I downloaded the source tarball for qt-4.2.2, configured it with --prefix=/usr/local --no-stl (because Slackware does not support STL; at least, it didn't), ran make, and 53 minutes later ran 'make install.'
In /usr/local/lib/ there are libQt*.so.4.2.2. When I configure lyx-1.5, I specify --with-frontend=qt4, but it fails: Qt 4 Frontend: Qt 4 version: Packaging: posix LyX binary dir: /usr/local/bin LyX files dir: /usr/local/share/lyx **** The following problems have been detected by configure. **** Please check the messages below before running 'make'. **** (see the section 'Problems' in the INSTALL file) ** qt 4 library not found ! What have I done wrong? I've not compiled Qt in years. Thanks, Rich -- Richard B.
