pyhton-ogre installation on Ubuntu 11.10 Oneiric

Hi!

I'm trying to install python-ogre on Ubuntu 11.10 Oneiric Ocelot, unfortunately it seems there are no precompiled .deb packages
or ppa repositories with pyogre for oneiric.

I tried to build from source following the wikiV4 guide and also using the .sh install script but without success.
The same result using the step-by-step guide for ubuntu prensent in the trunk svn repo.

what am I missing? any hints?

You will need to tell us at what stage the build is failing, check for errors in log.out and post your errors here.

Ok... here is what I get if I follow the wiki guide on a fresh ubuntu installation:

With the previous manual fixes building seems done but the python module cannot be imported and loaded.

Ok.. checked log.out files and I had to install also boost and cmake to build some parts.
anyway when I pass this command:
python python-ogre/BuildModule.py -b ois ogre --usesystem

I get this error:

Then post your log on http://pastebin.com/ and and just include a link here. A summary of where/what step the build is failing at would also be helpful.

I've posted a pastebin url
Unfortunately url and code tags are not allowed for new users!

I think they have had a lot of problems with spam but when it gets to this stage it's just ridiculous. You would be better contacting one of the Moderators on the main forum.

There is the python-ogre developers group but I think you have to wait for activation/approval for your first posts, though even I have trouble posting there.
http://groups.google.com/group/python-ogre-developers

Anyway the link should be something like "http://pastebin.com/wffddeeg";, just post the last part of the link "wffddeeg". Hopefully that is allowed.

Using the SVN Trunk repo and following the WikiV4 guide, the building fails at this step:

python python-ogre/BuildModule.py -g -c ois --usesystem

paste (dot) ubuntu (dot) com (slash) 745638


instead if I use the stable branch v1-6-4 the building fails here:

python python-ogre/BuildModule.py -g -c ogre --usesystem

paste (dot) ubuntu (dot) com (slash) 746001

Ok I think I know what could be happening here. The version of gccxml python-ogre "20091110" is really old and doesn't fully support gcc 4.6 so gccxml is probably built/fudged using the latest it does support (gcc 4.4 if IRC).

First check the version of gccxml in /usr/bin matches the one in <your-build-dir>/gccxml-build directory, i.e. has been installed properly.

Second try using the packaged version of gccxml from Ubuntu:

1) Uninstall the version of gccxml you have installed with python-ogre
cd <your-build-dir>/gccxml-build
sudo make uninstall

b) Install gccxml from Synaptic Package Manager - this appears to be more recent and should support your compiler.
OR
(gccxml from apt works for me so report back before switching to CVS)
Update the gccxml package to the latest CVS version and rebuild.

c) Repeat your -g etc. steps


There also appears to be a packaged version of pygccxml of Synaptic. I wonder if python-ogre builds with this. Let us know how you get on.

dermont thanks for the tips.. it seems I made some progresses but still cannot complete building

this is the giant log:

paste (dot) ubuntu (dot) com (slash) 747386

From your log it looks like you have run out of memory and/or swap space during linking.
Do a google search for "ld terminated with signal 9", maybe for tips on increasing your swap space.

First check this thread, re-arranging the build command for gcc4.6 will dramatically reduce the size of the object files and size of the ogre module. I'm afraid this will mean compiling again.
viewtopic.php?f=3&t=14906

How much memory/swap space does your machine have?

oh well.. it is probably correct.
I'm compiling inside a virtualmachine with just a 1gb of ram to not brake my
current installation with ugly trials.

I'll try to build on a real machine then and give a look to that thread.
thanks again.. I'll let you know about results!

Ok, to clarify the link that I pointed you to was the first post, editing the SConstruct file to ensure the optimization flag is first:

_env['CXX'] = "g++ -O3" <----------------
## Use custom compilier if wanted (things like ccache)


Don't try implementing a unity build this will make things worse. And when you try to build on a real machine then switch to the python-ogre svn branch which uses Ogre1.7.2. The branch you are using the version of Ogre 1.7.0RC1 is old and buggy.

I'm trying on a real machine using trunk svn, 'g++ -O3' modification.
I'm stuck here...

python python-ogre/BuildModule.py -g -c ogre --usesystem

paste (dot) ubuntu (dot) com (slash) 748609

I've tried with gccxml from repos and from cvs but same results...

