Use GMP,PBC library in Enclave

Hi,

GMP, PBC library includes many cryptographic primitives. But How to use the libraries in the enclave.

I tried https://github.com/intel/sgx-gmp.git to install the gmp library. However, it reports error:

/opt/gmp/6.1.2/include/sgx_tgmp.h:474:12: error: ‘std::FILE’ has not been declared
474 | using std::FILE;

I observed that in the git https://github.com/intel/sgx-gmp.git , there is a mini-gmp. Is it available?

Thanks very much!

Hi Martin,

Which installation step are you getting this error at? Please send over the command you ran.

Also, mini-gmp is part of GNU-MP library

Sincerely,

Sahira
