Failed to build pybind11 - error with eigen matrix template

[Nixgibbet]

Hi,
i'm pretty new in this world and that's why my question seems to sound a bit stupid.

When i clone pybind and try to build pybind11 with make && make install the following error occurs:

/usr/local/include/eigen3/Eigen/src/SparseCore/SparseMatrix.h:1012:3: error: static assertion failed: INVALID_MATRIX_TEMPLATE_PARAMETERS
make[2]: *** [tests/CMakeFiles/pybind11_tests.dir/build.make:258: tests/CMakeFiles/pybind11_tests.dir/test_eigen.cpp.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:379: tests/CMakeFiles/pybind11_tests.dir/all] error 2
make: *** [Makefile:136: all] Error 2

can someone help me ?
Thank you in advanced.
