# $Id: dgux.sh,v 1.9 2001-05-07 00:06:00-05 Takis Exp $ # This is a hints file for DGUX, which is EMC's Data General's Unix. It # was originally developed with version 5.4.3.10 of the OS, and then was # later updated running under version 4.11.2 (running on m88k hardware). # The gross features should work with versions going back to 2.nil but # some tweaking will probably be necessary. # # DGUX is an SVR4 derivative. It ships with gcc as the standard # compiler. Since version 3.0 it has shipped with Perl 4.036 # installed in /usr/bin, which is kind of neat. Be careful when you # install that you don't overwrite the system version, though (by # answering yes to the question about installing perl as /usr/bin/perl), # as it would suck to try to get support if the vendor learned that you # were physically replacing the system binaries. # # -Roderick Schertler # The standard system compiler is gcc, but invoking it as cc changes its # behavior. I have to pick one name or the other so I can get the # dynamic loading switches right (they vary depending on this). I'm # picking gcc because there's no way to get at the optimization options # and so on when you call it cc. ########################################## # Modified by Takis Psarogiannakopoulos # Universirty of Cambridge # Centre for Mathematical Sciences # Department of Pure Mathematics # Wilberforce road # Cambridge CB3 0WB , UK # e-mail # Use GCC-2.95.2/3 rev (DG/UX) for threads # This compiler supports the -pthread switch # to link correctly DG/UX 's -lthread. # March 2002 ########################################### cc=gcc ccflags="-DDGUX -D_DGUX_SOURCE" # Debug build.
