gcc error on install.

I'm trying to get pyogre up and running for the first time on linux. I have checked out the latest sources, but when I run 'python setup.py build' I get the following:

running build
running build_ext
building 'pyogre._ogre' extension
['pyogre/ogre/ogre.i']
skipping pyogre/ogre/ogre.i
gcc -pthread -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -fPIC -I/usr/local/include -I/usr/local/include/OGRE -I/usr/include/python2.4 -c pyogre/ogre/ogre_wrap.cxx -o build/temp.linux-i686-2.4/pyogre/ogre/ogre_wrap.o
gcc: cannot specify -o with -c or -S and multiple compilations
error: command 'gcc' failed with exit status 1


Here's my gcc version:


gcc (GCC) 3.3.5 (Debian 1:3.3.5-8ubuntu2)


I'm confused. Any help would be appreciated.

What version of swig are you using? (swig 1.3.27 required)
swig -version

The "skipping pyogre/ogre/ogre.i" seems to suggest that the swig step has already been run.

Check if the wrapper files from (pyogre-1.0.6-0 or trunk)/pyogre/ogre exist. If so:

- run 'setup.py clean'
- manually remove the wrapper files from (pyogre-1.0.6-0 or trunk)/pyogre/ogre
ogre_wrap.cxx
ogre_wrap.h

- renun 'python setup.py build'.


You should see something like this:

running build
running build_ext
building 'pyogre._ogre' extension
swigging pyogre/ogre/ogre.i to pyogre/ogre/ogre_wrap.cxx

swigging pyogre/ogre/ogre.i to pyogre/ogre/ogre_wrap.cxx
swig -python -c++ -modern -Ipyogre/ogre -I/usr/local/include/OGRE -o pyogre/ogre/ogre_wrap.cxx -outdir pyogre pyogre/ogre/ogre.i


Report any errors from the swig step.

Thanks for the reply.

I'm using the newest swig, version 1.3.28.

I removed those two files, ran 'setup.py clean' and then ran 'setup.py build' again. Same thing:

I don't see any errors with swig.

Sorry, both pyOgre 1.0.6 and trunk currently only work for Ogre 1.0.6 (1.0.7 should compile though hasn't been tested).

Looks like your using OGRE 1.2.0RC1 / Ogre Dagon.

Thanks Dermont, that seemed to be the problem. Now I am getting PtrException errors whenever I try to run any of the pyogre examples. I think it is from the version of swig I am using (1.3.28), so I'm going to downgrade to 1.3.25 and wait another 2 hours building..

I'll let ya know how it goes, thanks for the help.

Use swig 1.3.27, you may encounter problems with 1.3.25.
