After I ran bash build.sh and setup the environment variables, I got the following error:

My platform is macOS Mojave 10.14.3 and python2.7 with virtualenv. PYTHON_LIBRARY and PYTHON_INCLUDE_DIR were set to default. EIGEN3_INCLUDE_DIR and BOOST_ROOT were set to be the path of downloaded and extracted directories. Name for boost_python library was set to the name of BOOST's directory(boost_1_68_0).

Can you give me some advise to solve this problem? Thanks a lot.

The problem is that I've manually disabled the compilers other than gnu gcc in the make script.

1. I'd recommend using a gcc compiler, rather than the Apple clang (install gcc on macOS, or compile on a *nix platform).
2. If it is not possible to use a gcc compiler, try removing the compiler check at core/graph/CMakeLists.txt:13. You may have to eliminate several compilation errors before it compiles.

Thanks for your help. The problem solved after I removed the compiler check at core/graph/CMakeLists.txt and core/algorithm/CMakeLists.txt. Now I get two errors:

One error seems that boost_python cannot be detected. I set the path of BOOST_ROOT to be the path of downloaded and extracted directory from https://www.boost.org/doc/libs/1_70_0/more/getting_started/unix-variants.html#get-boost. Did I do it correctly?

1. The first problem is expected to be fixed now, though I'm not perfectly sure without testing on your compiler.
2. According to the log, the boost library is found without boost_python library in it. You may check the built/installed boost libraries to see if boost_python libraries exist. If they do not exist, you'll have to check your boost building commands; If they do exist, but with a non-default name (libboost_python.so), setting the "name for boost_python library" option helps.
3. It seems that the vital error during your compilation is "Could NOT find OpenMP_C", which means your compiler does not support OpenMP (by default). You should do some research on your compiler to see if you can have the OpenMP support enabled.
