After compile finished I used CMake to build the application then used macdeployqt to make a Mac package.īut when I try my package in a VM which contains outdated OpenSSL libraries (0.9.8y), I saw that application uses the system libraries, not the updated ones (1.0.2c). configure -linked-openssl -prefix ~/Qt5.5.0-RC I followed the instructions on this page and updated my OpenSSL packages using Homebrew and put them to the system place /usr/bin/openssl so system use them as default OpenSSL libraries. OpenSSL has been around a long time, and it carries around a lot of cruft. However, you should perform a make clean to ensure the list of objects files is accurate after a reconfiguration. I read through these forums and other places and decided to update OpenSSL libraries on my Mac then linking them to Qt so when I make a distributable package it comes with updated OpenSSL libraries. OpenSSL 1.1.0 and above performs the dependency step for you, so you should not see the message. It may not be a big security issue, but it creates SSL errors when browsing internet. Most of you know that OpenSSL libraries on Mac OS X are outdated.
