Package: src:boost1.53

Usertags: multiarch
You might have heard of this multi-arch thingy. Now it comes to you as
well. For details see http://wiki.debian.org/Multiarch/Implementation.
What?
~~~~~
To facilitate mixing packages from multiple architectures the
dependencies need to either be able to satisfy dependencies of foreign
architectures or be co-installable with itself. For libraries usually
the latter is done. This is mainly useful for packages with a big number
of reverse dependencies or packages involved with bootstrapping a new
architecture. The former case is true for boost. So here we go.
How?
~~~~
You can find a patch attached, that should do most of the work. The
first goal is to get the commonly used shared libraries be Multi-Arch:
same. This is what the patch does. I omitted the python-related
libraries, because they are non-trivial and have fewer reverse
dependencies. Also the python multiarch situation is a bit messy at this
point. The patch succeeds a build and succeeds piuparts. Testing of
building for reverse build dependencies is still needed. This is why I
did not tag this bug report with patch. Nevertheless my patch should
serve as a starting point for a multi arch conversion.
boost1.49
~~~~~~~~~
Since there will likely be a transition from boost1.49 to boost1.53 (or
later) at some point, I suggest not to bother with boost1.49 and just
change boost1.53 before doing the transition. That way issues with the
multiarch changes will be highlighted during the transition.
Problems / Questions
~~~~~~~~~~~~~~~~~~~~
Should there be any questions, feel free to ask me. You can also stop by
in oftc #multiarch to sort things out interactively.
