Bug#838327: dune-pdelab: FTBFS in testing (error: cannot convert 'mem_usage_t*' to 'GlobalLU_t*')

[Santiago Vila]

Package: src:dune-pdelab
Version: 2.4.1-1
Severity: serious

Dear maintainer:

I tried to build this package in stretch with "dpkg-buildpackage -A"
(which is what the "Arch: all" autobuilder would do to build it)
but it failed:

WARNING: could not find module dune-alugrid,
       module is also unknown to pkg-config.
       Maybe you need to adjust PKG_CONFIG_PATH!
       dune-alugrid is suggested by dune-pdelab
Skipping dune-alugrid!

Seems a GCC 6 related problem.

Thanks.
