Re: [igraph] f2c compile error in trunk

[Tamas Nepusz]

Dear Paul,

If you can, try compiling igraph with ./configure --with-external-blas
--with-external-lapack --with-external-arpack which should eliminate the
dependency on a locally compiled f2c. (Of course you need an external
BLAS/LAPACK/ARPACK library for this). Also, can you give more
information about the platform on which you are trying to compile
igraph? I couldn't reproduce the error on my Ubuntu machine so I suspect
it's something platform- or distribution-specific.
