Looks like the openexr2 beta1 source is up at github: https://github.com/openexr/openexr/branches

A little late to the game, but OMG it's working! Thank you Szymon!

Nuke 6.3v8 / Houdini 12.0.634 on Fedora 14.

rat4nuke now compiles with Nuke7.0 (tested with N7.0v4 and H12.1.185). Edited February 1, 2013 by SYmek

Thank you for your support.

Under Ubuntu 12.04, I'm getting the following error:

undefined symbol: _ZN14IMG_DeepShadow13getWorldToNDCEPK10UT_OptionsR11UT_Matrix4TIfEiib[/CODE]

I'm using Houdini 12.1.77 and Nuke7.0v2.

Any clues?

Thanks in advance!

[symek]

Are you sure you have h12.1 libraries in a path, not h11? These are errors related to functions missing in H11. I haven't seen them in 12.1.185 .

Also Makefile relies on standard houdini environment variables, so the right version of houdini_setup has to be sourced before build.

[Fabiano Berlim]

Thanks for the support Symek!

I don't think I'm doing something wrong. But I can show you.

Just to be sure, let me check variables and versions.

The Houdini 12.1.77 environment has been initialized.
fabiano@fabiano-pc:~$ echo $NDKDIR
/usr/local/Nuke7.0v2/
fabiano@fabiano-pc:~$ echo $LD_LIBRARY_PATH
:/opt/hfs12.1.77/dsolib
fabiano@fabiano-pc:~$ echo $NUKE_PATH
/home/fabiano/Documents/NUKE/plugins
fabiano@fabiano-pc:~$ ls /home/fabiano/Documents/NUKE/plugins
picReader.tcl ratReaderDeep.so ratReader.so
[/CODE]

Then lets execute Nuke.

When I try to load a rat file I get this error.

Could you try current production build (185), I find it very stable, and I suspect some bug related to missing symbols (these are rather new functions). I was pretty sure they exist in all 12.x builds but either they were added after 12.1.77 or they were omitted after initial addition. If 77 is the only build you can work on, you may also edit Makefile commenting out lines 8-10:

#ifeq ($(HOUDINI_MAJOR_RELEASE), 12)
#CXXFLAGS += -DHOUDINI_12
#endif[/CODE]

The only place HOUDINI_12 is used it exactly the one enabling projection matrix metadata support.

[Fabiano Berlim]

Not working. I changed the Houdini version to 185. Nothing. Tried to comment lines in makefile. Nothing.

Tried to setup $HFS/dsolib with ldconfg. Nops!

I think it must be something related to Ubuntu. Is it normal to have $LD_LIBRARY_PATH always empty? Even caching to ldconfig is not working.

As far I remember, you used to work with Ubuntu, right? Why did you change?

Anyway! Thanks a LOT for your support!

[symek]

I haven't seen Ubuntu for a while now, but I don't think it has anything do to what that. Also LD_LIBRARY_PATH is usually empty at least on Centos. You may want to disable the related code at all (lines 247+ in ratReaderDeep.cpp), but this all looks odd. I haven't heard about such symptom and this plug is already used by many people afaik.

[Fabiano Berlim]

Finally solved!

I tried rat4nuke in clean ubuntu install and everything is working. In the other machine the only big diffence is a custom Alembic build. It must be causing some conflict.

I'm really sorry for that.

Symek! Thanks a lot for your time and amazing support! rat4nuke is really amazing! Congratulations!

[symek]

Wasn't alembic linked with older Houdini libs? It looks like. Anyway great you have finally solved it. My support was minimal, but thank you for appriation

ps As to Ubuntu I've switched to Centos because it seems better suited for business usage. The draw back is that it's much worse supported by packagers, so you endup compiling almost everything from scratch.

Mark Visser has kindy updated rat4nuke for Houdini 12.5 and migrated it to github repo, which is a nice thing after all
