Note that you do "make install" on Qt-4, you do not install it in place so the source code should be unpacked in: /usr/src/ with our other sources. Therefore, you shouldn't have any problem. The only issue is that you need to see that the configure scripts find the correct one when compiling and set your path to find the correct "moc", etc.. Normally stuff that uses Qt-3 will use the environment variable QTDIR to indicate where to look for Qt and this doesn't seem to be the case for Qt-4. You will probably have to tell it where to find it. -- JRT ___________________________________________________ . Account management: https://mail.kde.org/mailman/listinfo/kde.
