Hello, I am trying to compile the git version of graph-tool. I have configured it as follows: ./configure --with-boost=/opt/anaconda/anaconda3 --enable-openmp This returns a configuration summary as follows: ================================================================================ CONFIGURATION SUMMARY ================================================================================ Using python version: 2.7.14 Python interpreter: /opt/anaconda/anaconda3/bin/python Installation path: /opt/anaconda/anaconda3/lib/python2.7/site-packages/graph_tool C++ compiler (CXX): g++ -std=gnu++14 C++ compiler version: 5.4.0 Prefix: /usr/local Pkgconfigdir: ${libdir}/pkgconfig Python CPP flags: -I/opt/anaconda/anaconda3/include/python2.7 Python LD flags: -L/opt/anaconda/anaconda3/lib -lpython2.7 Boost CPP flags: -pthread -I/opt/anaconda/anaconda3/include Boost LD flags: -lboost_iostreams -lboost_python -lboost_regex -lboost_context -lboost_coroutine Numpy CPP flags: -I/opt/anaconda/anaconda3/lib/python2.7/site-packages/numpy/core/include Sparsehash CPP flags: CGAL CPP flags: -I/usr/include CGAL LD flags: -L/usr/lib -lCGAL -lCGAL_Core -lgmp -lboost_thread -lpthread Expat CPP flags: -I/usr/include Expat LD flags: -L/usr/lib -lexpat Cairomm CPP flags: -I/usr/include/cairomm-1.0 -I/usr/lib/x86_64-linux-gnu/cairomm-1.0/include -I/usr/include/cairo -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libpng12 -I/usr/include/sigc++-2.0 -I/usr/lib/x86_64-linux-gnu/sigc++-2.0/include Cairomm LD flags: -lcairomm-1.0 -lcairo -lsigc-2.0 OpenMP compiler flags: -fopenmp OpenMP LD flags: Extra CPPFLAGS: -DNDEBUG Extra CXXFLAGS: -fopenmp -O3 -fvisibility=default -fvisibility-inlines-hidden -Wno-deprecated -Wall -Wextra -ftemplate-backtrace-limit=0 Extra LDFLAGS: Using OpenMP: yes Using sparsehash: yes Using cairo: yes ================================================================================ and the following config.log config.log <http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/file/t495975/config.log> .
