Problem reloading KStars.

[Dan]

I'm trying to clear a problem and not getting success.  I have gone here 
and followed the directions: https://github.com/KDE/kstars

Problems begin here:

  96%] Building CXX object

                   ^~~~~~~~

The problem continues repeatedly, until finally:

'Tests/kstars_ui/CMakeFiles/test_ekos_meridianflip_specials.dir/all' failed

Can someone please help me out, I am not a programmer.

Best wishes,
