8e9464f1 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
735aabf6 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.

d1be9408 9# DGUX is an SVR4 derivative. It ships with gcc as the standard
735aabf6 10# compiler. Since version 3.0 it has shipped with Perl 4.036
c07a80fd 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.

c07a80fd 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
98# environment.

100# Starting with version 4.10 (the first time the OS supported Intel

103# The default $TARGET_BINARY_INTERFACE changed with version 4.10. The

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