Hello,
I try to get a cross compiler based on gcc-3.4.2 glibc-2.3.2 binutils-2.15 working; without success.
Is anyone using a cross compiler base on gcc-3.4.x for a mips big endian target?

I've got a very recent i686->mips-unknown-linux-gnu cross-toolchain available at:http://dev.gentoo.org/~geoman/mips-glibc-crosstools.tar.bz2 if you are too frustrated with building your own.
It includes gcc-3.4.3, glibc-2.3.4 (20041102), and binutils 2.15.91.0.2.

Hi Steve,
thanx a lot.
This tool chain works perfectly for me. Now I can build 2.6.x kernel.
In the past I tried to build a cross tool chain using crosstools. I don`t get any combination of gcc-3.4.x/glibc-2.x.x working. Only the gcc-3.4.x-glibc-2.3.3 combination I could compile without errors, but I couldn't compile a 2.6.x kernel.
Could you please tell me, how you compile the tool chain?
It would be great, if you can provide me a script or a list of patches you applied for building.
Best regards TheNop
Actually, if you just wanted to build kernels, you don't need glibc at all. Just build binutils and then a bootstrap gcc compiler, and you are set. The only reason I messed with a full toolchain at all is so that I can use c++ through distcc.

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.
