^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This is non-portable. On Suns, for example, this will produce a
program abort.
It would be better written:
buffer = fl_show_fselector( "extraction", "./", "*.xy", "" );
if ( buffer )
buffer = strdup( buffer );
I don't think this is the source of your problem, however.

This is probably telling you that either the Drawable parameter is not
a valid Window or Pixmap or that the GC of the Drawable does not match
the depth of the Pixmap you are trying to create.

I don't think so. I'd guess that it's somehow involved with the
parameters of your XCreatePixmap() call. As I said above, it's
probably due to a mismatch between the depth of the Pixmap you're
trying to create and the depth of the Window returned by _map->get_win().
Since it's not clear what else is going on in your program,
particularly in the
carte->loadPositionXY(buffer);
function call, it's difficult to know what else to suggest.
Have you run the program in -sync mode? This may tell you more
accurately when and where your program encounters the error. Since X
generally runs in an asynchronous, buffered mode, errors are sometimes
reported significantly later than they actually occur, leading to
various puzzlements.
