The thread is really old. The patches aren't valid anymore.
As I said, only the map editor is available for linux and it builds with the rest of glest.
Where did you get the glest game from? Some distributions patch the map editor out (don't know why), but maybe you have luck and it is included in the glest package. Just have a look before you go on. It's called glest_editor.
To compile glest and the map editor you have to download the source package of glest.
official:
http://sourceforge.net/project/showfiles.php?group_id=127297&package_id=141386titi's:
http://www.titusgames.de/glest-source-3.2.1.tar.bz2The only difference is that titi included some files generated with autotools (autogen.sh). So just for simplicity take the latter.
After unpacking take a look in README.linux. This should explain most things.
The list of dependencies is incomplete. You also need lua 5.1 and wxWidget 2.8. Just pull it all down through your package manager and make sure you also get the -dev or -devel versions of the libraries, e.g. liblua5.1-0-dev, libogg-dev.
Then just run:
./configure
jam
as stated in the readme. The map editor is called glest_editor.
