Hi MoonHasSevenColor,

Thanks for reaching out.

We found an external repo (not owned by Intel) that may assist your use cases to use Eigen in SGX projects, make sure the listed files below are all visible during compilation.

• shim.hpp,
• Eigen
• emmintrin.h
• mmintrin.h
• mm_malloc.h
• xmmintrin.h

Meanwhile, you can check the Pass-by-value and Pass-by-reference to pass the Eigen C++ parameters. Here is also a reference for Writing Functions Taking Eigen Types as Parameters.

Hope that the information provided is useful for you. Please let us know if you have any questions.

Regards,

Aznie
