QT license for development with arcgis runtime for Qt

matuskajba — Mon, 11 Jun 2018 13:18:49 GMT

According to this article: https://doc.arcgis.com/en/appstudio/create-apps/licenseappstudio.htm you need Qt SDK license if you wish to charge users for your app, or if you want to include C++ extensions and advanced tools. There is also written this:

"In some cases, the licenses are free but still require you to acknowledge the use of different components".

And I would like to know in what cases are licenses free (I assue this is open source version of Qt SDK) and in what case I have to buy Qt SDK license.

And I have quite the same question about using ArcGIS runtime for Qt. Do I need a commercial Qt license or can I use LGPL version of Qt?

Hi Matus,

You will need a Qt Commercial license if you plan to use their local compilers that come with the Qt SDK (from The Qt Company) to compile your application, regardless of whether you used AppStudio or just the ArcGIS Runtime SDK to build it. You will need to Commercial version, not the open source version.

I hope this helps?

Thank you, that is really helpful. Just to be sure, this means, that if I choose to use Visual Studio compiler, I can use open source version of Qt SDK in both cases?

You can use the VS compiler, but if you are going to put that app that you compile into 'production', you need to buy a Qt commercial developer license. You can purchase these at a discount from Esri as well.
