Hi Matthias,

you recently fixed use of the apt cache in gcc-defaults #1104504.
Unfortunately, the new version poses several problems.

A relatively straight forward one is this message during build:

| dpkg-query: error in show format: may not be empty string

It originates from:

| MOD_VER := $(shell dpkg-query -W --showformat='${Provides}' gfortran-$(PV_GFORT) \
|                 | sed 's/.*\(gfortran-mod-[0-9]*\).*/\1/')

In this invocation, ${Provides} is evaluated as a makefile variable. As
it happens to be unset, the empty string is substituted. dpkg doesn't
like that and as a result, gfortran does not provide any gfortran-mod-*.

This is easily fixed by escaping the $ as '$${Provides}'. Fair enough.

The next problem is the additional gfortran-VER dependency. It's implied
as a host architecture dependency and it transitively depends on
binutils:HOST. This is in stark conflict with binutils:BUILD as depended
upon by build-essential. As a result, this dependency is always
cross-unsatisfiable.

If we assume that the modversion does not vary across architectures
(which seems like a valid assumption given that it is scraped from
$(srcdir)/gcc/fortran/module.cc), we may change that to
gfortran-VER:native. Do you agree?

Helmut

fixed both in the VCS.

We believe that the bug you reported is fixed in the latest version of
gcc-defaults, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1107486@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
