Digging around online, I suspect that you may not have the GNU C++ compiler installed at all. Take this with a shaker of salt.

Subject: Linux failure

Hi devs
I've got my Linux box upgraded to a recent version of Ubuntu, so I'm no longer stuck on gcc version.
But I can't build either.  Something strange with /lib/cpp fails sanity check.  The log is below.
Can anyone help? I'm a bit stalled.
This call to "make" follows the same failure when I typed "sh validate -fast".   But by carrying on from where it got stuck the log is way shorter.
Thanks
Simon
