I should have replied to this e-mail instead of the other in the
thread, apologies for the replay, but this e-mail is better context.

Applied, thanks.  If you can write some unit tests for the arch
installer, regressions will be easier to prevent in the future.

ROS uses a modified version of PCL and swig-wx.  As you are on Arch,
there currently is no packaging for this alternate versions.  Most
system dependencies are equivalent, but PCL shares message data
structures and thus requires alternate build flags to be compatible
with ROS.

The trees that we use to build various system dependencies within our
installation prefix can be found here:


I don't know of the correct way to deal with this on Arch.  swig-wx
will disappear in Groovy and so is a transitional issue.  The PCL
issue is permanent with the 1.x codebase.

AFAIK, the opencv should be compatible, though ROS packages that
explicitly depend on 'opencv2' may need this dependency to be removed
(this is a deprecation/migration issue).

I've started a section in the Migration guide here:

Same as above
