1 This directory contains the %VERSION% release of GNU Make.
3 See the file NEWS for the user-visible changes from previous releases.
4 In addition, there have been bugs fixed.
6 Please check the system-specific notes below for any caveats related to
9 For general building and installation instructions, see the file INSTALL.
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.
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.
23 GNU Make is free software. See the file COPYING for copying conditions.
29 GNU Make can be obtained in many different ways. See a description here:
31 http://www.gnu.org/software/software.html
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.

66 You can send GNU make bug reports to <bug-make@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.

71 project to submit new problem reports or search for existing ones:

97 The GNU make source repository is available via anonymous CVS from the
98 GNU Subversions CVS server; look here for details:
100 http://savannah.gnu.org/cvs/?group=make
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.
111 System-specific Notes
112 ---------------------
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.
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
122 http://mail.gnu.org/archive/html/bug-autoconf/2003-10/msg00190.html
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.)
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.
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.
151 - See README.customs for details on integrating GNU make with the
152 Customs distributed build environment from the Pmake distribution.
154 - See readme.vms for details about GNU Make on OpenVMS.
156 - See README.Amiga for details about GNU Make on AmigaDOS.
158 - See README.W32 for details about GNU Make on Windows NT, 95, or 98.
160 - See README.DOS for compilation instructions on MS-DOS and MS-Windows
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
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
