Compiling ogreforests on Linux

Hi guys,

I've been trying to get Python-Ogre running on Linux again in hopes I can have it as a supported platform for MV3D, however, I've got everything going except the ogreforests module which MV3D uses for grass. Here's the error I get when trying to generate code:

Has anyone seen that before or know how to resolve it? I'm running Python-Ogre trunk and followed all the other build steps with no problem. I've got this on Ubuntu 11.04 / 64bit with gcc 4.5.2.

Thanks,

Mike

In python-ogre/code_generators/ogreforests/generate_code.py try removing the define for 'WIN32'.


#'WIN32',

defined_symbols = ['OGRE_NONCLIENT_BUILD', "GCCXML_BUG", '__PYTHONOGRE_BUILD_CODE' ]



Awesome!! That worked. Thank you for the help!

Mike

Oops, spoke too soon. It built but doesn't import.

I could probably get away with disabling grass on Linux, but it would definitely be nice to get it working.

Thanks,

Mike

Sorry I'm not sure why you are encountering the RuntimeError for Ogre::MovableObject. The only way I've been able to simulate this is by not importing the ogre module first - but you are already doing that. I take it the demos have the same problem.

I don't think removing the windows define has anything to do with this. What version of python-ogre / pygccxml / gccxml / ogre are you using?

I'll take another look, you could try raising a bug report on the sourceforge tracker or waiting for one of the developers to comment.

I don't think removing the windows define has anything to do with this. What version of python-ogre / pygccxml / gccxml / ogre are you using?

Yeah, I am pretty sure it's unrelated to the other problem as well.

python-ogre from svn rev 1150, pygccxml from svn rev 1856, gccxml from CVS maybe tag D2011.05.01.04.00.00, ogre 1.7.2. I used the LinuxBuildV4 wiki page except with trunk of python-ogre.

I'll file a bug report. I tried re-generating code for ogreforests and that didn't help the problem. The demos for it give the same error.

Thanks,

Mike

If you haven't already try cleaning out the ogreforests cache/wrapper code/object files and re-generate/rebuild.

1. delete code_generators/cache/ogreforests_r2719_cache.xml
2. clean out the wrapper code/object files
generated/ogreforests_r2719
build_dir_2.7/ogreforests_r2719

This ogreforests moudle already has a dependency to the ogre module and runs OK here (32 bit machine).

mb.register_module_dependency ( environment.ogre.generated_dir )


Has anyone else built the ogreforests moudle on Linux and/or run into similar problems?

I'll try a build early next week with the version of gccxml you are using though I think that's pretty much what I'm using.

Sorry I tried a fresh rebuild but couldn't reproduce the problem. I've seen this before with the OgreOde module and thought it was down to the version of gccxml; which apparently it wasn't.

Since a couple of developers have been on the forum since you posted the original message I'm assuming that someone has contacted you directly regarding this.

Not yet. I'm still having the problem.

I'm going to try completely rebuilding the generated code again tonight. I tried that before but didn't wipe out the file from code_generators/cache. I've also still got to file a bug report.

Thanks so much for your help.

Mike

No change after rebuilding the generated code unfortunately.
