Ada Web Server for Debian - maintainer's notes The Ada Web Server library can use either libopenssl or libgnutls for strong cryptography. This enables support for the HTTPS and other encrypted protocols. Unfortunately there are problems with both libraries. libopenssl is licensed under terms incompatible with the General Public License, while libaws is licensed under the GPL. Therefore, Debian cannot ship binaries of libaws linked with libopenssl. Linking libaws with libgnutls has a technical problem which I haven't been able to correct. The symptom is that both ada2wsdl and wsdl2aws segfault during elaboration. The segmentation fault takes place in the call to gcry_control which is at aws-net-ssl__gnutls.adb:1000.

If you would like to help solve this problem, please send email to aws@lists.adacore.com (I'm on that list, so you don't need to CC me). -- Ludovic Brenta, 2008-06-01 Debian/rules parses debian/control to detect libgnutls28-dev, else libssl-dev and set SSL=[gnutls|openssl|dummy] accordingly. You may override by setting SSL on the command line or in the environment. -- Nicolas Boulenguez , Sat, 16 Aug 2014 04:03:24 +0200
