Testing both with OpenSSL and GnuTLS

[Mikael Svensson]

Hello everybody

For my thesis project I need to extract the SubjectInfoAccess extension 
from X.509 certificates. As far as I can tell libmcrypto does not 
support this functionality yet, so I am planning on adding 
certificate::get_subjectinfoaccess() for this purpose.

The problem is that the function must be developed both for OpenSSL and 
for GNUTLS and I do not know how to do this.

How do I first compile libmcrypto using OpenSSL, then test my code, then 
recompile using GNU TLS and test my code one final time?

Is there a configure flag that forces linkage of OpenSSL or GNUTLS?

Regards
Mikael
