Problem building kstars on Enterprise Linux 7

[Rhys Morris]

Hi kstars devels,

I wand to try out Ekos, so I'm trying to build kstars 2.9.7 from source on Scientific Linux 7 (which is almost identical to Centos7 and RedHat Enterprise Linux7). I have installed a load of dependencies and built the most recent libindi. Cmake (or in my case cmake3 )runs fine, but make fails as below. I can provide more lines if required.

Any suggestions how to get past this would be gratefully received.
Regards,
Rhys
