3 # This is a hints file for DGUX, which is EMC's Data General's Unix. It
4 # was originally developed with version 5.4.3.10 of the OS, and then was
5 # later updated running under version 4.11.2 (running on m88k hardware).
6 # The gross features should work with versions going back to 2.nil but
7 # some tweaking will probably be necessary.
9 # DGUX is a SVR4 derivative. It ships with gcc as the standard
10 # compiler. Since version 3.0 it has shipped with Perl 4.036
11 # installed in /usr/bin, which is kind of neat. Be careful when you
12 # install that you don't overwrite the system version, though (by
13 # answering yes to the question about installing perl as /usr/bin/perl),
14 # as it would suck to try to get support if the vendor learned that you
15 # were physically replacing the system binaries.

19 # The standard system compiler is gcc, but invoking it as cc changes its
20 # behavior. I have to pick one name or the other so I can get the
21 # dynamic loading switches right (they vary depending on this). I'm
22 # picking gcc because there's no way to get at the optimization options
23 # and so on when you call it cc.

90 # DG has this thing set up with symlinks which point to different places
91 # depending on environment variables (see elink(5)) and the compiler and
92 # related tools use them to access different development environments
93 # (COFF, ELF, m88k BCS and so on), see sde(5). The upshot, however, is
94 # that when a normal program tries to access one of these elinks it sees
95 # no such file (like stat()ting a mis-directed symlink). Setting
96 # $plibpth to explicitly include the place to which the elinks point
97 # allows Configure to find libraries which vary based on the development
100 # Starting with version 4.10 (the first time the OS supported Intel
101 # hardware) all libraries are accessed with this mechanism.
103 # The default $TARGET_BINARY_INTERFACE changed with version 4.10. The
104 # system now comes with a link named /usr/sde/default which points to
105 # the proper entry, but older versions lacked this and used m88kdgux

123 NOTE: I can't figure out what SDE is used by default on this machine (I
124 didn't find a likely directory under $sde_path). This is bad news. If
125 this is a R4.10 or newer system I'm not going to be able to find any of
126 your libraries, if this system is R3.10 or older I won't be able to find
127 the math library. You should re-run Configure with the environment
128 variable TARGET_BINARY_INTERFACE set to the proper value for this
129 machine, see sde(5) and the notes in hints/dgux.sh.
