vtk5, tcl, cocoa, and x11 troubles

[jjstickel@…]

This is a bit convoluted, but please bear with me. First of all, vtk5+x11 (using macports x11 libs) produces a bus error for me on Tiger when I try to run any VTK program (c++ compiled or wrapped script). I think this is due to mixed use of macports x11 libraries with apple opengl. It works OK if I use apple X11, but I have not figured out how to force that using macports.

Next I tried using cocoa rendering (-x11). However _{the tcl wrapping of vtk using cocoa does not support all features, most notably interaction. Please see:}

The solution is to use x11 for both tcl/tk and vtk, but as noted above this fails on Tiger.

Luckily, python and cocoa rendering seem to work fine together.

Suggestions/requests:

1. I have provided a patch to the portfile that provides a tcl variant. Since tcl does not fully work without x11, I think this is useful.
2. Perhaps the x11 variant should be forced, or at least recommended, if the tcl variant is selected.
3. I would appreciate any help getting x11 rendering to work on Tiger.

adds tcl variant

OK, I was able to adjust the Portfile to use apple X11 (see attached 2nd attached portfile patch). Now +x11 works fine for me. However, there is something else strange that I encountered: I vtk fails to build with +x11 -tcl +python, with the error:

[ 68%] Building CXX object Graphics/CMakeFiles/vtkGraphicsPythonD.dir/vtkMultiBlockMergeFilterPython.o
ld: Undefined symbols:

However, +x11 +tcl +python works fine, as does -x11 -tcl +python.

adds tcl variant AND forces apple x11

[(none)]

A lot of this was resolved by ticket #19111. I am still having trouble with the x11 and opengl libraries (on Tiger), but I will report that separately.

This ticket can be closed.
