Re: [igraph] igraph-help Digest, Vol 62, Issue 6

[Tamás Nepusz]

Hi,

I fixed the brew formula so it now provides an extra option to build igraph 
with both 32-bit and 64-bit versions in the same library. A few changes have to 
be made to /usr/local/Library/Formula/igraph.rb until these changes are merged 
into Homebrew. You can find the necessary changes of igraph.rb here:

https://github.com/ntamas/homebrew/commit/8fb6084fa44d946b59d016a026af3caab77041bb#diff-0

Once you added these extra lines, uninstall the previous version of igraph and 
reinstall the new version:

brew uninstall igraph
brew install --use-gcc --universal igraph

--
