Hej Mike and Simon,
allright – although I successfully (conventionally) installed a more recent gcc on my centOS 7 I ran into further trouble with the actual Qt5.15 compilation. Now I brought all back to centOS defaults including gcc4.8 and Qt5.9.
As suggested by you I will now give it a try with the Developer Toolset and get back later.
Thanks and best
Alex
