Hi boosters I just tried to build boost 1.34.1 from source on my laptop running Linux Ubuntu 8.04 and gcc version 4.2.3.

So my pb comes from the brand new bjam executable (tools/jam/src/bin.linuxx86/bjam) that segfaults systematically for some mystery reason. Using bjam from the 'bjam' Debian package is ok so I can of course use the '--with-bjam=/usr/bin/bjam' switch to build the whole boost stuff. But I'm not satisfied with this solution for the standard boost build procedure worked perfectly as expected for boost 1.34.1 under my previous Ubuntu 7.04/gcc 4.1 and also for the new boost 1.36.0/gcc 4.2.3. Maybe someone could give me some hints to understand this problem? thanks a lot regards frc -- Francois Mauger Laboratoire de Physique Corpusculaire de Caen et Universite de Caen
