Build failure - error: bits/c++config.h: No such file or directory

[Robert Jones]

I've built various versions of Gcc many times on different machines, with
no problems. I have a script to record my learnings, so I'm pretty sure
I'm doing what I always do, but this time round I've hit a problem.

This happens building Gcc 8.2 and 6.4, so it's not anything specific to
latest
version(s)

My native C++ compiler reports

g++ (GCC) 4.4.7 20120313 (Red Hat 4.4.7-23.0.1)

Operating system is

Linux [...] 4.1.12-124.19.7.el6uek.x86_64 #2 SMP Sat Sep 29 17:30:15 PDT
2018 x86_64 x86_64 x86_64 GNU/Linux

And the machine is a VM.

My first error are

error: bits/c++config.h: No such file or directory
error: ‘_GLIBCXX_END_NAMESPACE’ does not name a type

Any idea how to fix these?

Kind Regards

Rob.
