PyOgre updated to ogre 0.15 and now using release build

Anything and everything that's related to OGRE or the wider graphics field that doesn't fit into the other forums.

@tisba
Just tried pyOgre last day and was imrpressed. Can you also make bindings for OgreOde?

Here is my SConstruct file. It can run pyste on the files, but fails while compiling the resulting .cpp files.

Code: Select all

import sys

import glob

selected_variant = 'release'
#selected_variant = 'debug'


# Ensure build directory exist (SConsignFile fail otherwise!)
if not os.path.exists( Dir('#build').abspath ):
    os.mkdir( Dir('#build').abspath )

# Store all dependencies signature in a database
SConsignFile( 'build/.sconsign.dbm' )

# scan for configuration options

if ARGUMENTS.has_key( 'gccxml_path' ):
    gccxml_path = ARGUMENTS['gccxml_path']
    replace_map = { 'gccxml_path' : gccxml_path }
    config_in = file( str(File('#tools/gccxml.config.in')), 'r' )
    config_out = file( str(File('#tools/gccxml.config')), 'w' )
    config_out.write( config_in.read() % replace_map )
    config_out.close()
    config_in.close()
    print '%s initialized.' % File('#tools/gccxml.config')

    config_file = file( str(File('#config')), 'w' )
    config_file.write( gccxml_path )
    config_file.close()

Which version of boost and pyste did u used to build the windows binaries?

I'm using 1.31.0 on linux and it appears that there are some constructs not supported on my boost that are generated by your tools/pyste.py script...

New pyogre prebuild package.

Finally done. I did not have the time to do this before going on holidays, so here it is. It includes a major pyste bug fix for virtual function with default arguments (it was hell to track down and fix). This means that you no longer need to specify all the parameters when calling createChildSceneNode :D

The links for download are in the first post of this thread (which I edited). Notes that the lightning and cloth demo still don't work.

I'm also in contact with jpfarias to try and get a linux version! A generated version of the pyste binding (.cpp) is available there for the courageous mind:
http://gaiacrtn.free.fr/temp/pyogre_.tgz

Happy new year :)

You need boost 1.32. The change I made to pyste to fix the virtual function default argument bug requires new-style polymorphism. It's a new feature of boost.python 1.32. It also speeds up the execution since you only go through python interpreter when the virtual function is actually overridden in python...

For pyste, the pyogre cvs version in pyogre/tools/Pyste is the one to use. It contains many bug fixes which are required to get pyogre working (It seems to be the first project to push it so far).

Hi!

I've modified your .cpp files so that they would compile on linux. Many changes were needed to make them compile clean.

Most errors were about forward declaration of some classes, and those were solved by just inserting some #include's on the files.

Other errors were about the STL becuase gcc STL on Ogre is different than MSVC STL, so, I just removed the references to hash_map and hash_compare on the .cpp files to make them compile.

Another one I can remember now was about trying to reference some protected classes. I also removed those references from the cpp files.

After removing the errors I've got to compile the files and made the .so file, which was a 28MB file. I've tried to run the camera track demo but it fails after loading some plugins, I'll post the error message later cause I'm recompiling OGRE right now.

Well, I think we are close to make things work.
