r1993 r2591 1 1 GNU make NEWS -*-indented-text-*- 2 2 History of user-visible changes. 3 1 April 20063 28 July 2010 4 4 5 5 See the end of this file for copyrights and conditions. … … 11 11 12 12 13 Version 3.81.90 13 Version 3.82 14 15 A complete list of bugs fixed in this version is available here: 16 17 http://sv.gnu.org/bugs/index.php?group=make&report_id=111&fix_release_id=104&set=custom 14 18 15 19 * Compiling GNU make now requires a conforming ISO C 1989 compiler and 16 20 standard runtime library. 21 22 * WARNING: Future backward-incompatibility! 23 Wildcards are not documented as returning sorted values, but up to and 24 including this release the results have been sorted and some makefiles are 25 apparently depending on that. In the next release of GNU make, for 26 performance reasons, we may remove that sorting. If your makefiles 27 require sorted results from wildcard expansions, use the $(sort ...) 28 function to request it explicitly. 29 30 * WARNING: Backward-incompatibility! 31 The POSIX standard for make was changed in the 2008 version in a 32 fundamentally incompatible way: make is required to invoke the shell as if 33 the '-e' flag were provided. Because this would break many makefiles that 34 have been written to conform to the original text of the standard, the 35 default behavior of GNU make remains to invoke the shell with simply '-c'. 36 However, any makefile specifying the .POSIX special target will follow the 37 new POSIX standard and pass '-e' to the shell. See also .SHELLFLAGS 38 below. 39 40 * WARNING: Backward-incompatibility! 41 The '$?' variable now contains all prerequisites that caused the target to 42 be considered out of date, even if they do not exist (previously only 43 existing targets were provided in $?). 44 45 * WARNING: Backward-incompatibility! 46 As a result of parser enhancements, three backward-compatibility issues 47 exist: first, a prerequisite containing an "=" cannot be escaped with a 48 backslash any longer. You must create a variable containing an "=" and 49 use that variable in the prerequisite. Second, variable names can no 50 longer contain whitespace, unless you put the whitespace in a variable and 51 use the variable. Third, in previous versions of make it was sometimes 52 not flagged as an error for explicit and pattern targets to appear in the 53 same rule. Now this is always reported as an error. 54 55 * WARNING: Backward-incompatibility! 56 The pattern-specific variables and pattern rules are now applied in the 57 shortest stem first order instead of the definition order (variables 58 and rules with the same stem length are still applied in the definition 59 order). This produces the usually-desired behavior where more specific 60 patterns are preferred. To detect this feature search for 'shortest-stem' 61 in the .FEATURES special variable. 62 63 * WARNING: Backward-incompatibility! 64 The library search behavior has changed to be compatible with the standard 65 linker behavior. Prior to this version for prerequisites specified using 66 the -lfoo syntax make first searched for libfoo.so in the current 67 directory, vpath directories, and system directories. If that didn't yield 68 a match, make then searched for libfoo.a in these directories. Starting 69 with this version make searches first for libfoo.so and then for libfoo.a 70 in each of these directories in order. 71 72 * New command line option: --eval=STRING causes STRING to be evaluated as 73 makefile syntax (akin to using the $(eval ...) function). The evaluation 74 is performed after all default rules and variables are defined, but before 75 any makefiles are read. 17 76 18 77 * New special variable: .RECIPEPREFIX allows you to reset the recipe 19 78 introduction character from the default (TAB) to something else. The 20 79 first character of this variable value is the new recipe introduction 21 character. If the variable is set to the empty string, TAB is used 22 again. It can be set and reset at will; rules will be parsed 23 according to the current value. 80 character. If the variable is set to the empty string, TAB is used again. 81 It can be set and reset at will; recipes will use the value active when 82 they were first parsed. To detect this feature check the value of 83 $(.RECIPEPREFIX). 84 85 * New special variable: .SHELLFLAGS allows you to change the options passed 86 to the shell when it invokes recipes. By default the value will be "-c" 87 (or "-ec" if .POSIX is set). 88 89 * New special target: .ONESHELL instructs make to invoke a single instance 90 of the shell and provide it with the entire recipe, regardless of how many 91 lines it contains. As a special feature to allow more straightforward 92 conversion of makefiles to use .ONESHELL, any recipe line control 93 characters ('@', '+', or '-') will be removed from the second and 94 subsequent recipe lines. This happens _only_ if the SHELL value is deemed 95 to be a standard POSIX-style shell. If not, then no interior line control 96 characters are removed (as they may be part of the scripting language used 97 with the alternate SHELL). 98 99 * New variable modifier 'private': prefixing a variable assignment with the 100 modifier 'private' suppresses inheritance of that variable by 101 prerequisites. This is most useful for target- and pattern-specific 102 variables. 103 104 * New make directive: 'undefine' allows you to undefine a variable so that 105 it appears as if it was never set. Both $(flavor) and $(origin) functions 106 will return 'undefined' for such a variable. To detect this feature search 107 for 'undefine' in the .FEATURES special variable. 108 109 * The parser for variable assignments has been enhanced to allow multiple 110 modifiers ('export', 'override', 'private') on the same line as variables, 111 including define/endef variables, and in any order. Also, it is possible 112 to create variables and targets named as these modifiers. 113 114 * The 'define' make directive now allows a variable assignment operator 115 after the variable name, to allow for simple, conditional, or appending 116 multi-line variable assignment. 24 117 25 118 … … 60 153 61 154 * WARNING: Backward-incompatibility! 62 63 155 In order to comply with POSIX, the way in which GNU make processes 64 156 backslash-newline sequences in recipes has changed.
