is there any way run fortran code in sgx

Hello，
I have a fortran demo code,only impl add function(https://github.com/z1queue/fortran_demo.git).
then use " cargo test -- --nocapture" can get the correct result in unit test

now i want to take this function in sgx, so i update the samplecode/hello-rust(https://github.com/z1queue/hello-rust.git) in v1.1.1, it compilate successful but return wrong result,it seem the fortran code not work(result is initialize value).

Can you give me some suggestion about this?

Reproduce the standalone fortran_demo add function with `cargo test -- --nocapture`, then compare it with the modified `samplecode/hello-rust` in v1.1.1. Trace the function’s result in the SGX sample and document what causes the initialized value instead of the expected result; done means the Fortran function works correctly in SGX or the limitation is clearly explained.
