----------------------------------------

             Summary: configure.ac doesn't handle the check for OPENSSL_BIO_METHOD correctly
                 Key: ASTERISK-29684
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29684
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/BuildSystem
    Affects Versions: 18.7.0, 16.21.0, 19.0.0
         Environment: CentOS 7 with openssl11 from EPEL
            Reporter: George Joseph


If you use the {{--with-ssl}} option to point ./configure to an alternate openssl implementation, the check for OPENSSL_BIO_METHOD uses the system openssl shared libraries instead of the ones from the path supplied to {{--with-ssl}}.  If the system version is older than the alternate version, HAVE_OPENSSL_BIO_METHOD can get set to 0 instead of 1 which will actually cause compile issues in res_rtp_asterisk.

Oddly enough, the check for OPENSSL itself _does_ use the alternate library.
