mt in the following line:

sipdone:
        cd sip && export QTDIR=${qt_dir} && /usr/bin/python configure.py -b \
${exec_prefix}/bin -d ${site_packages} -e ${pytho n_inc_dir} -v ${sip_dir}

But this manual intervention breaks automatic build systems such as Gentoo's portage \
or kdecvs-build.

Would there be a way to automate this, or fix the configuration system such that it \
will recognize libqt and libqt-mt are the same files, or maybe just prefer the \
threaded version anyway if both are found?
