I'll post here about what I'm finding. eudev fails since SO_SNDTIMEO
isn't defined. This comes from asm-generic/socket.h which asm/socket.h
include.

The file:
ppce300c3-poky-linux/eudev/3.2.8-r0/recipe-sysroot/usr/include/asm-generic/socket.h
isn't included.
if I put:
#include <asm-generic/socket.h>
at the top of log.c it will build, everything else doesn't.
Debugging with gcc -e shows its including a different 'interesting' file.
My build has a
build/tmp/work/ppce300c3-poky-linux/eudev/3.2.8-r0/recipe-sysroot-native/usr/lib/powerpc-poky-linux/gcc/powerpc-poky-linux/9.2.0/include-fixed/asm-generic/socket.h
which looks totally wrong when I compare it to the real asm-generic/socket.h.
Why this is in the toolchain I don't know and I'll have to investigate further.
I worry it depends on which MACHINE you have set when you build
gcc-cross-powerpc.
So we have some progress/a lead but more to be done.
Cheers,
Richard
