Hi, I get this error during the compilation:

Seems like my build fails with the same error (both cvs and the release):

Sorry, just re-read the build instructions, especially the "if the build fails on the GuiScript object"-part, and guess configure looks up the wrong python version. There are 2 different installations on my system, one of python 2.4 that came with the distro and another one of v. 2.5 that I installed this day with the "--enable-shared" on. The point seems to be: How to tell configure that it should use the latter?

Easiest way would be to modify the detection script manually (on your system) to look for 2.5 only.

It's strange, becouse I use Ubuntu, and its packages are built with --enable-shared. I'm quite sure of this also because I didn't encounter this problem before, and I've not updated the python package in a while.

The reason here is that gcc 4.1 is more strict with aliasing than previous versions, and python is a bit sloppy with aliasing rules. Add a -fno-strict-aliasing option to the cflags in configure.in and re-run autogen.sh. I don't have the gemrb sources around here, so I can't tell you the exact lines to edit unfortunately.

Thanx, that solved the problem.
