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 RS |
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. | |

127 | the math library. You should re-run Configure with the environment | |
