Any idea what I'm doing wrong? I"m running Centos7.5 gcc version 7.3.1 20180303, Python 3.6.3 and even though i've included the cgal directory in the command it can't find it. I get the error below :

checking for exit in -lboost_thread... yes checking for __gmpz_init in -lgmp... yes checking for __gmpz_init in -lgmp... (cached) yes checking whether CGAL is available in /MYINSTALL/release/cgal4.10... no checking whether CGAL is available in /usr... no checking whether CGAL is available in /usr/local... no checking whether CGAL is available in /opt... no checking whether CGAL is available in /opt/local... no configure: error: CGAL library not found.

The command I'm running is:

./configure --disable-cairo --disable-sparsehash --prefix="/MYINSTALL/graphtool2.27" --with-boost="/MYINSTALL/boost1.61/" CGAL_HOME="/MYINSTALL/cgal4.10/" CGAL_LDFLAGS="-L/MYINSTALL/cgal4.10/lib64/ -lCGAL -lCGAL_Core -lgmp -lboost_thread -lpthread" LDFLAGS="-L/MYINSTALL/cgal4.10/lib64/ -Wl,-rpath-link,/MYINSTALL/boost1.61/lib" --with-cgal="/MYINSTALL/cgal4.10"

What I see in the logs are : configure:21200: checking whether CGAL is available in /MYINSTALL/cgal4.10 configure:21236: g++ -o conftest -fopenmp -O3 -fvisibility=default -fvisibility-inlines-hidden -Wno-deprecated -Wall -Wextra -ftemplate-backtrace-limit=0 -DNDEBUG -I/MYINSTALL/cgal4.10/include -pthread -I/MYINSTALL/boost1.61//include -L/MYINSTALL/cgal4.10/lib64/ -Wl,-rpath,/MYINSTALL/cgal4.10/lib64 -Wl,-rpath-link,/MYINSTALL/boost1.61/lib -L/MYINSTALL/cgal4.10/lib -lCGAL -lCGAL_Core -lgmp -lboost_thread -lpthread conftest.cpp -lgmp -lgmp >&5 /opt/rh/devtoolset-7/root/usr/libexec/gcc/x86_64-redhat-linux/7/ld: cannot find -lboost_thread collect2: error: ld returned 1 exit status configure:21236: $? = 1 configure: program exited with status 1

Your CGAL_LDFLAGS is wrong, since you do not seem to have boost_thread installed, or it has another name in your system. -- Tiago de Paula Peixoto <tiago@skewed.de>
