IIRC, you could use longer names than that (in C), but external references
only used the first 7 (in C - C symbols had a leading '_' tacked on; I used to
know why), 8 (in assembler).

Seems unlikely - see below.

Someone who actually looked at the source:

  https://www.tuhs.org/cgi-bin/utree.pl?file=V7/usr/src/cmd/ld.c

instead of just guessing. Give that man a star!

I spent a while looking at the code, trying to figure out i) how it works, and
ii) what's going wrong with that message, but I don't have a definitive
answer. The code is not super well commented, so one has to actually
understand what it's doing! :-)

It seems to my initial perusal that it maintains two symbol tables, one for
globals (which accumulates as each file is processed), and one for locals
(which is discarded/reset for each file). As Werner mentioned, the message
appears when a local symbol referenced in the relocation information in the
current file can't be found (in the local symbol table).

It's not, I think, simply due to too many local symbols in an input file -
there seems to be a check for that as it's reading the input file symbol
table:

   if (lp >= &local[NSYMPR])
           error(1, "Local symbol overflow");
   *lp++ = symno;
   *lp++ = sp;

although of course there could be a bug which breaks this check. It seems to
me that this is an 'impossible' error, one which can only happen due to i) a
bug in the loader (a fencepost error, or something), or ii) an error in the
input a.out file.

I don't want to spend more time on it, since I'm not sure if you've managed to
bypass the problem. If not, let me know, and we'll track it down. (This may
involve you addding some printf's so we have more info about the details.)

Precisely to avoid collisions between external names in C and names in
assembler (whose namespace was flat except for local labels) when they were
linked into your program.

For similar reasons, F77 names had a trailing '_' tacked on.

I've spent some time in ld.c lately:
https://github.com/bsdimp/mk211bsd/blob/master/hints/160.ld.diff
since I had to retro-fit the new archive support into the 2.10.1BSD +
patches posted to comp.bugs.2bsd version of ld I needed for 2.11BSDpl0 :)
Ideally, nobody would be able to tell my retrofits from the usenet patch
that's also in this diff...

Thanks.  Since I am already pre-preprocessing the macros that generate the
FORTH builtin words (no token pasting in K&R C), I can trivially split them
out into individual files each with a single short function.

It's likely too many. Ld used to have lots of fixed sized arrays... I had
to hack on the 2.10.1BSD to change supported ar formats and noticed. Also
had to tweak some of the constants to get something much bigger compiling.
The BSD ld had overlay suppot merged into it, but was otherwise quite
similar to V7, though I've not done a deep dive into ld from v7...

Tl;dr: chances are good more, smaller files will work.

So maybe I missed a symbol when I was trying to make everything unique in 8
chars?  There are no external symbols; all that's in my forth.h are macros
and typedefs.

Here's the output of "size," which doesn't tell me much....I think.  Unless
in v7 data has to be under 32K rather than 64K?  Surely not, right?  (The
data segment is 32K of main memory for FORTH, plus some for the startup
Forth script, plus a bit for the line buffer and some miscellaneous pointer
variables.)

$ size forth.o
7580+34034+0 = 41614b = 0121216b

I think we also sometimes forget how small 64K was.  Terseness wasn't

That's funny, I was just talking to my older son yesterday.  We had the
chat about how much you could get done in a semester in college, a buddy
and I did about 80% of an Ada compiler.  It was a lot.  I told my kid 
that industry is different, it moves way slower and that is because
there is a huge difference between something you get done in a few months
and throw away and something that you are going to hand off to users.
Error handling and messages matter a lot.  Backwards compatibility 
matters a lot.

Isn't Adam working on v7?  If so, not so great error messages are
sort of understood, it was early times.  They got better.

K&R 1st edition Reference Manual section 2.2 mentions 8 (including
underscore) as the number of significant characters, though names can
be longer. External names are more restricted: it has a table of
limits for external names for various targerts. PDP-11 is 7 chars,
Honeywell 6000 is 6 chars (with no case distinction).

Thanks.

Part of getting the thing to compile for V7 was shortening the names so they were unique in the first 8 characters (rather like I had to do for Frotz on TOPS-20).  

I suspect “too many symbols” since I wrote a cpppp (C preprocssor preprocessor) to emulate the symbol pasting in the original code, and there are a _LOT_ (well, 71) of BUILTIN(a,b,c,d) and ADD_BUILTIN(c) which each expand into a function.

Wondering if breaking it up into multiple source files, and thus object files, would help.  Doubt it will but maybe I will try that tomorrow.

Try cc -c and do size on the .o. that might give you a hint about what is

8 I think was the limit.

Could that cause this error?

Maybe too many symbols?

The error comes from lookloc. This is called for external type relocations.
It searches the local symbol table for something that matches the
relocation entry. This error happens when it can't find it...

Not sure of the root causes for *that* though.

Looking through the code, I see some awfully long function names.   Does anyone recall if there are/were limits on the size of variable and function names?

Could that cause this error?

I finally munged lbforth.c (https://gist.github.com/lbruder/10007431) into
compiling cleanly on mostly-stock v7 with the system compiler (lbforth
itself does fine on 211BSD, but it needs a little help to build in a real
K&R environment).

Which would be nice, except that when it gets to the linker....

$ cc -o 4th forth.c
ld:forth.o: Local symbol botch

WTF?

How do I begin to debug this?
