Hello all,
 +
As part of the plan to fix the PR1.2 SDK dependency issues in the
 +
autobuilder [1], we plan to upgrade the Debian devkit in the Fremantle
 +
autobuilder to the Squeeze version [2] (from the current etch one), and start
 +
using "improved shlibdeps" [3] (a.k.a. .symbols files) to version
 +
dependencies on a much more granular basis (minimal required version of
 +
libraries will be calculated per symbol instead of per library). We plan to
 +
ship .symbols files for most of the SDK libraries [4].
 +
 +
This means that packages built in the PR1.2 SDK using no PR1.2-introduced
 +
functions will work on a PR1.1 device and even on a 1.0 device.
 +
 +
Unfortunately, this approach doesn't include Qt packages as there are more
 +
problems to that, but we hope the Qt API to be more stable in future
 +
releases.
 +
 +
Of course, upgrading to Squeeze _will_ cause compatibility problems to some
 +
packages. We have been rebuilding many of them in a test environment [5, 6]
 +
and analyzed the common issues -- in fact, we have talked to a few
 +
maintainers about those. If your package doesn't build when we move the
 +
autobuilder to Squeeze and you don't know how to fix it, don't hesitate to
 +
ask. We find that most of the compatibility problems are caused by stricter
 +
checks, and that is always a Good Thing (TM).
 +
 +
If you want to swap your local SDK to squeeze, you have to
 +
# Install the squeeze devkit from [2]
 +
# Replace debian-etch devkit with debian-squeeze
 +
# apt-get install maemo-sdk-symbols cdbs man-db dpatch
