Re: [infomap-nlp-users] infomap-build crashes on 64 bit machines

[Scott C. <ced...@gm...>]

Hi Xiaoyi,

   Yes, this is a known issue with Infomap on 64-bit machines.  I
believe it stems from the linear algebra library that Infomap uses to
perform Singular Value Decomposition (SVDPACKC).

   I'd like to get around to fixing this eventually... if anyone out
there has a fix, please chime in.
