IDA 8.4: Qt 5.15.2 sources & build scripts – Hex Rays

A handful of our users have already requested information regarding the Qt 5.15.2 build, that is shipped with IDA 8.4.

The Qt sources used by IDA are:

• based on Qt 5.15.2,
• to which the KDE Qt5 patch collection has been added,
• plus a few custom patches/fixes

Rebuilding Qt from source

In order to obtain compatible libs, the simplest way forward is to

• download the full archive – it contains the original 5.15.2 source + KDE patches + Hex-Rays patches
• go to the build/ directory
• type python3 build.py -h

Note: on Windows, that command should be issued from a Visual Studio 2019 command prompt.
