It does not seem to pick up the boost::coroutine library like that yet. Is this an issue of boost not being correctly linked to Python or an issue of ./configure not finding the correct file? Also, how do I pass multiple CPPFLAGS? My current command is (I have run it without the py2cairo instructions to see if that caused the problem, it doesn't): ./configure CPPFLAGS="-I/home/pmj27/anaconda2/pkgs/py2cairo-1.10.0-py27_2/include/" LDFLAGS="-L/home/pmj27/software/boost1.60/lib" CPPFLAGS="-I/home/pmj27/software/boost1.60/lib" CXX='g++-5' -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...
