I seem to be getting build errors with the latest HiveOS release.

Initially I was getting errors for the libc++ library and GLIBCXX_3.4.26 wasn't found in the core s0.6:

./TBMiner: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by ./TBMiner)

so I upgraded the GCC compiler libraries to include .26:

apt-get upgrade libstdc++6
apt install gcc-9


but now I'm getting a OpenCL build error:

terminate called after throwing an instance of 'cl::BuildError'
  what():  clBuildProgram

So, now I'm stumped because I've updated the gcc compiler, the libraries and this is an internal build process, so I have no information about where it might be failing.  
Any help would be appreciated.

sudo apt-get install --only-upgrade libstdc++6
