[vtk-developers] VTK Python on Sun

[Andy Cedilnik]

My observations so far:
Yes, it has to do with C++ compiler. When libvtkCommon.so and so on are
build they do not link to libCrun.so. When vtk executable is build it
does. The result is that VTK/Python on Sun using Sun C++ compiler will
not work. I even tried to link libCrun by myself and that resulted in:

Python 1.5.2 (#5, May  1 2002, 11:42:34) [C] on sunos5
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> import vtk
Traceback (innermost last):
  File "<stdin>", line 1, in ?
  File "/space/berk/vtknew/Wrapping/Python/vtk/__init__.py", line 7, in
?
    from common import *
  File "/space/berk/vtknew/Wrapping/Python/vtk/common.py", line 7, in ?
    from libvtkCommonPython import *
ImportError: ld.so.1: python1.5: fatal: relocation error: file
/space/andy/vtk/VTK-bin/bin/libvtkCommonPython.so: symbol
__1cDstdEcerr_: referenced symbol not found

And so on.
