Installation (macOS 10.14.6): gcc/clang error of igraph on

[caglorithm]

I'm having installation problems of igraph with the following error, linked to this igraph issue.

clang: warning: libstdc++ is deprecated; move to libc++ with a minimum deployment target of OS X 10.9 [-Wdeprecated]
    ld: library not found for -lstdc++
    clang: error: linker command failed with exit code 1 (use -v to see invocation)
    error: command 'gcc' failed with exit status 1

Solution:

brew install igraph
MACOSX_DEPLOYMENT_TARGET=10.14 pip install python-igraph

thanks for the report!
I'll make igraph an optional dependency since only plotting of the optimised ternary tree depends on it and it is rather heavy-weight dependence.

igraph is now optional dependency. cf. #17 and new release (v0.3)
