Installing the igraph package for python

I have downloaded the igraph 0.5.4 tar ball for macosx Leopard 10.5.8. When I unpack it and then run:

sudo python setup.py install

I get the following long error message:

Is this a bug or am i doing something wrong?

Best, Thomas

What you have downloaded is only the Python interface to the igraph library. The library itself is written in C, and you will have to install the C core of igraph first before trying to compile the Python interface.

Basically, you have three choices here:

1. Try to make use of the pre-compiled Mac OS X installer of igraph that is found on the PyPI page of igraph.

2. Compile and install the C core first and then try again with the compilation of the Python first. The source code of the C core can be downloaded from the igraph homepage.

3. Install brew and then install the C core of igraph using brew from the command line:

    $ brew install igraph
   

   The above command will download, compile and install the C core of igraph for you, after which you can continue with the compilation of the Python interface.

I had the same problem but the above solution did not work on my mac os X Lion. I couldn't install igraph from the C source code. After looking everywhere I found the solution for the latter posted by Tamas somewhere else. So here is the whole thing that I had to do:

D1. install python2.6

D2. download the source files for the C library for igraph

D3. replace the following 6 source files

src/DensityGrid.cpp

src/DensityGrid.h

src/DensityGrid_3d.cpp

src/DensityGrid_3d.h

with the corresponding files found at

http://bazaar.launchpad.net/~igraph/igraph/0.6-main/revision/2387#src/DensityGrid.cpp

D4. Run the following commands inside the igrpah-0.5.4/ directory

./configure

make

make install

D5. download the source code to install the python extension for igraph

D6. install it running the command from python-igraph-0.5.4

sudo python2.6 setup.py install

and remember to use python2.6 to run it.
