Isn't TQT3 supposed to be installed in /usr ? So that libraries are under /usr/lib64 directly ... that's what I do and it works very well ... If TQT3 is in non-standard prefix (ex: /opt/trinity), you can modify the "configure" script a bit more than I did. Look at the line "for p in /usr/lib64/tqt /usr/lib/tqt ..." . These are all the path where we look for TQT3 libraries. Just add the path you want, like ${PREFIX}/lib64 and ${PREFIX}/lib at the beginning the path list, and it should do the trick. If you have too much trouble with this "configure" script, you can stop using it and build tqca directly with only 3 commands ! (just check that the "qmake" command is in your PATH ...) export QTDIR=/opt/trinity qmake qca.pro make Francois
