I am trying to compile graph-tool 2.22. I'm running Python 3.6.2 with pyenv, and have a staged boost 1.6.64 (linked against my pyenv 3.6.2 install). I do not wish to install boost globally, as it may cause conflicts with my system Python (3.5.x). I am running the following commands: ./autogen.sh ./configure CPPFLAGS="-I/home/joe/Research/graphbooze/libs/boost_1_64_0/" LDFLAGS="-L/home/joe/Research/graphbooze/libs/boost_1_64_0/stage/lib -Wl,-rpath=/home/joe/Research/graphbooze/libs/boost_1_64_0/stage/lib" but am faced with the error "configure: error: Could not link against boost_regex ". I am using the configure flags taken from the graph-tool wiki, and am hoping that my include path folder is correct? Boost's lib directory includes multiple libboost_* files, and I have linked 'libboost_python3' to 'boost_python3' as it was previously causing errors. I'm not sure if that could be related to this problem too, but linking libboost_regex to boost_regex didn't solve the problem. I have attached config.log. I am not entirely sure if this is a boost issue or a graph-tool issue -- the boost compile went through without issue. Any help or direction (even if it's just confirming that it's a boost issue rather than graph-tool) would be much appreciated. Thanks, Joe
