Hello, I am trying to build Haiku from its sources on Linux. After checking out trunk/ and buildtools/ I just built and installed jam successfully. Unfortunately when I build following the cross compile howto it says (building the cross compiler) that x86_64-unknown-linux is not a valid system. I'm using Kubuntu Feisty on a AMD 64 X2 (x86-64). Anyone has got the same problem? PS: Now I am trying to build with GCC4 although the read me says that it's better to build with 2.95.
