Hi Steve,

I also want to build a root file system for the target.
I tried to build the tool chain you described above.
I used crossdev on gentoo: "crossdev --arch=mips --vbinutils=2.15.91.0.2 
--vheaders=2.4.25 --vgcc=3.4.3 --vglibc=2.3.4.20041102"
But it fails.

How did you build the tool chain?
What kernel headers did you use?
If I use kernel headers 2.6.8.1 (I realy need 2.6 heraders!)  the 
installation of the headers fails!

It would be great If you can tell me which paramerter I have to use with 
crossdev to get a working tool chain.
