For reasons that I have no control over I am having to compile a Linux 2.6.19 kernel. This kernel has been fiddled with by linksys so upgrading it may or may not be possible. The problem I am having is when I attempt to compile it I am getting an error saying 'PATH_MAX' undeclared in sumversion.c. I suspect that this is due to me having sanitized kernel headers from Linux 2.6.30. One good note is that linksys provided in the tarball a tool chain but I am having issues being able to get the make file in the kernel to use the that tool chain instead of mine. Anyone got any ideas on what I can do?

What do you mean by "having sanitized kernel headers from Linux 2.6.30". Are you saying that you've removed the header files that linksys supplied and replaced them with something else? If so, that's not too likely to compile as they make changes to kernel structures with just about every version. If you're talking about some externel header folder (outside of your kernel source tree), then that's irrelevant to the compilation to the kernel.

No my kernel headers that I used to build glibc with is from kernal 2.6.30 I have not replaced them but I thought GCC will link with whatever it has for its spec. Unless the kernel make file does things differently. Again my question remains even if all this talk of headers is nonsense why is the kernel not building?

What command are you using? What exactly is the error response? If it's a generic type of error, maybe I can help. If it's something specific to gentoo, maybe not.

Hehe I fixed my own issue. Apparently back in the 2.6.1 - 22 kernels sumversion.c did not have a required include in it and it would cause this error on newer compiles for some reason. The file is mising a #include<limits.h> in the header. I added it back in and now it seams to be compiling fine. Thanks for responding tho.

Glad you got it fixed.
