[comp.unix.ultrix] Making gnu emacs 18.55 shared on a PMAX

art@dinorah.wustl.edu (Arthur B. Smith) (10/19/89)

Hello, netlanders.  

	We have lots of emacs'ers here, so it is better for us to have 
emacs as a shareable executable (NMAGIC) rather than a demand paged
executable (ZMAGIC) file.  This works just dandy by adding the -n flag
to the link step in the ymakefile in gnu emacs 18.55 under Ultrix 3.1 on
a microvax, but it really does in a DECstation 3100 (same gnu, same 
Ultrix).  The unexec step (unexmips.c on the DS3100) wipes out because
the in-core magic number is wrong (it is, in fact zero).  

	Has anyone else out there run into this?  Did you overcome this
obstacle, or are you learning to live with lots of demand paging?  Dare
I tell unexmips.c that a zero there is ok, and it should just go on?
I'm quickly getting in over my head here!!!
