Re: [gentoo-embedded] Advantech PCM-3350, linux box, boot from CF

[Goran Kavrecic]

OK, I emerged crossdev-0.3, started 'crossdev.sh --arch=i586'. It
downloaded 4 modules(linux-headers-2.4.19-r1, binutils-2.14.90.0-r6,
gcc-3.2.3-r3, glibc-2.3.2-r3), copyied to
/var/tmp/portage/crossdevbuild, then started stage2...stage5, started
'Configuring sys-libs/glibc-2.3.2-r3 (full)...' and the following error
came out.

---
checking for egrep... (cached) grep -E
checking installed Linux kernel header files... TOO OLD!
configure: error: GNU libc requires kernel header files from
Linux 2.0.10 or later to be installed before configuring.
The kernel header files are found usually in /usr/include/asm and
/usr/include/linux; make sure these directories use files from
Linux 2.0.10 or later.  This check uses <linux/version.h>, so
make sure that file was built correctly when installing the kernel
header
files.  To use kernel headers not from /usr/include/linux, use the
configure option --with-headers.
 
 * glibc failed to configure!

I suppose 2.4.19 is newer than 2.0.10. Am I making something wrong?

Best Regards & Happy New Year,
