# 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.
|
|
#
|
|
# Be aware that if you opt to use dynamic loading you'll need to set
|
|
# your $LD_LIBRARY_PATH to include the source directory when you build,
|
|
# test and install the software.

# 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.

# The 4.036 and 5.001 hints files both contained these. The 5.001 hints

# One last note: The 5.001 hints file said "you don't want to use

# 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

# 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. The

NOTE: I can't figure out what SDE is used by default on this machine (I

didn't find a likely directory under $sde_path). This is bad news. If

this is a R4.10 or newer system I'm not going to be able to find any of
|
|
your libraries, if this system is R3.10 or older I won't be able to find
|
|
the math library. You should re-run Configure with the environment
|
|
variable TARGET_BINARY_INTERFACE set to the proper value for this

machine, see sde(5) and the notes in hints/dgux.sh.
