Using OpenSSL with Qt >= 5.13.1 on Android

Filed under
Android
KDE

If you are building Qt-based Android applications that need network access, you need to take care of bundling OpenSSL yourself. That has always been the case, however with Qt 5.13.1 (or later), there’s a crucial change that might require you to update your OpenSSL bundling. Users of the KDE Android SDK Docker image are luckily not affected by this, but if you have a manual setup this is likely relevant for you.

In order to avoid the interference from incompatible OpenSSL provided by Android, Qt 5.13.1 changed what it expects to be the name of the OpenSSL libraries when dlopen’ing them. Obviously this breaks existing setups if you don’t adapt your OpenSSL build accordingly. And annoyingly that breakage will only show up at runtime in form of failing network access.

  • How to get Microsoft core fonts on Linux

    Linux is an open-source operating system. As a result, it is missing some critical components that users of proprietary operating systems enjoy.

They’re used in many apps, development, and even graphics design projects. In this guide, we’ll go over how to set them up on Linux. Note: not using Ubuntu, Debian, Arch Linux, Fedora, or OpenSUSE?
