Bug#806080: mpich: FTBFS when built with dpkg-buildpackage -A (No such file or directory)

[Santiago Vila]

Package: src:mpich
Version: 3.1-6
User: sanvila at debian.org
Usertags: binary-indep
Severity: important

Dear maintainer:

I tried to build this package with "dpkg-buildpackage -A"
(i.e. only architecture-independent packages), and it failed:

--------------------------------------------------------------------------------

Sorry not to have a fix, as I am reporting many bugs similar to
this one, but I can give some general hints:

* If all the arch-independent packages are dummy transitional packages
released with jessie, the easy fix is to drop them now.
 
* If not, debian/rules should be modified so that the binary-indep
target works in all cases, even when binary-arch is not used (this is
what the "Architecture: all" autobuilder does). For that:
    
* If you are using debhelper, you might want to use options -a and -i
for dh_* commands so that they do not act on packages they do not
have to act.

* Also, if you are using dh, the (independently) optional targets
override_dh_foo-arch and override_dh_foo-indep (for several values
of "foo") may be useful to write a debian/rules which behaves exactly
as desired.


After checking that both "dpkg-buildpackage -A" and "dpkg-buildpackage -B"
work properly, this package will be suitable to be uploaded in
source-only form if you wish (you might want to try it).

Thanks.
