Autoconf

Autoconf

[Marco Gerards]

Hi,

Either I missed some commit and the instructions how to build on the
AMD64.  Below I included the config.log output.  As you can see it
tries to compile the test for the target machine and it uses glibc.  I
think we have to disable the use of glibc for these autoconf tests.
But I am asking to make sure I am not wasting a lot of time by doing
the wrong thing.

Thanks,
Marco

Ah, you have a good machine...

I think so. I guess Jeroen simply has installed 32-bit libraries, right?

Good enough. :-)

It used to work without glibc.  And it should work with glibc...  Urgh
:-/

For now I am using my MacBook to test in grub-install works.  But
grub-install hates me too... ;-)

Yes, and even if you compile the tests with -nostdlib it will search
for -lc, I don't really think there is way to run the tests without
libc. But I don't really see this as a big problem.
