Bug#698924: dpkg: cannot build package from source - libc missing dependency information

[Michal Suchanek]

Package: dpkg
Version: 1.16.9
Severity: important

Hello,

I tried to build the X server and I get this:

dpkg-shlibdeps: error: no dependency information found for
/lib/libc.so.6 (used by
debian/xserver-xorg-core/usr/lib/xorg/modules/extensions/l
ibdri2.so)

I suspect that the fact I installed and removed armel libc on armhf
system may be relevant.

I bootstrapped this system using debootstrap.

Well there's really not enough information here to know what went
wrong, but I have a really hard time seeing this as a dpkg problem.

Do you have libc6-dev for the target architecture? Actually why do you
have a /lib/libc.so.6? that should be on a multiarch path, did you
build a local libc that got installed there while bootstrapping? If so
then you'd need to remove that and then close this bug report. :)

Thanks,
Guillem

Yes, I really wonder what info should I collect in such case.

The problem really is /lib/libc.so.6 unowned by any package which is not
immediately obvious from the dpkg-shlibdeps output.

Thanks
