Host OS is SuSE8.2 with linux22 compiled under 2.95.3 and l4 + the rest under 3.2 (i.e. reverted), all compiles terminated OK, all libraries & dependencies found to the best of my ability. The same error has stopped me for some 24 hours; I have been round the houses tidying up all I can find here so I await your advice with eagerness. In the meantime, to get a bit nearer, I have the Debian system ready for a similar assault when I have my energy restored... TIA David Denny
