\b readme Last month I wrote a version of the Unix(tm) utility MAKE. It runs under VAX/VMS and MSDOS 2.0. I am placing it in the public domain, and it is yours for the asking. You may copy it, or give it away. You can make any changes you like to it. All I ask is that you DO NOT TRY TO SELL IT. Anyway, there is now a MAKE for MSDOS. It is free, and it works pretty well. I'm giving it away because it might do the world some good. Who knows? Caveat: this version of MAKE is NOT compatible with the Unix(tm) version. Some differences are explained in the documentation. Most of the problem stems from the fact that I've never had a chance to use the original version of MAKE, and the documentation I've seen on it has been poor. My idea of what a make program should do is almost certainly different from what you Unix(tm) hackers are used to. Well, hell -- the software is worth what you paid for it. Have fun. In order to get MAKE running on your system, you need to: 1. Read the documentation file MAKE.MAN. (Yes, read the directions.) 2. Edit the file MAKE.H to represent your system (VAX/VMS or MSDOS 2.0.) 3. Recompile the source code by following the script file CMAKE.COM (for VAX/VMS) or CMAKE.BAT (for MSDOS 2.0.) VAX/VMS requires the DEC C compiler; MSDOS 2.0 requires Lattice C (or another C compiler of comparable quality) and the Macro Assembler. 4. Test out MAKE by running it on itself. (Make a backup first!) Good luck, Landon Dyer (G.DYER @ SU-SCORE) \e readme \b make.man MAKE(I) 3/10/84 MAKE(I) NAME MAKE - maintain multiple source files (VAX/VMS and MSDOS 2.0) SYNOPSIS MAKE [-N] [-A] [-F makefile] [name ...] DESCRIPTION MAKE is a utility inspired by the Unix(tm) command of the same name. MAKE helps maintain programs that are constructed from many files. MAKE processes a "makefile", a file which describes how to build a program from its source files, and produces a script file containing the commands necessary to recompile the program. Be careful: this MAKE is NOT compatible with Unix(tm) MAKE! The 'N' option causes MAKE to print out the steps it would follow in order to rebuild the program. The 'A' option tells MAKE to assume that all files are obsolete, and that everything should be recompiled. The 'F' option, followed by a filename, can be used to specify a makefile other than the default one. If no names are specified in the commandline, the first dependency in the makefile is examined. Otherwise, the specified root names are brought up to date. The default makefiles are: for VAX/VMS: MAKEFILE [-]MAKEFILE SYS$LOGIN:MAKEFILE for MSDOS: MAKEFILE ..\MAKEFILE If the first makefile cannot be found, MAKE attempts to use the next one. If no makefile is ever found, MAKE prints a diagnostic and aborts. THE MAKEFILE Comments begin with '!' and extend to the end of the line. A '!' (or almost any other character) may be escaped with the escape character (backslash (\) on VMS, backquote (`) on MSDOS). An escape character may be typed by doubling it (\\ or ``). The standard Unix escape codes are recognized (\n, \r, \t, \b, \f, `n, `r, `t, `b and `f). A makefile is a list of dependencies. A dependency consists of a root name, a colon, and zero or more names of dependent files. (The colon MUST be preceeded by whitespace.) For instance, in: make.exe : make.obj parsedir.obj file.obj macro.obj mk.h the file 'make.exe' depends on five other files. A root name with an empty dependency, as in: print : is assumed NEVER up to date, and will always be recompiled. The dependency list may be continued on successive lines: bigfile.exe : one.obj two.obj three.obj four.obj five.obj six.obj gronk.obj freeple.obj scuzzy.lnk frog.txt greeble.out Any number of 'method' lines may follow a dependency. Method lines begin with an ascii tab. When a file is to be recompiled, MAKE copies these method lines (minus the tab) to the script file. For example, in: make.exe : make.obj parsedir.obj file.obj macro.obj mk.h $link make, parsedir, file, macro $write sys$output "Just another version of MAKE ..." $purge the three lines following the dependency make up the method for recompiling (or in this case, re-linking) the file 'make.exe'. If the macro "~INIT" is defined, its text will appear first in the script file. If the macro "~DEINIT" is defined, its text will appear last in the script file. By defining these two macros, it is possible to configure the shell enviroment: ~INIT = $set term/nowrap\n$on error then goto err_handler ~DEINIT = $set term/wrap\n$exit\$err_handler:\n ~DEINIT = #(~DEINIT)$type err.log\n$exit will expand (in the script file) to: $set term/nowrap $on error then goto err_handler . . $set term/wrap $exit $err_handler: $type err.log $exit When a root's method is defined, the value of the macro "~BEFORE" is prefixed to the method, and the value of the macro "~AFTER" is appended to it. Frequently one wants to maintain more than one program with a single makefile. In this case, a "master dependency" can appear first in the file: allOfMyToolsAndHorribleHacks : cat peek poke.exe grunge cat : cat.exe cat.exe : .... (stuff for CAT.EXE) peek : peek.exe peek.exe : (stuff for PEEK.EXE) poke.exe : (stuff for POKE.EXE) grunge : grunge.com grunge.com : (stuff for grung) In other words, make will bring everything up to date that is somehow connected to the first dependency (its assumed that the incredibly lengthy filename specified in this example won't actually exist). MACROS A macro is defined by a line of the form (the '=' MUST be surrounded by whitespace): = A macro may be deleted by assigning an empty value to it. Macros may be redefined, but old definitions stay around. If a macro is redefined, and the redefinition is later deleted, the first definition will take effect: MAC = first ! MAC = "first" MAC = second ! MAC = "second" MAC = #(MAC) third ! MAC = "second third" MAC = ! MAC = "second" MAC = ! MAC = "first" MAC = ! MAC has no definition A macro may be referenced in two ways: # or #(macro-name) The first way only works if the macro's name is a single character. If the macro's name is longer than one character, it must be enclosed in parenthesis. ['#' may be escaped by doubling it ("##".)] For example, in: G = mk.h mk1.h OBJS = make.obj file.obj parsedir.obj macro.obj BOTH = #(OBJS) #G make.exe : #(OBJS) #G make.exe : #(BOTH) make.exe : mk.h mk1.h make.obj file.obj parsedir.obj macro.obj $write sys$output "This is a number sign --> ##" after macro expansion, the three dependencies will appear identical and the two '#'s in the last line will turn into one '#'. UNIX(tm) MAKE AND THIS ONE They are NOT the same. Do not expect Unix makefiles to work with this MAKE, even if you change the pathnames. There are some major differences between this version and the standard Unix(tm) MAKE: 1. The Unix(tm) comment character is '#', VAX/VMS's is '!'. 2. The Unix(tm) macro-expansion character is '$'. While this would have been easy to leave the same, the '$' character is used so often in VAX/VMS command-lines that I thought it best to change it to '#'. 3. Multiple root names are not allowed. Unix(tm) MAKE accepts lines of the form: name1 name2 : depend1 depend2 but this one doesn't. 4. There is no equivalent of double-colon ("::".) 5. There is no equivalent of .SUFFIXES, or the corresponding special macros. SAMPLE MAKEFILE ! ! VAX/VMS MAKE ! Landon Dyer !
