Problem installing BNC V2.12

[apaulson@…]

Hello,

I am trying to install v2.12 of BNC and am getting the following error after performing qmake bnc.pro then make:

bncsslconfig.h:8:29: error: invalid use of incomplete type ‘class QSslConfiguration’
 class bncSslConfig : public QSslConfiguration {
                             ^

I am following the directions given in the BNC Help PDF on page 21 (Linux Systems), using Qt v4.8.5 on Ubuntu 16.04 LTS. Please let me know what I need to do to install and/or use this application on my platform.

Hi, please use the email in this comment; the previous email given above (can't see it) may have been mistyped.

'Secure Socket Layer (SSL)' seems not to be available on your system. Hence, you should install OpenSSL libraries: ​http://doc.qt.io/archives/qt-5.5/opensslsupport.html

leaving a note for future reference:

This feedback was not immediately clear to me since OpenSSL v1.0.2g was installed and working on my system. After a lot of reading and research (the link provided did not answer my question), I determined that I needed to install the SSL developer library, e.g. apt-get install libssl-dev. I also changed the qmake configure command line instruction to:

./configure -fast -webkit -nomake examples -nomake tutorial -openssl -prefix /usr/local/Trolltech/Qt-4.8.5

and this seemed to solve the problem.
