OpenVDB 2.0.0 compiled for H12.1 - sop nodes not visible

[mrWolf]

I am having quite a bit of troubles accessing SOP OpenVDB nodes from Houdini 12.1 after compiling OpenVDB 2.0.

I manage to compile both the Core Library and Houdini Tooklit.

I successfully installed the library here : $HOME/dev/openvdb/

and $HOME/houdini12.1/dso/

contains all the *.so

10212 -rwxrwxr-x 1 alexp artist 10456537 Nov 20 12:52 SOP_OpenVDB_Advect_Level_Set.so*
  856 -rwxrwxr-x 1 alexp artist   876302 Nov 20 12:52 SOP_OpenVDB_Advect_Points.so*
...
  764 -rwxrwxr-x 1 alexp artist   781040 Nov 20 13:05 SOP_OpenVDB_Visualize.so*
  356 -rwxrwxr-x 1 alexp artist   364020 Nov 20 13:05 SOP_OpenVDB_Write.so*[/CODE]

At this point , I thought It would be enough to open Houdini and at the Geometry level I should already be able to access all the VDB_* nodes.

For some reason it's not working for me.

I checked the variable HOUDINI_DSO_PATH using 'hconfig -a | grep DSO ' from my linux (Debian) shell and this is the feedback:

[CODE]
HOUDINI_AUDIO_DSO_PATH := '<not defined>'
HOUDINI_DISABLE_IMAGE_DSO := 0
HOUDINI_DSO_ERROR := 0
HOUDINI_DSO_EXCLUDE_PATTERN := '<not defined>'
HOUDINI_DSO_PATH := '<not defined>'
HOUDINI_IMAGE_DSO_PATH := '<not defined[/CODE]

>'

Which (please correct me if i am wrong) means that Houdini should search for dso's in "@/dso_^;@/dso" by default. Which expands to:

1) "$HIP/dso"

2) "$HOME/houdini12.1/dso" (<---this is where my SOP_OpenVDB_* files are)

3) "$HFS/houdini/dso"

What i tried with no luck:

- copy the files to /opt/hfs12.1/houdini/dso

- edit $HOME/houdini12.1/houdini.env

[append] HOUDINI_DSO_PATH= /home/alexp/houdini12.1/dso/

.. and restart houdini from a new shell.

Nothing seems to work.

Does anyone has any clue about why I cannot access OpenVDB 2.0.0 dso's from Houdini 12.1 ?

Have you tried setting HOUDINI_DSO_ERROR to 1 or 2 to see if the dsos are actually being loaded/failing to load?

Done !

Houdini DSO error on '/home/alexp/houdini12.1/dso/SOP_OpenVDB_Transform.so'
libopenvdb_houdini.so: cannot open shared object file: No such file or directory[/CODE]

So I pointed LD_LIBRARY_PATH to the path where I installed OpenVDB library and now it works great !!!

Thank you for your help Graham !!!
