| This is the VMS port of GNU Make version 3.75. |
| |
| It is based on the VMS port of GNU Make 3.60 by Mike Moretti. |
| |
| This port was done by Klaus Kรคmpf (kkaempf@progis.de) of |
| proGIS Software, Aachen, Germany |
| |
| To build Make, simply type @makefile. This should compile all the |
| necessary files and link Make. |
| There is also a file called makefile.vms. If you already have GNU |
| Make 3.74 built you can just use Make with this makefile to rebuild. |
| |
| Here are some notes about GNU Make for VMS: |
| |
| Libraries are not supported. They were in GNU Make 3.60 but somehow I didn't |
| care porting the code. If there is enough interest, I'll do it at some |
| later time. |
| |
| 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] |
| |
| None of the stuff in vpath.c has been implemented yet. |
| |
| 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. |
