Are you skipping the auto configure step? You shouldn't.
http://home.tele2.fr...t/changelog.txtthere you will find a few tutorials link (at bottom) and a link to a precompiled Mai 2007 version
However, the result of compilation is a .xbe that needs the original xbox operating system to run.
So you will have to switch from linux to a dashboard in order to run .xbe (I think).
(Usually Linux removes all traces of previous operating system from memory, I think)
I'm only using cygwin under Windows, so I can't really help other platforms toolchains.
(frankly it's easier to compile on PC and have the makefile automatically send .xbe through ftp)
