There are three installers provided. Normally you would get medit-x.x.x.exe which
includes GTK libraries. There are also
medit-no-gtk-x.x.x.exe which doesn't include GTK, and
medit-python-x.x.x.exe which includes GTK and
Python. Use these if you have special needs.
If you are on unix, get source tarball medit-x.x.x.tar.bz2. For
detailed installation instructions and configure options refer to INSTALL
file in the source tarball, but usual ./configure && make && make install
should suffice.
After you built medit, you can run it without installing, but it won't find
syntax highlighting files, tools config files, and whatever else it likes to
have. Therefore, make install is required.
In case of problems please contact me.
