It is based on the VMS port of GNU Make 3.60 by Mike Moretti.

This port was done by Klaus K<>mpf <kkaempf@progis.de> of

To build Make, simply type @makefile. This should compile all the
|
1997-08-27 20:30:54 +00:00
|
|
|
|
necessary files and link Make. There is also a file called
|
|
|
|
|
|
makefile.vms. If you already have GNU Make built you can just use
|
|
|
|
|
|
Make with this makefile to rebuild.

Here are some notes about GNU Make for VMS:
|
|
|
|
|
|
|
|
|
|
|
|
The variable $^ separates files with commas instead of spaces (It's the
|
|
|
|
|
|
natural thing to do for VMS).
|
|
|
|
|
|
|
|
|
|
|
|
See defaults.c for VMS default suffixes and my definitions for default
|
|
|
|
|
|
rules and variables.
|
|
|
|
|
|
|
|
|
|
|
|
The shell function is not implemented yet.
|
|
|
|
|
|
|
|
|
|
|
|
Load average routines haven't been implemented for VMS yet.
|
|
|
|
|
|
|
|
|
|
|
|
The default include directory for including other makefiles is
|
|
|
|
|
|
SYS$SYSROOT:[SYSLIB] (I don't remember why I didn't just use
|
|
|
|
|
|
SYS$LIBRARY: instead; maybe it wouldn't work that way).
|
|
|
|
|
|
|
|
|
|
|
|
The default makefiles make looks for are: makefile.vms, gnumakefile, makefile.,
|
|
|
|
|
|
and gnumakefile. .
|
|
|
|
|
|
|
|
|
|
|
|
The stat() function and handling of time stamps in VMS is broken, so I
|
|
|
|
|
|
replaced it with a hack in vmsfunctions.c. I will provide a full rewrite
|
|
|
|
|
|
somewhere in the future. Be warned, the time resolution inside make is
|
|
|
|
|
|
less than what vms provides. This might be a problem on the faster Alphas.
|
|
|
|
|
|
|
|
|
|
|
|
You can use a : in a filename only if you preceed it with a backslash ('\').
|
|
|
|
|
|
E.g.- hobbes\:[bogas.files]
|
|
|
|
|
|
|
|
|
|
|
|
Make ignores success, informational, or warning errors (-S-, -I-, or -W-).
|
|
|
|
|
|
But it will stop on -E- and -F- errors. (unless you do something to override
|
|
|
|
|
|
this in your makefile, or whatever).
|
|
|
|
|
|
|
|
|
|
|
|
Remote stuff isn't implemented yet.
|
|
|
|
|
|
|
|
|
|
|
|
Multiple line DCL commands, such as "if" statements, must be put inside
|
|
|
|
|
|
command files. You can run a command file by using \@.

VMS changes made for 3.74.3
|
|
|
|
|
|
|
|
|
|
|
|
Lots of default settings are adapted for VMS. See default.c.
|
|
|
|
|
|
|
|
|
|
|
|
Long command lines are now converted to command files.
|
|
|
|
|
|
|
|
|
|
|
|
Comma (',') as a separator is now allowed. See makefile.vms for an example.
