[Discuss-gnuradio] Fwd: Re: Sigh - 16.04 build failure

[Mike]

Found it ! I discovered a duplicate set of headers in /usr/local/include 
and /usr/include, fixing this didn't fix the problem.

After several hours wondering what was wrong with the headers I found 
there were two versions of libcppunit. This must have been a leftover of 
the upgrade to 16.04 as it should surely have been deleted when replaced 
by the updated version.

The older libcppunit-1.12 in /usr/lib/ and the newer, libcppunit-1.13 
was in /usr/lib/x86_64-linux-gnu/ - why in different directory I have no 
idea.

So the right headers were there but the wrong library was being selected 
which is why it failed to build.

I deleted the older version and build progressed.

So what else has the version upgrade left lurking?
