[LinuxPPS] Confused with ppstest.c on 2.6.31

[Luca Bertagnolio]

Hi all,

been updating my Gentoo test machines with a 2.6.31-gentoo-r6 kernel with the
latest patch from Rodolfo.  Everything compiles nicely, and I get the modules
that load OK in the kernel.

On the other hand, I am running into issue in compiling the silly ppstest.c
software found in the Documentation directory in the kernel sources.

Irregardless of whether I include the linux/asm/asm-generic links in
/usr/include
I cannot seem to get ppstest.c to compile.

If I don't have the links this is what I get:

tix pps # make
cc -Wall -O2 -D_GNU_SOURCE -I . -I ../../include/ -ggdb    ppstest.c
-o ppstest
In file included from /usr/include/asm/types.h:4,
                 from ../../include/linux/types.h:4,
                 from ./timepps.h:27,
                 from ppstest.c:8:
../../include/asm-generic/int-ll64.h:11:29: error: asm/bitsperlong.h:
No such file or directory
make: *** [ppstest] Error 1

If I have the links this is what I get, much longer yet still
meaningless to my eyes:

tix pps # make
cc -Wall -O2 -D_GNU_SOURCE -I . -I ../../include/ -ggdb    ppstest.c

make: *** [ppstest] Error 1

Was ppsetest.c tested with the new patches?  Or is this something local to
my specific setup?

I am using glibc 2.10.1 with timex.h patched to add NANO and TAI, though
I don't believe that there is much relationship here, with the apparently
simple compilation of ppstest.c...

Any hints for me?

Thanks, Luca
