[klibc] Compilation errors

[Peter Christy]

OK, starting to get somewhere now, but still not out of the woods......

In the traditional Slackware fashion, I'm using a build-script, originally 
found on slacky.eu (IIRC!)

This included the lines:

KERNEL=${KERNEL:-$(uname -r)}

and

KLIBCKERNELSRC=/lib/modules/$KERNEL/source HOSTCFLAGS=$SLKCFLAGS make
KLIBCKERNELSRC=/lib/modules/$KERNEL/source make install INSTALLROOT=$PKG

Now when I compiled my kernel, I added my initials as a suffix (-pc), which (of 
course!) uname -r wasn't picking up! So, you were quite right about the kernel 
headers! Mea culpa!

I amended the script to correct this, but the compilation still fails, this 
time with:

/tmp/SBo/klibc-2.0.2/usr/klibc/../include/errno.h:9:23: fatal error: 
asm/errno.h: No such file or directory

I tried it again, replacing the links to the source with your suggested link:

KLIBCKERNELSRC=`pwd`/../linux/usr/ HOSTCFLAGS=$SLKCFLAGS make 
KLIBCKERNELSRC=`pwd`/../linux/usr/ make install INSTALLROOT=$PKG

but it still failed with the same error.

So I did a locate errno.h, and got this:

/usr/src/linux-3.6.3/arch/parisc/include/asm/errno.h
/usr/src/linux-3.6.3/arch/sparc/include/asm/errno.h
/usr/src/linux-3.6.3/arch/mn10300/include/asm/errno.h
/usr/src/linux-3.6.3/arch/score/include/asm/errno.h
/usr/src/linux-3.6.3/arch/s390/include/asm/errno.h
/usr/src/linux-3.6.3/arch/powerpc/include/asm/errno.h
/usr/src/linux-3.6.3/arch/h8300/include/asm/errno.h
/usr/src/linux-3.6.3/arch/alpha/include/asm/errno.h
/usr/src/linux-3.6.3/arch/cris/include/asm/errno.h
/usr/src/linux-3.6.3/arch/ia64/include/asm/errno.h
/usr/src/linux-3.6.3/arch/avr32/include/asm/errno.h
/usr/src/linux-3.6.3/arch/xtensa/include/asm/errno.h
/usr/src/linux-3.6.3/arch/microblaze/include/asm/errno.h
/usr/src/linux-3.6.3/arch/frv/include/asm/errno.h
/usr/src/linux-3.6.3/arch/arm/mach-bcmring/include/csp/errno.h
/usr/src/linux-3.6.3/arch/mips/include/asm/errno.h
/usr/src/linux-3.6.3/arch/x86/include/asm/errno.h
/usr/src/linux-3.6.3/arch/m32r/include/asm/errno.h
/usr/src/linux-3.6.3/include/linux/errno.h
/usr/src/linux-3.6.3/include/asm-generic/errno.h

Note that last line! It looks as if - again - klibc is looking in the wrong 
place for files, just as it did with unistd_64.h

The kernels I'm using are bog standard ones, downloaded from kernel.org, which 
means they haven't got any "tweaks" that are often applied by some distros. 
Also, I'm running 64-bit, so I don't know if this makes a difference to where 
things go!

I'll have a go at tweaking the errno.h file in klibc to point to the right 
place and see if that helps. Just hope there aren't too many more like 
this....!

Cheers,
