Compilation error on Linux

[Emeraude]

I'm trying to build the game using the following commands :

swfmake -f loader.xml
swfmake -f swfmake.xml 

Both those commands fail, with errors related to the zlib compression.
Here are more detailed information I got while using the verbose option of the compiler:

> swfmake -v -f swfmake.xml 2>&1 | tail

Error : zlib_deflate_end

In both those examples the zlib functions are returning -1 but there ain't an error message to explain what's going on.

A workaround I found is to completely disable compression (by editing the makefiles and the swf files included in swfmake.xml) but I don't think it's a solution we should rely on.
