[Thuban-list] (Still) No geodata output

[Jonathan Coles]

this appears to be a library problem. if you are compiling Thuban you
have to be careful which version of gcc you use. it must be the same
version that was used to compile the wxWindows libraries. my bet is that
Thuban crashes when it tries to draw the polygon layers using the proj
library. there is some C++ code included with Thuban which calls into
wxWindows code and if the compilers are not the same then the name
mangling will be different.

if you want to test this theory try doing this:

in file Thuban/UI/renderer.py on line 135 comment out the call to
self.draw_polygon_shape() and add "pass" so that the "if" block looks
like this:

            if shapetype == SHAPETYPE_POINT:
                self.dc.SetBrush(brush)
                self.dc.SetPen(pen)
                self.draw_point_shape(layer, i)
            else:
                pass #self.draw_polygon_shape(layer, i, pen, brush)


when you compile/run Thuban you should be able to load the
iceland_sample.thuban file. All the information about the session should
appear in the session tree but none of the polygon layers will be
visible.
