These would be the RHEL 4.x compatibility packages. They might do what you need though, by giving you an even older build chain then is normal for either FC3 or FC6. Generally, code built with an older build chain, so long as it it not too old, will result in executables that will run on a various newer systems. I don't know if you will also need compat-lib??? libraries installed on your systems as well, I would guess at least a compat-libstdc++3.4.6-<mumble> and a compat-libgcc-3.4.6-<mumble> would also be needed (with the -devel's on your build box) -- my CentOS 4.4 system has libgcc-3.4.6-3/libgcc-devel-3.4.6-3, and libstdc++-3.4.6-3/libstdc++-devel-3.4.6-3 installed, along with gcc-3.4.6-3 and gcc-c++-3.4.6-3. > > -- Robert Heller -- 978-544-6933 Deepwoods Software -- Linux Installation and Administration http://www.deepsoft.com/ -- Web Hosting, with CGI and Database [EMAIL PROTECTED] -- Contract Programming: C/C++, Tcl/Tk _______________________________________________ help-gplusplus mailing list help-gplusplus@gnu.org http://lists.gnu.org/mailman/listinfo/help-gplusplus
