This is an attempt at keeping a log of what needs to be done to build KStars from source on Windows using the emerge tool.

Initial steps

This article: is great for almost all things.

If you are using Windows 10, please see the notes at the very bottom of the page

Also, do not try to use Cygwin to get python and git. The entire process does not want you to have the standard GNU tools in path etc. Instead, get them from the standard installers at and

When installing git using the installer from, make sure you choose the option where git is accessible from command line, but the MinGW tools are not added to the path (Second option out of the three as of this writing). Adding the MinGW32 tools to the path ends up causing trouble while building with the MinGW compiler.

Please note that emerge has a verbose mode (emerge --verbose) which is very helpful for diagnosing any problems.

Building Qt packages

First build Qt Base by emerging it

emerge qtbase

For some strange reason, emerge may get stuck half way in powershell. It looks like hitting enter periodically ensures that the process goes on (why????). Of course this could just be coincidence but it seems unlikely. (This could be due to a virtualbox feature -- the author of this blurb is running the Windows OS in virtualbox)
