Linux Pybind11 'build check -j 4' error

After installing Pybind11 for linux, I run the command -

make check -j 4 as mentioned in the document - http://ift.tt/2jFazeE

I get the below errors -

make[3]: * [tests/test_cmake_build/CMakeFiles/test_subdirectory_embed] Error 1 make[2]: * [tests/test_cmake_build/CMakeFiles/test_subdirectory_embed.dir/all] Error 2 make[2]: *** Waiting for unfinished jobs....

make[1]: * [tests/CMakeFiles/check.dir/rule] Error 2 make: * [check] Error 2

I am not sure what this means or how to fix it. Any help is appreciated.

Below is the complete log of the output I get when I run - make check -j 4
