Its really great to have an 'mkdep' with Umax 4.3 To test it, I 'cd'ed to a source directory and entered 'make depend' Sure enough, it compiled all of my source code, and removed all of the dependencies from Makefile. We really shouldn't need to do it this way, but here's a 'mkdep' that seems to work: (I used to use this with Umax 4.2). #! /bin/sh # This is a shell archive. Remove anything before this line, then unpack # it by saving it into a file and typing "sh file". To overwrite existing # files, type "sh file -c". You can also feed this as standard input via # unshar, or by typing "sh <file", e.g.. If this archive is complete, you # will see the following message at the end: # "End of shell archive." # Contents: mkdep # Wrapped by rickert@mp.cs.niu.edu on Fri Jun 8 16:30:18 1990 PATH=/bin:/usr/bin:/usr/ucb ; export PATH if test -f 'mkdep' -a "${1}" != "-c" ; then echo shar: Will not clobber existing file \"'mkdep'\" else echo shar: Extracting \"'mkdep'\" \(2902 characters\) sed "s/^X//" >'mkdep' <<'END_OF_FILE' X#!/bin/sh - X# X# Copyright (c) 1988 The Regents of the University of California.

Here's a "mkdep" that uses "apply" to run the dependencies in parallel. Under UMAX4.2, you must have a copy of the 4.3BSD "cpp" around to get "cpp -M"; under UMAX4.3 you can just use "cc -M". Actually, under UMAX4.3, you should *really* not "make depend" at all, but "cc -MD". This is a clever hack which compiles the file *and* builds dependencies (into .d files). You then add the following line to the end of the link-command: cat *.d > .depends Unfortuneately, UMAX4.3 "make" has not picked up the post-tahoe feature of automatically reading a ".depends" file for dependencies. You have to explicitly use: make -f Makefile -f .depends The advantage to "-MD" is that you don't have to do two passes, and on a huge source tree (like for the Annex) this is a big win.
