Hi everyone,
I am trying to compile a HDK plugin I have found online (more precisely, the SOP_Dijkstra_Creator here: http://forums.odforce.net/index.php?/topic/14407-dijkstra-pathfinding-with-python/page__st__12 [forums.odforce.net], I have uploaded a copy here), but I am having some difficulties with the compiler itself.

The installation of VC2008 and the SDKs needed for compiling under Windows went fine as I can compile the SOP_Star example without problems using hcustom.

When I try to compile the aforementioned code, though, it tells me that it can't find the “GB/GB_ElementTree.h” among the includes - I've actually checked and in toolkit/include there's no GB folder at all. Why is that? Have they been deprecated? I've found no information online whatsoever.

Thanks for helping -

Have you checked http://www.sidefx.com/docs/hdk12.5/hdk_changes.html [sidefx.com] and/or http://www.sidefx.com/docs/hdk12.5/hdk_ga_porting.html [sidefx.com]?

GB was the base of the geometry library in Houdini 11.1 and before. It was replaced with GA in Houdini 12.0. Porting may be quite difficult if you're not familiar with the code. Also, we've deprecated some more in Houdini 13, so once you've gotten it working, you may still have a few hundred deprecation warnings when you try to build it for 13.

Also, there'll be a FindShortestPath SOP in Houdini 13, if you can wait until October 31st. :wink: If that HDK plugin is the one I think it might be, FindShortestPath should even have a similar workflow as an option, among many other options.
