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. + |
