Python-Ogre in Windows 7

I have downloaded PythonOgre 1.6.4, and I can't run the demos. please help!

the error message:

Loading library ../../plugins\RenderSystem_GL.dll
OGRE EXCEPTION(7:InternalErrorException): Could not load dynamic library ../../p
lugins\RenderSystem_GL.dll. System Error: No se puede encontrar el m¾dulo espec

Thanks in advance.........

Sadly no i can't help - however I'm just about to get a Win7 machine myself, python-ogre will of course be one of the first things I install so if i can make it work i'll post a solution. If you find out yourself first please tell all!

i had the same problem. follow these steps. This will make it work for a 32bit version of windows 7.

it wouldn't let me upload the pdf here is the link.


I am still having trouble though because i have a 64 bit computer. If anyone else can help me figure out how to run the tutorials. i keep getting the same error.

>>> import ogre.renderer.OGRE as ogre
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
import ogre.renderer.OGRE as ogre
File "C:\Python26\lib\site-packages\ogre\renderer\OGRE\__init__.py", line 10, in <module>
from _ogre_ import *
ImportError: DLL load failed: %1 is not a valid Win32 application.

the problem happens here import ogre.renderer.OGRE as ogre. i cant figure out a way for the path to find this folder i am still new to python ogre. PLEASE HELP !!!!

I have come to the conclusion that it will not work on a 64 bit computer running windows. I saw that some 64 bit Linux machines got it working but i don't know anything about Linux yet. If this is going to work for windows 7 the developers are going to have to remake ogre to run at 64 bits or come up with a way to by pass this error" ImportError: DLL load failed: %1 is not a valid Win32 application." by transferring information at a slower rate on the computers. Hopefully its that latter.

i was wrong i think my issue arrived from putting the ogre folder inside of python 2.6 directory.

nope still not working i did a complete reinstall with new python 2.6.4,directx, the core files and the demos, still getting the same error.

Sorry don't know the answer to your question, you should google your error but as you surmised it's probably a problem with mixing 64bit/32bit libs:
http://www.open-ragnarok.org/forum/view ... ?f=8&t=605

Maybe it's a problem with the python-ogre dll's but have you tried installed/using/ running 32bit python?

There is also a similar on-going thread on the developers group regarding 64bit Windows, maybe you would get a quicker response from one of the developers there.

Well, i can report that I've got my new Win7 machine now, and pythonogre appears fine for me. Some demos aren't working but I think this will be resolved with the 1.7 release ( i'm not compiling from trunk yet )

heres what i did to get it working on my corei5 64, Radeon HD4750

1) get python 2.6 32-bit version
2) downloaded the 1.7 core release from http://sourceforge.net/projects/python-ogre/files/Latest/1.7.SVN%20SnapShot%20--%20UNSTABLE/Python-Ogre-Core-1.7r9326-r1029.7z/download
3) had to manually add python to the PATH environment variable, just added c:\python26;c:\python26\scripts ( right-click 'computer' -> properties -> Advanced system settings -> Environment Variables )
4) extract python-ogre somewhere, open new command-line window - python setup.py install
5) grabbed the demos from the svn - http://python-ogre.svn.sourceforge.net/viewvc/python-ogre/trunk/python-ogre/demos.tar.gz?view=tar
6) extract into the same folder as pythonogre ( i use c:\dev\pythonogre )
7) bobs your uncle - on my system at least

hope its helpful

after installing i've updated the showcase demo to actually run again finally, it looks really dated now though, needs a rework

I just installed on my laptop running Windows 7 64 bits home premium.

Update to bharling instructions:

1) get python 2.6 32-bit version
http://www.python.org/ftp/python/2.6.6/python-2.6.6.msi
Install for all users
Target directory: C:\Python26

2) download the 1.7 release
http://heanet.dl.sourceforge.net/projec ... 1-r1125.7z

3) manually add python to the PATH environment variable, just add c:\python26;c:\python26\scripts ( right-click 'computer' -> properties -> Advanced system settings -> Environment Variables )

4) extract python-ogre for example under C:\Python-Ogre, open new command-line window - python setup.py install

5) demos are already under C:\Python-Ogre\demos
http://ignum2.dl.sourceforge.net/project/python-ogre/Latest/1.7.1/media-1.7.1-r1113.7z

6) Get media files
Unzip media-1.7.1-r1113.7z inside C:\Python-Ogre\ (it will create C:\Python-Ogre\demos\media and C:\Python-Ogre\demos\media_extra

7) Install directX
http://download.microsoft.com/download/8/4/A/84A35BF1-DAFE-4AE8-82AF-AD2AE20B6B14/directx_Jun2010_redist.exe

8) Run the demos:

Fix for Demo_wx:
1) Install wxPython2.8-win32-unicode-py26 from
http://downloads.sourceforge.net/wxpython/wxPython2.8-win32-unicode-2.8.11.0-py26.exe

2) In Demo_WX.py, comment line 41:
# add some fog
#sceneManager.setFog(ogre.FOG_EXP, ogre.ColourValue.White, 0.0002)
