Re: [igraph] igraph installation issue in Linux server

[Tamas Nepusz]

Hi,

I'm not sure what the compiler complains about here; in my version, refine_equal_to_first in bliss/graph.hh is not initialized to anything, and neither it is in the official tarball of the igraph package.

Can you try updating your compiler to a newer version, or, alternatively, try installing the development version of the R package of igraph from Github? It can be done like this:

devtools::install_github("gaborcsardi/pkgconfig")

devtools::install_github("igraph/rigraph")
