	Ok, I probably only thought about including the writeup in the
	documentation.   I know I did write up a moderately lengthy 
	article about dealing with the overlay setup in response to a
	problem someone was having.  I just never went and incorporated it 
	into the setup/installatino documentation ;(

	One thing, obvious now that I think of it, I forgot to mention last
	night is that "too big for type 431" can also happen if the D space
	total is too large.   If 'MAXUSERS' is set too high for example
	then more than 48KB of D space will be needed and the linker will
	complain.    Look at the sum of the DATA and BSS segments (it might
	be necessary to sum up the .o files individually) - if it's pushing
	48KB then that's the problem.

	Cheers,

[pups] 2.11BSD "make unix" aborts Error 141

[Jonathan Engdahl]

I'm running essentially the CURLY 2.11BSD system with networking on a
PDP-11/53. When I go to rebuild unix with "make all", the build will run for
a while, then quit with "Error 141". If I type "make all" again, it keeps on
going for a while. After several iterations of this, eventually the make
completes, and the system will boot the result. What is this "Error 141"
business?

I've not looked for the cause of this yet. I'm being lazy, and hoping
someone has seen this before and can give me a quick answer, before I go
digging.

  I don't recall seeing any overlay info when I set up my 11/73 back in
January.  I even asked the dreaded overlay FAQ here!  :)  I was also at
431.

	Do you have any 0 length overlays?   There can't be any gaps in the
	overlay structure.

	For example, this is legal:

		overlays: 8128,7552,8000,7296,8192,7424,5824,6784,3520

	but this is not:
		
		overlays: 8128,7552,8000,7296,8192,0,5824,6784,3520

	You might need to go thru the Makefile too.  Good idea to eliminate
	drivers you don't have (save their D-space requirements) but that
	can create empty overlays and that does not work.

	Hmmm, patch level 431 is recent enough I'd have thought to avoid
	a 'ld' problem (current is 444 but nothing recently has touched
	ld).

	What is the output from 'size unix.o'?

Steven,

I'm building a 2.11BSD kernel on my 11/73 (so I can include the networking
code and put my machine on the LAN!), and I'm seeing the error "too big for
type 431".  Through the wonders of Google, I saw your discussion of this
error and followed your advice (from 1996!).  However, when I ask 'size
unix.o', I get a size comfortably within the limits for base - 50112, well
below the 57344 you cite.  None of the overlays exceeds 8192, and the 'total
text' figure is well below your example, too.  FWIW, I did a 'naive build'
first, copying GENERIC and changing a few parameters; after seeing the error
'text segment too big' I went through the config file with a little more
thought and eliminated drivers I clearly didn't need (I don't have RL01/02s,
for instance).  Then I started getting this error.  I did a 'make clean'
just to be sure, but still make gives me the 'too big for type 431' error.
(Yes, I RTFM on ld.)

I am standing here beside myself.  :-)  And I am humbly soliciting
suggestions....  -- Ian

PS: I'm at patch level 431, per the VERSION file.
