getting about 5 errors from PyClerk on startup and the program crashes after briefly popping up the splash screen

most are unfefined symbol from _hou.so
tbb::internal::throw_exception_v4

and then a final undefined symbol of
tbb::internal::concurrent_vector_base_v3:internal_resize

we're on fedora 15, and I've tried this on fedora 19 as well.
with the same result. and also have tried python 2.6 and 2.7

any ideas what could be happening?

Can you check if your LD_LIBRARY_PATH environment variable is set to anything?
If it is, try prepending $HFS/dsolib to it. In bash, it'd be something like:
export LD_LIBRARY_PATH=“/opt/hfs13.0.198.21/dsolib:$LD_LIBRARY_PATH”

That fixed it! thank you !

Houdini 13.0.228 should have this fixed behind the scenes without the user needing to munge their LD_LIBRARY_PATH. Can you try with that version without changing LD_LIBRARY_PATH?

I had a similar problem and this post helped me out too. thanks
