Hi,

It has been some time I haven't build it.
There is something weird with the endianness here. The MIPS build should use
the -EL option to build for little endian.

Did you follow the instructions
here<http://wiki.github.com/paul99/v8mips/building-v8mips>
?
Also you should try to build the "integration" branch. This branch should
always compile and work (kind of dev branch).

Alexandre
