[Xastir] Segfault on indexing maps

[Tom Russo]

On Sun, Sep 16, 2012 at 06:07:29PM +1000, we recorded a bogon-computron collision of the <edodd at billiau.net> flavor, containing:
> I've been trying to get some maps to show in xastir without success.

You mean you're using a binary provided by the Debian testing repository?  
If that version has the problems you're describing, you're better off building
from source.  There's nothing we can do to fix Debian's package --- it is not
produced or supported by the Xastir group.  Contact the package maintainer
if you really want to keep using that version, but you would be much better
off pitching the package and building from source code yourself.

Assuming you don't mean that you're using a pre-packaged binary, then there
may be some things you can try.

Tigermaps are gone, the server itself was taken down by the Census several
years ago, and it is not coming back. (They may create a new map server some
day, but even if they do it will be a completely new one and will probably not 
work with Xastir without code changes)

OSM should work, but you may be using one of the sets that has moved.  Try
OSM_tiled_mapnik.geo, which is in use by a lot of Xastir users.  If that
also times out then it isn't an issue of a broken URL, and something else
is up with your set-up.

Xastir 2.0.0 is the last formal release we did, but it was done a very long 
time ago and there *have* been changes to the code since then.  It is possible 
that one of these changes would help you.   You would be better off working
from Xastir CVS than Xastier 2.0.0.

This is not an Xastir issue, and won't be the source of your segfault.

You have two choices to fix this:  add the 5.1.25 libraries (you say you
can't find 'em, though) or add the 5.1.29 headers and remove the 5.1.25 headers,
and make sure that configure finds the right matching pair --- you can use 
CPPFLAGS to help with that process if your various DB versions are installed 
in separate locations (e.g. "CPPFLAGS=-I/usr/include/db51" or something 
similar).

But you're right, this isn't the source of your segfualt.

This makes it sound like your GeoTIFF install was not built with proj.4 support.
If you installed libgeotiff from a repository, then you need to check that
it pulled in proj.4 as a dependency.  If not, then your best bet is probably
to install proj.4 and libgeotiff from sources instead --- Xastir will not
work with a libgeotiff that has been improperly compiled.  It should not have
segfaulted, though.

You might try reconfiguring and rebuilding Xastir with the following:
  /path/to/xastir/configure CFLAGS="-O0 -g -fno-inline"
  make && sudo make install

and when it segfaults use "gdb" to figure out where it's crashing.