... purging and reinstalling gccxml from repos seems to fix this problem..

obviously it will break later, we'll see

got it! yeah

here are some draft notes I took for easy reinstalling on another machine,
It is necessary to fix some files, look at the comment in the following lines:

python python-ogre/BuildModule.py -g -c ogre --usesystem
python python-ogre/BuildModule.py -g -c ois --usesystem
python python-ogre/BuildModule.py -b install --usesystem

maybe the wiki should be updated with some notes or fixes.

# purge and reinstall gccxml from repos (tricky, don't ask me why)
sudo apt-get purge gccxml && sudo apt-get install gccxml



it's because you are building the gccxml module, look at the build command for gccxml in environment.py where it installs gccxml overwriting your package version. In your case you do not need build gccxml.


buildCmds = [
[0, "mkdir -p gccxml-build", ''],
[0, "cmake ../gccxml -DCMAKE_INSTALL_PREFIX:PATH=" + PREFIX, os.path.join(os.getcwd(), 'gccxml-build')],
[0, "make", os.path.join(os.getcwd(), 'gccxml-build')],
[0, _sudo + " make install", os.path.join(os.getcwd(), 'gccxml-build')],


There are two config files for the build process:

PythonOgreConfig_system.py -- builds python-ogre against the base libs in /usr or /usr/local or the path you have declared.
PythonOgreConfig_posix.py -- builds python-ogre against the (local) base libs you have built you have built with.

Both config options are configurable, you can edit the paths to libs,gccxml etc. For example you are using PythonOgreConfig_system.py and:

a) have OIS installed from apt so you can just proceed to the the -g -c steps not need to run the (-b) build part.

b) want to run (a) manually:
$ cd <python-ogre-path>/code_generators/ogre
$ python generate_code.py --usesystem
$ cd ../..
$ scons PROJECTS=ois

Warning BuildModule.py adds an extra header include so doing the above means you will have to do a complete rebuild of the module when switching between manual and BuildModule.py.

c) you have base libraries installed in a non standard location:

- Copy PythonOgreConfig_system.py to PythonOgreConfig_lucazade.py
- Edit PythonOgreConfig_lucazade.py and edit your paths as appropriate
- set rpath:
export PKG_CONFIG_PATH=/media/sda8/Libraries/OGRE/sdk/v1-8/lib/pkgconfig
edit config file (global) RPATH or add LINKFLAGS rpath option for module in environment.py
- python python-ogre/BuildModule.py -b -g ogre (no system )

Similarly for the 00-PreReqs.sh script, if you have the latest packaged versions from apt the there is no need to run this.

The previous problem using the packaged versions of libs was with an ancient version of gccxml. If you are interested/feeling brave then it would nice to see if it builds only using/against packaged libs as a first step to getting python-ogre into the Ubuntu/Debian repositories.

Really thanks for the all comprehensive explanations, really useful.
I'll try to follow your advices in my next building.

I'm trying to run python-ogre because I'd like to use Ubuntu at work instead of windows,
now all ogre demos work good, I've tried SampleBrowser and it is quite fast.

The framework I use at work, which employ python-ogre, unfortunately it is still complaning
because it seems to not find the path for python-ogre module.
os.environ['OGRE_PLUGIN_PATH']

any way to set it widely?


############
this is where it dies.. maybe it is useful


def _ogre_bootstrap():
if Model3d._init: return True

plat_name = os.name
fullscreen = str(Config.getint('graphics','fullscreen')).lower() in ('true', '1', 'yes', 'yup')
width, height = Window.size
aa = pygame.display.gl_get_attribute(pygame.GL_MULTISAMPLESAMPLES)
try:
# disable logging.
Model3d._ogreLM = ogre.LogManager()
Model3d._ogreLM.createLog("dummy.log", True, False, True)
# load ogre core and needed plugins.
Model3d._ogreR = ogre.Root()
if os.environ.has_key('OGRE_PLUGIN_PATH'):
Model3d._ogreR.loadPlugin(join(os.environ['OGRE_PLUGIN_PATH'], 'RenderSystem_GL'))
elif exists(join(fmt_libs_dir, 'ogre', 'plugins_' + plat_name)):
Model3d._ogreR.loadPlugin(join(fmt_libs_dir, 'ogre', 'plugins_' + plat_name, 'RenderSystem_GL'))
else:
----> raise Exception('OGRE_PLUGIN_PATH not setted, can\'t load Ogre!') <-----

ok solved also this one..
I had to add to .bashrc some paths

export LD_LIBRARY_PATH="/home/luca/development/root/usr/lib/"
export OGRE_PLUGIN_PATH="/home/luca/development/ogre/lib"

bye bye windows
