Building DeepSkyStacker:

To work on the current development codebase (for DeepSkyStacker 6.1.2) which uses a VS solution file called DeepSkyStacker.VS2022.sln, you will need to install Visual Studio 2026. For earlier code versions either VS2019 or VS2022 will work.

If you open a DeepSkyStacker solution file for 6.1.1 or earlier releases, please do not accept VS2026's offer to upgrade the build environment the first time you open the solution file.

In addition to Visual Studio, you will need to install Qt 6.10.0, Qt VS Tools and Visual Leak Detector (see below).

You also need to install vcpkg on Windows and create an Lubuntu 22.04 build system (typically in a Virtual Machine). Instructions on setting up the Linux build system are in "Setup Linux.txt".

There are also instructions for setting up a macOS build system.

Qt 6.10.0,Qt VS Tools

Qt 6.10.0 is needed to build DeepSkyStacker 6.1.1 and the current development (master branch).

In addition to you you will also need to install the Visual Studio Extension Qt VS Tools : (Extensions/Manage Extensions).

You will need to use Extensions/Qt VS Tools/Qt Versions to set up the named Qt Installation called:

6.10.0_msvc2022_64

pointing to the relevant sub-directory of your Qt installations (for example C:\Qt\6.10.0\msvc2022_64).

Visual Leak Detector

You should install the version of VLD that is maintained by Alex Vanden Abeele as that now appears to be the only one that is being kept up to date. The version what was maintained by the Microsoft Azure team hasn't been updated for a long time. You can download version 2.5.12 of this from Visual Leak Detector. You should install it to C:\Program Files (x86)\Visual Leak Detector as that is the location that the DeepSkyStacker projects expect to find it. In the Visual Leak Detector installation wizard, be sure to select Visual Studio integration.
