I have now added a third version generated under Redhat5 with egcs. g++ and egcs seems to be incompatible regarding some low level libraries. This looks like a mess. The 3 versions now available from our Web site are: - Redhat 4.2 with gcc 2.7 - Redhat 5.0 with gcc 2.7 - Redhat 5.0 with egcs 2.90.27 the third version has been generated on my laptop with: (pcnotebrun.cern.ch) [984] g++ -v Reading specs from /usr/lib/gcc-lib/i586-unknown-linux/egcs-2.90.27/specs gcc version egcs-2.90.27 980315 (egcs-1.0.2 release) Rene Brun
