I was compiling graph-tool with gcc8.2 and I was getting this error then I used gcc7 with this command line:

./configure CPPFLAGS="-I/Users/anaconda2/pkgs/pycairo-1.18.0-py27h4d1f301_0/include -I/usr/local/include" -with-cgal=/Users/anaconda2/pkgs/cgal-4.12-py27h8634a1c_1 --prefix=/Users/anaconda2 LDFLAGS="-L/usr/local/lib" CC=gcc-7 CXX=g++-7

It got compiled but again when I import graph-tool in python, I receive this error message:

>>> from graph_tool.all import *

What can be the problem now?

Thanks again.
