Hi there. I am trying to install Graph-tool on a Linux server with CentOS 6.6, gcc 4.7.2, Boost 1.58.0. I am using this script to run the configure file: export BOOST_ROOT=$HOME/boost_1_58_0 export PKG_CONFIG_PATH=$HOME/cairomm-1.2.0/:$HOME/lib/pkgconfig ./configure --prefix=$HOME --with-sparsehash-prefix=google CPPFLAGS="- I$HOME/boost_1_58_0" LDLFLAGS="$HOME/boost_1_58_0" scl enable devtoolset-1.1 bash configure seems to go well without any abnormal message: checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes checking whether make supports nested variables... yes checking whether make supports nested variables...
