And looks like it depends on the stuff in ./mkspecs/linux-g++-64 specifically the qmake.conf file I remember having to tweak something (been a while since I changed versions of qt, have re-compiled it for 9.3 though).

Hello,

I tried to compile some Qt applications on a new installed Suse 9.3 on a AMD 64 bit processor. After ./configure --prefix=.....

I get the error .... checking for libjpeg6b... no checking for libjpeg... no configure: WARNING: libjpeg not found. disable JPEG support. checking for perl... /usr/bin/perl checking for Qt... configure: error: Qt (>= Qt 3.2) (library qt-mt) not found. Please check your installation! For more details about this problem, look at the end of config.log. Make sure that you have compiled Qt with thread support! ....

config.log shows

libqt-mt is present in a 32 and a 64 bit version:

Any ideas?
