Congrats!  It looks like there's something wonky about glibc that causes segfaults -- I see that they're using uClibc.  I had good luck with diet libc.

Actually, there are 2 buildroots there... uclibc and glibc, both work fine... but the glibc version generates larger files so I compiled busybox as uclibc...  I tried both tho

Yes, I can confirm that the diet libc and crosstool combo detailed on the wiki page works well. :-)

it works for some things, but it won't compile any larger programs such as busybox

busybox compile blows up with diet, some functions not allowed or something... and if you compile w/o diet it segfaults...

with the ones I listed, it works fine as glibc or uclibc... and I've got a recompile of the crosstool for different settings running, hopefully that will give me a working cross-compile environment also

Can you update the wiki page with your findings? I'd be interested to see a bit more detail on this and it would probably be useful for others too.
Thanks

I plan on it, soon as I'm done testing crosstool with a few different opts

Wiki updated with how to build a crosstool that doesn't segfault... I don't want to link to the precompiled one because I don't really know how they compiled it etc.

Anybody who knows how to build uclibc for it, please update the wiki ;)
