klibc - Nov 2012 - Compilation errors

I've been trying to compile klibc on my system, so that I can have high 
resolution consoles via uvesafb, without conflicting with the NVidia drivers I 
need to use to handle hi-def video.

I have tried versions 1.5.20, 2.0.1 and 2.0.2 all without success.

My system is Slackware64-14.0 running kernel 3.6.3 on an AMD quad core 
motherboard. GCC version is 4.7.1.

My initial problem was that the compilation failed when it failed to find 
unistd_64.h in /usr/src/linux-3.6.3/arch/x86/include/asm/

This is because in kernel 3.6.3, it appears to be in 
/usr/src/linux-3.6.3/arch/sh/include/asm/ -  a small but significant difference.

I overcame this by making a symbolic link between 
/usr/src/linux-3.6.3/arch/sh/include/asm/unistd_64.h and 
/usr/src/linux-3.6.3/arch/x86/include/asm/ , which overcame that problem, but 
is not an elegant solution!

But I am still unable to get klibc to build!

2.0.2 fails with the following error:

usr/klibc/sigsuspend.c:8:31: fatal error: klibc/havesyscall.h: No such file or 
directory
compilation terminated.

whereas 1.5.20 and 2.0.1 fail with similar errors:

klibc-2.0.1/usr/klibc/../include/sys/types.h:28:1: error: unknown type name 
'__kernel_nlink_t'

I am not a programmer, but both these errors look like internal errors within 
klibc to my uneducated eyes.

Any suggestions gratefully received!

You are trying to compile against the wrong headers, let me show an easy way:

get a linux source:
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
cd linux
make defconfig
make headers_install

cd ../klibc/
make  KLIBCKERNELSRC=`pwd`/../linux/usr/

this is fixed in 2.0.1 for recent linux headers.
