GNU make NEWS -*-indented-text-*- History of user-visible changes. 18 Aug 1997 Copyright (C) 1992, 1993, 1994, 1995, 1996, 1997 Free Software Foundation, Inc. See the end for copying conditions. Please send GNU make bug reports to bug-gnu-utils@prep.ai.mit.edu. Version 3.76 * GNU make now uses automake to control Makefile.in generation. This should make it more consistent with the GNU standards. * VPATH functionality has been changed to incorporate the VPATH+ patch, previously maintained by Paul Smith . See the manual. * Make defines a new variable, `MAKECMDGOALS', to contain the goals that were specified on the command line, if any. Modifying this variable has no effect on the operation of make. * A new function, `$(wordlist S,E,TEXT)', is available: it returns a list of words from number S to number E (inclusive) of TEXT. * Instead of an error, detection of future modification times gives a warning and continues. The warning is repeated just before GNU make exits, so it is less likely to be lost. * Fix the $(basename) and $(suffix) functions so they only operate on the last filename, not the entire string: Command Old Result New Result ------- ---------- ---------- $(basename a.b) a a $(basename a.b/c) a a.b/c $(suffix a.b) b b $(suffix a.b/c) b/c * The $(strip) function now removes newlines as well as TABs and spaces. * The $(shell) function now changes CRLF (\r\n) pairs to a space as well as newlines (\n). * Updates to the Windows 95/NT port from Rob Tulloh (see README.W32). * Eli Zaretskii has updated the port to 32-bit protected mode on MSDOS and MS-Windows, building with the DJGPP v2 port of GNU C/C++ compiler and utilities. See README.DOS for details, and direct all questions concerning this port to Eli Zaretskii or DJ Delorie . * John W. Eaton has updated the VMS port to support libraries and VPATH. Version 3.75 * The directory messages printed by `-w' and implicitly in sub-makes, are now omitted if Make runs no commands and has no other messages to print. * Make now detects files that for whatever reason have modification times in the future and gives an error. Files with such impossible timestamps can result from unsynchronized clocks, or archived distributions containing bogus timestamps; they confuse Make's dependency engine thoroughly. * The new directive `sinclude' is now recognized as another name for `-include', for compatibility with some other Makes. * Aaron Digulla has contributed a port to AmigaDOS. See README.Amiga for details, and direct all Amiga-related questions to . * Rob Tulloh of Tivoli Systems has contributed a port to Windows NT or 95. See README.W32 for details, and direct all Windows-related questions to . Version 3.73 * Converted to use Autoconf version 2, so `configure' has some new options. See INSTALL for details. * You can now send a SIGUSR1 signal to Make to toggle printing of debugging output enabled by -d, at any time during the run. Version 3.72 * DJ Delorie has ported Make to MS-DOS using the GO32 extender. He is maintaining the DOS port, not the GNU Make maintainer; please direct bugs and questions for DOS to . MS-DOS binaries are available for FTP from ftp.simtel.net in /pub/simtelnet/gnu/djgpp/. * The `MAKEFLAGS' variable (in the environment or in a makefile) can now contain variable definitions itself; these are treated just like command-line variable definitions. Make will automatically insert any variable definitions from the environment value of `MAKEFLAGS' or from the command line, into the `MAKEFLAGS' value exported to children. The `MAKEOVERRIDES' variable previously included in the value of `$(MAKE)' for sub-makes is now included in `MAKEFLAGS' instead. As before, you can reset `MAKEOVERRIDES' in your makefile to avoid putting all the variables in the environment when its size is limited. * If `.DELETE_ON_ERROR' appears as a target, Make will delete the target of a rule if it has changed when its commands exit with a nonzero status, just as when the commands get a signal. * The automatic variable `$+' is new. It lists all the dependencies like `$^', but preserves duplicates listed in the makefile. This is useful for linking rules, where library files sometimes need to be listed twice in the link order. * You can now specify the `.IGNORE' and `.SILENT' special targets with dependencies to limit their effects to those files. If a file appears as a dependency of `.IGNORE', then errors will be ignored while running the commands to update that file. Likewise if a file appears as a dependency of `.SILENT', then the commands to update that file will not be printed before they are run. (This change was made to conform to POSIX.2.) Version 3.71 * The automatic variables `$(@D)', `$(%D)', `$(*D)', `$(
