Part of the distro on Ubuntu
Had to build it on SuSE. Required Qt version 4.2 or better. This comes with SuSE 11.1
wget http://www.xm1math.net/texmaker/texmaker-1.6.tar.bz2 tar xjf texmaker-1.8.tar.bz2 cd texmaker-1.8 ./BUILD.sh
Feed it the appropriate prefix (in our case /usr/local/shared/suse-11.1/texmaker/1.8). You don't need to be root for most of it despite what the instructions say; you just need to do the last 'make install' stage as root.
I had to edit texmaker.cpp in the source directory to set the 'Tools/Dvi' viewer to be xdvi rather than evince; the evince the SuSE 11.1 image doesn't have dvi support.
Built this as a 32-bit app. Requires libqt4-x11-32bit installing on the 64-bit machines.
