In Guile 1.8 there is no + support for internationalized character sets. In Guile 2.0+, scripts can be + encoded in UTF-8. + +* New command line option: --output-sync (-O) enables grouping of output by + target or by recursive make. This is useful during parallel builds to avoid + mixing output from different jobs together giving hard-to-understand + results. Original implementation by David Boyce <dsb@boyski.com>. + Reworked and enhanced by Frank Heckenbach <f.heckenbach@fh-soft.de>. + Windows support by Eli Zaretskii <eliz@gnu.org>. + +* New command line option: --trace enables tracing of targets. When enabled + the recipe to be invoked is printed even if it would otherwise be suppressed + by .SILENT or a "@" prefix character. Also before each recipe is run the + makefile name and linenumber where it was defined are shown as well as the + prerequisites that caused the target to be considered out of date. + +* New command line option argument: --debug now accepts a "n" (none) flag + which disables all debugging settings that are currently enabled. + +* New feature: The "job server" capability is now supported on Windows. + Implementation contributed by Troy Runkel <Troy.Runkel@mathworks.com> + +* New feature: The .ONESHELL capability is now supported on Windows. Support + added by Eli Zaretskii <eliz@gnu.org>. + +* New feature: "!=" shell assignment operator as an alternative to the + $(shell ...) function. Implemented for compatibility with BSD makefiles. + Note there are subtle differences between "!=" and $(shell ...). See the + description in the GNU make manual. + WARNING: Backward-incompatibility! + Variables ending in "!" previously defined as "variable!= value" will now be + interpreted as shell assignment. Change your assignment to add whitespace + between the "!" and "=": "variable! = value" + +* New feature: "::=" simple assignment operator as defined by POSIX in 2012. + This operator has identical functionality to ":=" in GNU make, but will be + portable to any implementation of make conforming to a sufficiently new + version of POSIX (see http://austingroupbugs.net/view.php?id=330). It is + not necessary to define the .POSIX target to access this operator. + +* New feature: Loadable objects + This version of GNU make contains a "technology preview": the ability to + load dynamic objects into the make runtime. These objects can be created by + the user and can add extended functionality, usable by makefiles. + +* New function: $(file ...) writes to a file. + +* New variable: $(GNUMAKEFLAGS) will be parsed for make flags, just like + MAKEFLAGS is. It can be set in the environment or the makefile, containing + GNU make-specific flags to allow your makefile to be portable to other + versions of make. Once this variable is parsed, GNU make will set it to the + empty string so that flags will not be duplicated on recursion. + +* New variable: `MAKE_HOST' gives the name of the host architecture + make was compiled for. This is the same value you see after 'Built for' + when running 'make --version'. + +* Behavior of MAKEFLAGS and MFLAGS is more rigorously defined. All simple + flags are grouped together in the first word of MAKEFLAGS. No options that + accept arguments appear in the first word. If no simple flags are present + MAKEFLAGS begins with a space. Flags with both short and long versions + always use the short versions in MAKEFLAGS. Flags are listed in + alphabetical order using ASCII ordering. MFLAGS never begins with "- ". + +* Setting the -r and -R options in MAKEFLAGS inside a makefile now works as + expected, removing all built-in rules and variables, respectively. + +* If a recipe fails, the makefile name and linenumber of the recipe are shown. + +* A .RECIPEPREFIX setting is remembered per-recipe and variables expanded + in that recipe also use that recipe prefix setting. + +* In -p output, .RECIPEPREFIX settings are shown and all target-specific + variables are output as if in a makefile, instead of as comments. + +* On MS-Windows, recipes that use ".." quoting will no longer force + invocation of commands via temporary batch files and stock Windows + shells, they will be short-circuited and invoked directly. (In + other words, " is no longer a special character for stock Windows + shells.) This avoids hitting shell limits for command length when + quotes are used, but nothing else in the command requires the shell. + This change could potentially mean some minor incompatibilities in + behavior when the recipe uses quoted string on shell command lines. + + +Version 3.82 (28 Jul 2010) A complete list of bugs fixed in this version is available here: @@ -18,14 +122,6 @@ http://sv.gnu.org/bugs/index.php?group=make&report_id=111&fix_release_id=104&set * Compiling GNU make now requires a conforming ISO C 1989 compiler and standard runtime library. -* WARNING: Future backward-incompatibility! - Wildcards are not documented as returning sorted values, but up to and - including this release the results have been sorted and some makefiles are - apparently depending on that.
