Error When Making Local Copy of ROOT

_ROOT Version: 6.20.02
_Platform: Linux
_Compiler: GCC verison 9

Hello! When trying to make/compile a local copy of ROOT, I get a very odd-looking and rather long error with which I am not familiar at about 97% of the way through gmake:

`[ 97%] Generating tutorials/hsimple.root

I am trying to compile and install a local copy using gcc-9.1.0 so that it will work with the KATRIN software KASSIOPEIA, and I will admit that this error has me stumped. I have found similar posts to this, however it looks like they appear with ROOT after it has been installed, whereas here it is prohibiting me from completing the installation.

Thank you so much!

is the crux of the problem (mismatch between build and run-time environment).

Ah, that was the problem! It works now, thank you so much!
