python-igraph build failed since r2774

[h0cked]

igraph built was successfully, but it failed when I tried to build the python binding...

Thanks!

We have added a few new parameters to the isomorphism functions recently (in #2762), so it is likely that you have to update and recompile the C core before updating the Python interface.

Hint: we will release 0.6 officially in a few days, so maybe it's easier to wait a bit :)

[h0cked (timobj)]

Thanks for the response! I can wait. What I am doing doesn't not really require the latest version of igraph.

BTW, I did use the latest trunk version to compile both C and python interface. And it gives the same errors.

Thanks again!

[Tamás Nepusz (ntamas)]

Oh, hang on, I think I got it. You have compiled the C core but you haven't installed it before compiling the Python interface, right? The compiler picks up the old include file from /usr/local/include/igraph and not the new one from the freshly compiled C core, and the old include file does not include the new parameters for the isomorphism functions.

The development of igraph has moved to github, so please do not comment on this bug here. You are of course welcome to comment on github, here:
