As Slávek said this package is still built with the autotools. However when I run the configure script it runs through the script until it stops when it tries to find tde-config. If I change it to kde-config (in the configure script which I know should not be
needed)
it tells me that it cannot find the qt-mt library.
Starting with R14, kde-config is renamed to tde-config. All previous Trinity releases still use kde-config. The trick then is to ensure your build environment is correct. If you are building 3.5.13.x then you use the 3.5.13.x tarballs. If you are building R14, then use the GIT tree as sources rather than tarballs.
R14 is expected to be built against TQt3, which will install a tqt- mt pkgconfig file. If you build with Qt3, as is the case prior to R14, then a qt-mt pkgconfig file is installed.
If you are running 3.5.13.x as your production environment, you can still build R14. Use a second computer, use a virtual machine, use a chroot environment, reboot to a different partition set, etc.
Slavek and Francois build and support both environments. They would be the best people to ask for advice how they manage both environments.
