manheime@nbs-amrf.UUCP (Ken Manheimer) (05/13/86)
[I wrote this up yesterday, and discovered in the meantime that our
Eunice upgrade is on the way; i gather that this version of Eunice
will emulate bsd 4.2 fairly closely; if that is truly the case then
the issues below may be moot as far as i'm concerned. I'm posting
this anyway since other people may be sticking with the 4.1 bsd
version of Eunice may be able to benefit from my experiences (who
knows, if it's full of problems we may be also...), and in any case
my curiousity is generally not deterred by practical considerations.]
I just spent part of the weekend and part of [yesterday] attempting
to get Gnu Emacs (version 17.43) operational under Eunice (eunice
version 4.2, which is essentially bsd 4.1 (moreorless). I gather
there's a new version of eunice out or impending, but we haven't
received any notice of it...). I've made substantial progress, to
the point where i can start up temacs and actually insert
carriage-returns to my hearts content. Can't do anything else with
it though (particularly not load lisp). (More details about the
fixes i discovered up to this point and the problems i'm having can
be found below.)
I'm writing this in the hope that someone out there has either
surmounted my current problem and knows a quick fix, or even
better, has already accomplished the whole port and can clue me in.
At the bottom you'll find a ChangeLog, an s-eun4.1.h eunice-specific
header file, and diffs of the fixes i have implemented to this point.
Some of the changes are clear fixes, others are more tentative
guesses that worked.
In the meanwhile, here's what i can garner of the current problem.
As i mentioned, i can get temacs to start up and in, though it comes
up with the message:
'Bare impure Emacs (standard Lisp code not loaded)'
even when the '-l' load flag option is correctly specified (in which
case the 'function definition void' message mentioned below also
appears).
The only keys correctly processed are carriage-returns (as near as i
can test them, of course; the buffer-modification indicator on the
mode line is changed on the first <cr>, the cursor moves down line by
line, and half-screen scrolling happens just right when the end of
screen is reached). No other functions seem to be defined, though the
symbols for all the basic keys (as defined in cmds.c: keys_of_cmds)
are established - the error message:
'Symbol's function definition is void: <some-or-other-command>'
is evoked for all these keys except <cr>. (Both \C-X and \E prefixes
also elicit the error message. Only way to exit is to kill the
session from another process.)
I took a superficial look to see what distinguishes the newline
command from the other primitive ones, and the only thing i could find
was the fact that its key definition comes first in keys_of_cmds, so
of course it tried putting it later on. Made no difference at all.
When this GNU temacs is run in '-batch' mode you wind up in a weird
state where you can enter input, but inevitably get the 'function def
void' message for each character on any line that you enter. However,
<esc> gets you out cleanly, and ^C/^Y(Eunice/Dec correlate of ^Z) will
perform their respective interrupts, getting you out uncleanly. As i
mentioned earlier, the '-l' load the Makefile tries to do (for
producing a dumpable emacs) fails with one of the 'void function
definition' messages for 'load'.
The source changes are below my signature.

1. ChangeLog additions, src/ChangLog:
------------------------------------------------------------------------
Sat May 10 19:30 1986 Ken Manheimer (...!seismo!nbs-amrf!manheime)
* generated s-eun4.1.h
Eunice doesn't have gettimeofday, and even though it does have
<sys/time.h> have to #undef HAVE_TIMEVAL.
Eunice doesn't have links, lstat: '#undef S_IFLNK','#define lstat stat'
* malloc.c
Problems with assumption of use of getrlimit in all of BSD, had
to alter #ifdefs to take account of Eunice.
Not only doesn't Eunice have bstring routines, it also doesn't
have memcopy, memcmp, etc. Created our own versions of the
bstring routines.
* process.c
Made neglected #ifdef enclosures to references to stuff from
sys/time.h using #ifdef HAVE_TIMEVAL/#endif pairs.
* filelock.c
Had to provide alternate chmod for fchmod calls, which aren't
present in Eunice.
* ymakefile
Mustn't include -ljobs; they're inherent in -lc.
Added -noshare to load options, to circumvent redundancies between
-lc and (intrinsic) shared C libraries.
Also, changed some of the /usr/local/lib/... configuration
specs to /usr/local/src/... i'm taking the lazy approach to
configuration, especially due to the lack of file links in
eunice to make a configuration conducive to both recompilation
and sensible organization.
