I have been trying to compile the recent git version of graph-tool against my anaconda python. I do this using sudo ./configure CXX="g++-5" CXXFLAGS="-std=gnu++14 -Wno-unused-local-typedefs" PYTHON="/home/pmj27/anaconda2/bin/python2.7" CAIROMM_LIBS="-L/home/pmj27/anaconda2/include/cairomm-1.0/cairomm" --enable-openmp (if I skip the sudo it won't pick up boost for reasons not quite known to me). I then run "sudo make -j20" followed by "make install". When opening python and importing the module I however get the error message Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/pmj27/anaconda2/lib/python2.7/site-packages/graph_tool/__init__.py", line 3323, in <module> openmp_set_schedule("static", 0) File "/home/pmj27/anaconda2/lib/python2.7/site-packages/graph_tool/__init__.py", line 3320, in openmp_set_schedule return libcore.openmp_set_schedule(schedule, chunk) Boost.Python.ArgumentError: Python argument types in graph_tool.libgraph_tool_core.openmp_set_schedule(str, int) did not match C++ signature: openmp_set_schedule(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, int) My first thought was that graph-tool must be linking against an incorrect version of boost. So, following the advice from other posts, I ran ldd /home/pmj27/anaconda2/lib/python2.7/site-packages/graph_tool/libgraph_tool_core.so .

Does anybody have any ideas what might be going wrong? Best, Philipp -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...
