Build failure against latest libgpg-error

[Ludovic Courtès]

Hi,

Building the latest libgcrypt against the latest libgpg-error appears to
fail:

/bin/sh ../libtool --tag=CC   --mode=link gcc -I/nix/store/lp6g5g4g42lch22vxidi4hzg39xjcg62-libgpgerror-1.8-svn0/include -g -O2 -fvisibility=hidden -Wall   -o version version.o ../src/libgcrypt.la  ../compat/libcompat.la

See http://hydra.nixos.org/build/292506 for details.

BTW, libgcrypt and libgpg-error are continuously built at
hydra.nixos.org, see http://hydra.nixos.org/jobset/gnu/libgcrypt-trunk .  
I can set up email notification of build status changes if you deem it
useful.

Thanks,
Ludo’.
