Ok, found it: _dl_get_origin tries to readlink /proc/self/exe to find the value
of $ORIGIN, falling back on the (empty) LD_ORIGIN_PATH environment variable
when that fails; I assume it does this instead of using readlink on the value of
AT_EXECFN in auxv due to the possible race condition.

This isn't really a bug in ghc, as it's a system limitation, though I guess for
Debian we could avoid the use of $ORIGIN as we know where ghc will be
installed, though given ghc-stageX are executed during the build that might be
awkward without either re-linking or setting LD_LIBRARY_PATH (or equivalent).

The Rust compiler has the same issue. Without /proc, it won't be able
to find it's shared libraries. I'm not 100% sure, but I guess it's
an issue when using dlopen() to load the libraries afterwards, but I never
bothered to look into the details.

good catch, that was indeed the case and fixed the issue. Thanks!

Downgrading the bug to normal, though I guess you can also close it. The
openjdk packages have the same issue. (But maybe you want to keep it
open to implement a message to the user saying "arg, /proc not mounted,
but we need it, aborting" or some such.)

Hi Holger!

Has the chroot in which you are trying to install /proc mounted?

Without /proc mounted, GHC is unable to find it's shared libraries
and this particular issue shows up.

Well that's correct; you can see $ORIGIN/../terminfo-0.4.0.2 in there which is
where it should be getting libHSterminfo-0.4.0.2-ghc8.0.2.so, but for some
reason your ld.so is not looking at RUNPATH; once it fails to find it on the
system search path it's supposed to then print something like:

 15470:  search

What version of glibc do you have? Have you got any interesting (to ld.so)
environment variables exported or configuration files changed?

Sorry, I removed ghc from my chroot to get the upgrade going, and when I
reinstalled it now the problem has disappeared.

Hi,
I just upgraded my sid system without issue. I also tried installing ghc
in an up-to-date cowbuilder chroot and it all worked. Can you run
`/usr/lib/ghc/bin/ghc-pkg --version` successfully? Please try running
with LD_DEBUG=libs,files and post the output.

Regards,
James
