There is a linux crosscompiler on the www.playstation2-linux.com site
http://playstation2-linux.com/projects/ps2stuff
Hope this helps
I'm trying to figure this one out myself as well since config.guess
comes up with mipsel-pc-linux-gnu, BUT it does not conform to the
standard O32 ABI. the PS2 passes doubles in 2 general purpose registers.
It might be possible to check for PS2 specific header files though. I'd
much prefer it would work without a switch as well. And if you want me
to try something on my machine, let me know.
Greetings,
Dylan Schell
