Bug#1131724: sol2: please make the build reproducible

[Chris Lamb]

Source: sol2
Version: 3.5.0-2
Severity: wishlist
User: reproducible-builds at lists.alioth.debian.org
Usertags: nocheck
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

Hi,

Whilst working on the Reproducible Builds effort [0], I noticed that
sol2 could not be built reproducibly.

This was because the package contents differ if the tests are skipped
via nocheck; specifically, the .cpp example files are not included if
the tests are skipped, rendering the package unreproducible as it
differs depending on this.

A patch is attached that uses the dh_installexamples mechanism to always
ship these files, but this would appear to conflict with the intention of
the debian/patches/0005-install-example-sources.patch file already in
the package. (I am therefore not tagging this bug as "+ patch", as it is
not strictly complete.)  However, I *do* include it by way of illustration,
and perhaps applying it and removing 0005-install-example-sources.patch
is the way you would prefer to go.
