Errors in using Intel SGX SSL

SHU_Y_ — Tue, 28 Nov 2017 03:50:07 GMT

Hello.

I'm now developing a simple test sgx application using intel sgx ssl, There are lots of errors after running my makefile.

have built the libsgx_sgxssl.a,libsgx_tsgxssl_crypto.a and libsgx_usgxssl.a,but when i used the "libsgx_sgxssl.a,libsgx_tsgxssl_crypto.a and libsgx_usgxssl.a"

there are some errors:

/home/abc/intel-sgx-ssl-master/sgxssl.1.9.100.99999/lib64/debug/libsgx_tsgxssl.a(tsocket.o): In function `sgxssl_gai_strerror':

/home/abc/intel-sgx-ssl-master/openssl_source/openssl-1.1.0f/crypto/ct/ct_log.c:299: undefined reference to `memcmp'

So how could i solve the problem ?

and how to use the "libsgx_sgxssl.a,libsgx_tsgxssl_crypto.a and libsgx_usgxssl.a," ?

Thanks a lot!!

Hi,

Can you please give some more details? what libraries are you linking (apart from SGX SSL libraries), OS, SDK?

Maybe you've missing linking some SDK required libraries? (sgx_tstdc.a?)

You also can look at test_app makes files to get an example of SGX SSL make files.

Thanks,

Alaa
