# $Id: dgux.sh,v 1.8 1996-11-29 18:16:43-05 roderick Exp $ # This is a hints file for DGUX, which is 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 a 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 # Here are the things from some old DGUX hints files which are different # from what's in here now. I don't know the exact reasons that most of # these settings were in the hints files, presumably they can be chalked # up to old Configure inadequacies and changes in the OS headers and the # like. These settings might make a good place to start looking if you # have problems. # # This was specified the the 4.036 hints file. That hints file didn't # say what version of the OS it was developed using. # # cppstdin='/lib/cpp' # # The 4.036 and 5.001 hints files both contained these. The 5.001 hints # file said it was developed with version 2.01 of DGUX. # # gidtype='gid_t' # groupstype='gid_t' # uidtype='uid_t' # d_index='define' # cc='gcc' # # These were peculiar to the 5.001 hints file. # # ccflags='-D_POSIX_SOURCE -D_DGUX_SOURCE' # # # an ugly hack, since the Configure test for "gcc -P -" hangs. # # can't just use 'cppstdin', since our DG has a broken cppstdin :-( # cppstdin=`cd ..; pwd`/cppstdin # cpprun=`cd ..; pwd`/cppstdin # # One last note: The 5.001 hints file said "you don't want to use # /usr/ucb/cc" in the place at which it set cc to gcc. That in # particular baffles me, as I used to have 2.01 loaded and my memory # is telling me that even then /usr/ucb was a symlink to /usr/bin. # 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. case $cc in '') cc=gcc case $optimize in '') optimize=-O2;; esac ;; esac usevfork=true # DG has this thing set up with symlinks which point to different places # depending on environment variables (see elink(5)) and the compiler and # related tools use them to access different development environments # (COFF, ELF, m88k BCS and so on), see sde(5). The upshot, however, is # that when a normal program tries to access one of these elinks it sees # no such file (like stat()ting a mis-directed symlink). Setting # $plibpth to explicitly include the place to which the elinks point # allows Configure to find libraries which vary based on the development # environment. # # Starting with version 4.10 (the first time the OS supported Intel # hardware) all libraries are accessed with this mechanism. # # The default $TARGET_BINARY_INTERFACE changed with version 4.10.
