Hi Marcus,
Thanks (and to Michael) for the very quick follow-up! It is one
of the oldest distros around. I have been using it since the late 90s.

This does make sense. I have been upgrading it rather than
reformatting/reinstalling for many years. That said, this holiday I combed
through /usr/local/{include,lib} where a number of files from old versions
of manually installed packages resided, and removed those which clashed
with those from current packages which generally install under
/usr/{include,lib}. I did this having had similar problems in the past,
particularly with builds such as qt5.

Now you have given me some pointers I will check again and report back.

If I can't get anywhere on my current system I'll install a clean current
copy of Slackware elsewhere and trying building there.

Many thanks
Tom.
