There is not really, but if you want to download the versions on the CVS and tell me what does prevent them to work on Linux I'll try to fix it...
I have downloaded glest_map_editor sources from CVS, and tried to compile them. There is some problem with the strict type checking of the most recent C++ compilers. For example, the call of pow with two ints is ambiguous to g++ 4.0.1, but this is easily solved by casting of the first argument to double, i.e.
pow( static_cast<double>(i+1), i-j ) // if I remember well.
There is however a major issue in ubuntu because the libwxgtk 2.6.1 is compiled with unicode. So I had to modify unicode=no to unicode=yes in configure.ac to successfully configure the package, but after this there are a lot of problems in converting string to/from wxString.
I'm trying to solve these problems, but I have never used wxgtk. However it is possible to use the glest_map_editor executable for windows with wine.
