| This directory contains the %VERSION% release of GNU Make. |
| |
| See the file NEWS for the user-visible changes from previous releases. |
| In addition, there have been bugs fixed. |
| |
| Please check the system-specific notes below for any caveats related to your |
| operating system. |
| |
| If you are trying to build GNU make from a Git clone rather than a downloaded |
| source distribution, see the README.git file for instructions. |
| |
| For source distribution building and installation instructions, see the file |
| INSTALL. |
| |
| If you need to build GNU Make and have no other 'make' program to use, you can |
| use the shell script 'build.sh' instead. To do this, first run 'configure' as |
| described in INSTALL. Then, instead of typing 'make' to build the program, |
| type 'sh build.sh'. This should compile the program in the current directory. |
| Then you will have a Make program that you can use for './make install', or |
| whatever else. |
| |
| Some systems' Make programs cannot process the Makefile for GNU Make. If you |
| get errors from your system's Make when building GNU Make, try using |
| 'build.sh' instead. |
| |
| |
| GNU Make is free software. See the file COPYING for copying conditions. |
| GNU Make is copyright by the Free Software Foundation. Copyright notices |
| condense sequential years into a range; e.g. "1987-1994" means all years |
| from 1987 to 1994 inclusive. |
| |
| Downloading |
| ----------- |
| |
| GNU Make can be obtained in many different ways. See a description here: |

| |
| |
| Documentation |
| ------------- |
| |
| GNU make is fully documented in the GNU Make manual, which is contained |
| in this distribution as the file make.texinfo. You can also find |
| on-line and preformatted (PostScript and DVI) versions at the FSF's web |
| site. There is information there about ordering hardcopy documentation. |

| |
| Development |
| ----------- |
| |
| GNU Make development is hosted by Savannah, the FSF's online development |
| management tool. Savannah is here: |
| |
| http://savannah.gnu.org |
| |
| And the GNU Make development page is here: |
| |
| http://savannah.gnu.org/projects/make/ |
| |
| You can find most information concerning the development of GNU Make at |
| this site. |

| |
| Bug Reporting |
| ------------- |
| |
| You can send GNU make bug reports to <[email protected]>. Please see the |
| section of the GNU make manual entitled 'Problems and Bugs' for |
| information on submitting useful and complete bug reports. |
| |
| You can also use the online bug tracking system in the Savannah GNU Make |
| project to submit new problem reports or search for existing ones: |
| |
| http://savannah.gnu.org/bugs/?group=make |

| |
| Git Access |
| ---------- |
| |
| The GNU make source repository is available via Git from the GNU Savannah Git |
| server; look here for details: |
| |
| http://savannah.gnu.org/git/?group=make |
| |
| Please note: you won't be able to build GNU make from Git without installing |
| appropriate maintainer's tools, such as GNU m4, automake, autoconf, Perl, GNU |
| make, and GCC. |
| |
| See the README.git file for instructions on how to build GNU make once these |
| tools are available. We make no guarantees about the contents or quality of |
| the latest code in the Git repository: it is not unheard of for code that is |
| known to be broken to be checked in. Use at your own risk. |
| |
| |
| System-specific Notes |
| --------------------- |
| |
| It has been reported that the XLC 1.2 compiler on AIX 3.2 is buggy such |
| that if you compile make with 'cc -O' on AIX 3.2, it will not work |
| correctly. It is said that using 'cc' without '-O' does work. |
| |
| The standard /bin/sh on SunOS 4.1.3_U1 and 4.1.4 is broken and cannot be |
| used to configure GNU make. Please install a different shell such as |
| bash or pdksh in order to run "configure". See this message for more |
| information: |
| http://mail.gnu.org/archive/html/bug-autoconf/2003-10/msg00190.html |
| |
| One area that is often a problem in configuration and porting is the code |
| to check the system's current load average. To make it easier to test and |
| debug this code, you can do 'make check-loadavg' to see if it works |
| properly on your system. (You must run 'configure' beforehand, but you |
| need not build Make itself to run this test.) |
| |
| Another potential source of porting problems is the support for large |
| files (LFS) in configure for those operating systems that provide it. |
| Please report any bugs that you find in this area. If you run into |
| difficulties, then as a workaround you should be able to disable LFS by |
| adding the '--disable-largefile' option to the 'configure' script. |
| |
| On systems that support micro- and nano-second timestamp values and |
| where stat(2) provides this information, GNU make will use it when |
| comparing timestamps to get the most accurate possible result. However, |
| note that many current implementations of tools that *set* timestamps do |
| not preserve micro- or nano-second granularity. This means that "cp -p" |
| and other similar tools (tar, etc.) may not exactly duplicate timestamps |
| with micro- and nano-second granularity on some systems. If your build |
| system contains rules that depend on proper behavior of tools like "cp |
| -p", you should consider using the .LOW_RESOLUTION_TIME pseudo-target to |
| force make to treat them properly. See the manual for details. |

| Ports |
| ----- |
| |
| - See README.customs for details on integrating GNU make with the |
| Customs distributed build environment from the Pmake distribution. |
| |
| - See README.VMS for details about GNU Make on OpenVMS. |
| |
| - See README.Amiga for details about GNU Make on AmigaDOS. |
| |
| - See README.W32 for details about GNU Make on Windows NT, 95, or 98. |
| |
| - See README.DOS for compilation instructions on MS-DOS and MS-Windows |
| using DJGPP tools. |
| |
| A precompiled binary of the MSDOS port of GNU Make is available as part |
| of DJGPP; see the WWW page http://www.delorie.com/djgpp/ for more |
| information. |
| |
| The Cygwin project maintains its own port of GNU make. That port may have |
| patches which are not present in this version. If you are using Cygwin |
| you should use their version of GNU make, and if you have questions about |
| it you should start by asking on those mailing lists and forums. |
| |
| Please note there are two _separate_ ports of GNU make for Microsoft |
| systems: a native Windows tool built with (for example) MSVC or Cygwin, |
| and a DOS-based tool built with DJGPP. Please be sure you are looking |
| at the right README! |
