You probably were not using GCC 4.2.1. This is a terribly outdated version that has no C++14 support, and hence can't compile graph-tool. Most certainly you used clang, which reports a "gcc version" 4.2.1. Which clang version did you use? Did you compile graph-tool "manually" or did you use a package manager like homebrew or macports? > When calling ./animation_dancing.py offscreen the script causes a segfault. > Apparently when calling show_all at line: > > 108 win.show_all() > > Thanks in advance for any help! > > Best, > marcus > > P.S.
