I'm trying to compile ipsec-tools-0.7.1 and it fails because it can't find
asm/swab.h even though asm/swab.h exists.

I'm running vanilla-kernel 2.6.29 on Gentoo.  I've brought this up with Gentoo
but it seems that this is a kernel bug.  Please see below response.


nyx ~ # readlink
/var/tmp/portage/net-firewall/ipsec-tools-0.7.1/work/ipsec-tools-0.7.1/src/include-glibc/linux
/usr/src/linux/include/linux
nyx ~ #

So the error comes from /usr/src/linux/include/linux/swab.h
(#include <asm/swab.h>).

On my x86_64 system, /usr/src/linux/include/asm
is a symlink to asm-x86 which in turn does not contain swab.h.
The only asm-* subdirectories below /usr/src/linux/include
that contain swab.h are asm-frv, asm-m32r and asm-mn10300.

I tried touching /usr/src/linux/include/asm/swab.h, but
it's not being used. What actually helped was
"touch /usr/include/asm/swab.h".

Ok, I've investigaged further.
Kernel 2.6.28 had '#include <asm/byteorder.h>' in
/usr/src/linux/include/linux/swab.h whereas
2.6.29 has '#include <asm/swab.h>'. So it's specific
to 2.6.29 and looks like a bug in the kernel sources, no?

Please refer to the bug entered in Gentoo bugzilla for more details.
