Guys,

You're off on the wrong tack. Those are cmake tests to determine if certain functions are present and it's expected for some of them to fail. They cause preprocessor variables to be set or not and there are checks in the code that adjust what functions are called depending on those preprocessor variables.

There's seldom any need to look at CMakeOutput.txt or CMakeError.txt, and you need a good understanding of how build systems work first in order to interpret them. Just look at what cmake writes to the terminal, that almost always tells you what's wrong in simple terms.

John, 

Sorry, I deleted this before responding and had to grab a copy from the
archives.

My wife says I can't see anything right in front of my face!!  That must
be true in this case.  I started from the point of building a minimal
Disco schroot environment.  Knowing that GnC compiles in my environment
under the full Disco set of packages but fails with the below snippet
from the end of the string of messages, I made the presumption that the
failure was due to a package missing in the minimal environment. 

Hopefully, if we can figure this out for Disco under schroot, then we
can do Bionic in a similar environment.

So, given the below, what am I not seeing that I should see (and thus
fix)!  Or, have I not gone back far enough to catch the critical
message?  My initial thought is that something to do with pthreads isn't
loaded in the minimal environment.
