Build-Depends on certain architecture

[Daniel Lutz <danlutz@debian.org>]

Hello

A package of mine, `synergy', does compile on every platform
except on hppa. hppa needs at least gcc 3.0. But this version
of gcc seems to have a bug, synergy doesn't compile with it
on hppa. So I need to use gcc 3.2 on hppa.

Now I tried to figure out the correct statements for the
`Build-Depends' field. On every platform, the default gcc
should be used, except on hppa, where gcc-3.2 should be used.

Here's the old field:

  Build-Depends: debhelper (>> 3.0.0), xlibs-dev

And here's the new one:

  Build-Depends: g++-3.2 [hppa], debhelper (>> 3.0.0), xlibs-dev

Is this correct?


Then I will need to change debian/rules accordingly. How should
I test for the architecture in this case?

  dpkg-architecture -qDEB_BUILD_ARCH

or

  dpkg-architecture -qDEB_HOST_ARCH

(I think the second one makes more sense.)
