Re: compilation problem with kernel 2.6.15

I downloaded the exact tools and followed exact procedure suggested in http://www.linux-mips.org/wiki/Toolchains#Prologue. But while trying to cross compile the kernel 2.6.15 got the following error:

  (root@Jamuna:/home/ssf/bdcom/linux-mips-kernels/linux-2.6.15)# make O=/home/ssf

  can anyone suggest me what is the problem here?

  Thanks in advance,

This means a new error check in gcc has found a latent kernel bug.

It is also sometimes the case that a new linux kernel finds a latent gcc
bug.

Note, in general, key parts of linux such as the kernel, glibc, and gcc,
often have such heavy dependencies on each other that you can not pick
and choose random versions. If you want to use a particular kernel
version, then there are often particular glibc and gcc versions you
should use with it, otherwise you are likely to run into trouble.

This link:
http://www.linux-mips.org/wiki/Toolchains#Prologue
recommends gcc-3.4. And if you follow the "recommended" link to
http://www.linux-mips.org/wiki/GCC
it specifically recommends against use of gcc-4.1 for compiling the
linux kernel, as this hasn't been well
 tested yet.
