As mentioned in our previous blog post, the Windows download of 10.2.5 could only be used with Qt SDK 5.4.0 due to binary incompatibility between 5.4.0 and other versions of the Qt SDK. This problem only affected Windows.
Today, we re-released ArcGIS Runtime SDK 10.2.5 for Qt on Windows, rebuilt and retested atop Qt 5.4.1. This new download replaces the download made available last week. It incorporates the fixes in Qt 5.4.1 and thus avoids the incompatibility problem.
A documentation refresh will arrive later this week with updated System Requirements.
Here’s to your success in building great ArcGIS apps with Qt and QML!
