5 years ago see #212 for the fix (amend CFLAGS in ~/.R/Makevars)
Trying to install igraph on Red Hat Enterprise Linux Server release 7.3 (Maipo) via RStudio, failed.
Note that my ~/.R/Makevars is the following (as directed by my system admin, and it normally works when compiling packages):
CC=gcc -std=c99 CXX=g++ CXX1X=/opt/rh/devtoolset-3/root/usr/bin/g++
The installer output is so long I can't copy it all; here's the bottommost part that remains in the RStudio console:
