1 This directory contains the 3.81 release of GNU Make. 2 3 See the file NEWS for the user-visible changes from previous releases. 4 In addition, there have been bugs fixed. 5 6 Please check the system-specific notes below for any caveats related to 7 your operating system. 8 9 For general building and installation instructions, see the file INSTALL. 10 11 If you need to build GNU Make and have no other `make' program to use, 12 you can use the shell script `build.sh' instead. To do this, first run 13 `configure' as described in INSTALL. Then, instead of typing `make' to 14 build the program, type `sh build.sh'. This should compile the program 15 in the current directory. Then you will have a Make program that you can 16 use for `./make install', or whatever else. 17 18 Some systems' Make programs are broken and cannot process the Makefile for 19 GNU Make. If you get errors from your system's Make when building GNU 20 Make, try using `build.sh' instead. 21 22 23 GNU Make is free software. See the file COPYING for copying conditions. 24 25 26 Downloading 27 ----------- 28 29 GNU Make can be obtained in many different ways. See a description here: 30 31 http://www.gnu.org/software/software.html 32 33 34 Documentation 35 ------------- 36 37 GNU make is fully documented in the GNU Make manual, which is contained 38 in this distribution as the file make.texinfo. You can also find 39 on-line and preformatted (PostScript and DVI) versions at the FSF's web 40 site. There is information there about ordering hardcopy documentation. 41 42 http://www.gnu.org/ 43 http://www.gnu.org/doc/doc.html 44 http://www.gnu.org/manual/manual.html 45 46 47 Development 48 ----------- 49 50 GNU Make development is hosted by Savannah, the FSF's online development 51 management tool. Savannah is here: 52 53 http://savannah.gnu.org 54 55 And the GNU Make development page is here: 56 57 http://savannah.gnu.org/projects/make/ 58 59 You can find most information concerning the development of GNU Make at 60 this site. 61 62 63 Bug Reporting 64 ------------- 65 66 You can send GNU make bug reports to <bug-make (a] gnu.org>. Please see the 67 section of the GNU make manual entitled `Problems and Bugs' for 68 information on submitting useful and complete bug reports. 69 70 You can also use the online bug tracking system in the Savannah GNU Make 71 project to submit new problem reports or search for existing ones: 72 73 http://savannah.gnu.org/bugs/?group=make 74 75 If you need help using GNU make, try these forums: 76 77 help-make (a] gnu.org 78 help-utils (a] gnu.org 79 news:gnu.utils.help 80 news:gnu.utils.bug 81 82 http://savannah.gnu.org/support/?group=make 83 84 You may also find interesting patches to GNU Make available here: 85 86 http://savannah.gnu.org/patch/?group=make 87 88 Note these patches are provided by our users as a service and we make no 89 statements regarding their correctness. Please contact the authors 90 directly if you have a problem or suggestion for a patch available on 91 this page. 92 93 94 CVS Access 95 ---------- 96 97 The GNU make source repository is available via anonymous CVS from the 98 GNU Subversions CVS server; look here for details: 99 100 http://savannah.gnu.org/cvs/?group=make 101 102 Please note: you won't be able to build GNU make from CVS without 103 installing appropriate maintainer's tools, such as GNU m4, automake, 104 autoconf, Perl, GNU make, and GCC. See the README.cvs file for hints on 105 how to build GNU make once these tools are available. We make no 106 guarantees about the contents or quality of the latest code in the CVS 107 repository: it is not unheard of for code that is known to be broken to 108 be checked in. Use at your own risk. 109 110 111 System-specific Notes 112 --------------------- 113 114 It has been reported that the XLC 1.2 compiler on AIX 3.2 is buggy such 115 that if you compile make with `cc -O' on AIX 3.2, it will not work 116 correctly. It is said that using `cc' without `-O' does work. 117 118 The standard /bin/sh on SunOS 4.1.3_U1 and 4.1.4 is broken and cannot be 119 used to configure GNU make. Please install a different shell such as 120 bash or pdksh in order to run "configure". See this message for more 121 information: 122 http://mail.gnu.org/archive/html/bug-autoconf/2003-10/msg00190.html 123 124 One area that is often a problem in configuration and porting is the code 125 to check the system's current load average. To make it easier to test and 126 debug this code, you can do `make check-loadavg' to see if it works 127 properly on your system. (You must run `configure' beforehand, but you 128 need not build Make itself to run this test.) 129 130 Another potential source of porting problems is the support for large 131 files (LFS) in configure for those operating systems that provide it. 132 Please report any bugs that you find in this area. If you run into 133 difficulties, then as a workaround you should be able to disable LFS by 134 adding the `--disable-largefile' option to the `configure' script. 135 136 On systems that support micro- and nano-second timestamp values and 137 where stat(2) provides this information, GNU make will use it when 138 comparing timestamps to get the most accurate possible result. However, 139 note that many current implementations of tools that *set* timestamps do 140 not preserve micro- or nano-second granularity. This means that "cp -p" 141 and other similar tools (tar, etc.) may not exactly duplicate timestamps 142 with micro- and nano-second granularity on some systems. If your build 143 system contains rules that depend on proper behavior of tools like "cp 144 -p", you should consider using the .LOW_RESOLUTION_TIME pseudo-target to 145 force make to treat them properly. See the manual for details. 146 147 148 Ports 149 ----- 150 151 - See README.customs for details on integrating GNU make with the 152 Customs distributed build environment from the Pmake distribution. 153 154 - See readme.vms for details about GNU Make on OpenVMS. 155 156 - See README.Amiga for details about GNU Make on AmigaDOS. 157 158 - See README.W32 for details about GNU Make on Windows NT, 95, or 98. 159 160 - See README.DOS for compilation instructions on MS-DOS and MS-Windows 161 using DJGPP tools. 162 163 A precompiled binary of the MSDOS port of GNU Make is available as part 164 of DJGPP; see the WWW page http://www.delorie.com/djgpp/ for more 165 information. 166 167 Please note there are two _separate_ ports of GNU make for Microsoft 168 systems: a native Windows tool built with (for example) MSVC or Cygwin, 169 and a DOS-based tool built with DJGPP. Please be sure you are looking 170 at the right README! 171 172 174 ------------------------------------------------------------------------------- 175 Copyright (C) 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 176 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006 Free Software Foundation, 177 Inc. 178 This file is part of GNU Make. 179 180 GNU Make is free software; you can redistribute it and/or modify it under the 181 terms of the GNU General Public License as published by the Free Software 182 Foundation; either version 2, or (at your option) any later version. 183 184 GNU Make is distributed in the hope that it will be useful, but WITHOUT ANY 185 WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR 186 A PARTICULAR PURPOSE.
