Hi,
I'm on a 64-bit RHEL5 (/6) machine and am having trouble installing the
Python bindings. Any ideas of what I'm doing wrong and how to fix it
would be appreciated.
I have igraph itself installed at a prefix of /unsup/igraph-0.6/$(sys),
and I do the following to try to get Python working:
mkdir -p /unsup/igraph-0.6/$(sys)/lib/python2.7/site-packages/
export PYTHONPATH=/unsup/igraph-0.6/$(sys)/lib/python2.7/site-packages/
export PKG_CONFIG_PATH=/unsup/igraph-0.6/$(sys)/lib/pkgconfig
export LD_LIBRARY_PATH=/unsup/igraph-0.6/$(sys)/lib
python setup.py install --prefix=/unsup/igraph-0.6/$(sys)
(The command $(sys) expands to either 'amd64_rhel5' or 'amd64_rhel6'.)
However, when I try to 'import igraph', it says it can't find module
'_igraph'. Furthermore, if I look into the site-packages directory named
above, it's emptyish:
$ tree /unsup/igraph-0.6/$(sys)/lib/python2.7/site-packages
/unsup/igraph-0.6/amd64_rhel5/lib/python2.7/site-packages
|-- easy-install.pth
|-- python_igraph-0.6-py2.7-linux-x86_64.egg
|-- site.py
`-- site.pyc
0 directories, 4 files
This is the case on both RHEL5 and 6.
----------
Interestingly, 32-bit RHEL5 does more:
$ tree /unsup/igraph-0.6/i386_rhel5/lib/python2.7/site-packages
/unsup/igraph-0.6/i386_rhel5/lib/python2.7/site-packages
|-- igraph
| |-- __init__.py
| |-- __init__.pyc
| |-- _igraph.so
| |-- app
| | |-- __init__.py
...
5 directories, 106 files
but it still complains that it can't find the _igraph module. (I have
PYTHONPATH=/unsup/igraph-0.6/i386_rhel5/lib/python2.7/site-packages and
LD_LIBRARY_PATH=/unsup/igraph-0.6/i386_rhel5/lib/.)
Finally, there are _igraph.so files under build/ in the source tree (and
as you can see above, that's present in
------------
I admit that this setup is a bit strange, and it could very easily be
picking up the wrong Python when doing compilation or something, though
I haven't had much problems installing Python modules in the past.
