[Paraview-developers] [EXTERNAL] Re: Build error

[Chris Harris]

Hi Alan,

We shouldn't need to link directly to pthreads here, although the will
solve your link error. Looking at your cache it looks like PYTHON_LIBRARY
is set to the static library libpython2.6.a this is probably the root of
the problem can you try changing it to libpython2.6.so.

Regards,

Chris
