| 1 | This directory contains the 3.79.1 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. |

| 26 | Documentation |
|---|
| 27 | ------------- |
|---|
| 28 | |
|---|
| 29 | GNU make is fully documented in the GNU Make manual, which is contained |
|---|
| 30 | in this distribution as the file make.texinfo. You can also find |
|---|
| 31 | on-line and preformatted (PostScript and DVI) versions at the FSF's web |
|---|
| 32 | site. There is information there about ordering hardcopy documentation. |

|---|
| 36 | http://www.gnu.org/manual/manual.html |
|---|
| 37 | |
|---|
| 38 | You can also find the latest versions of GNU Make from there. |

|---|
| 41 | Bug Reporting |
|---|
| 42 | ------------- |
|---|
| 43 | |
|---|
| 44 | You can send GNU make bug reports to <bug-make@gnu.org>. Please see the |
|---|
| 45 | section of the GNU make manual entitled `Problems and Bugs' for |
|---|
| 46 | information on submitting useful and complete bug reports. |
|---|
| 47 | |
|---|
| 48 | You can also use the FSF's online bug tracking system to submit new |
|---|
| 49 | problem reports or search for existing ones. A web interface is |
|---|
| 50 | available here: |
|---|
| 51 | |
|---|
| 52 | http://www-gnats.gnu.org:8080/cgi-bin/wwwgnats.pl |
|---|
| 53 | |
|---|
| 54 | Use the Category "make". |

| 64 | CVS Access |
|---|
| 65 | ---------- |
|---|
| 66 | |
|---|
| 67 | The GNU make source repository is available via anonymous CVS from the |
|---|
| 68 | GNU Subversions CVS server; look here for details: |
|---|
| 69 | |
|---|
| 70 | http://www.gnu.org/software/devel.html |
|---|
| 71 | |
|---|
| 72 | Please note: you won't be able to build GNU make from CVS without |
|---|
| 73 | installing appropriate maintainer's tools, such as automake, autoconf, |
|---|
| 74 | GNU make, and GCC. There are no instructions on this included with the |
|---|
| 75 | tree, so you must be familiar with the installation and use of these |
|---|
| 76 | tools. We make no guarantees about the contents or quality of the |
|---|
| 77 | latest code in the CVS repository: it is not unheard of for code that is |
|---|
| 78 | known to be broken to be checked in. Use at your own risk. |
|---|
| 79 | |
|---|

|---|
| 84 | - See README.customs for details on integrating GNU make with the |
|---|
| 85 | Customs distributed build environment from the Pmake distribution. |
|---|
| 86 | |
|---|
| 87 | - See readme.vms for details about GNU Make on OpenVMS. |
|---|
| 88 | |
|---|
| 89 | - See README.Amiga for details about GNU Make on AmigaDOS. |
|---|
| 90 | |
|---|
| 91 | - See README.W32 for details about GNU Make on Windows NT, 95, or 98. |
|---|
| 92 | |
|---|
| 93 | - See README.DOS for compilation instructions on MS-DOS and MS-Windows |
|---|
| 94 | using DJGPP tools. |
|---|
| 95 | |
|---|
| 96 | A precompiled binary of the MSDOS port of GNU Make is available as part |
|---|
| 97 | of DJGPP; see the WWW page http://www.delorie.com/djgpp/ for more |
|---|
| 98 | information. |
|---|
| 99 | |
|---|
| 100 | Please note there are two _separate_ ports of GNU make for Microsoft |
|---|
| 101 | systems: a native Windows tool built with (for example) MSVC or Cygwin, |
|---|
| 102 | and a DOS-based tool built with DJGPP. Please be sure you are looking |
|---|
| 103 | at the right README! |

| 106 | System-specific Notes |
|---|
| 107 | --------------------- |
|---|
| 108 | |
|---|
| 109 | It has been reported that the XLC 1.2 compiler on AIX 3.2 is buggy such |
|---|
| 110 | that if you compile make with `cc -O' on AIX 3.2, it will not work correctly. |
|---|
| 111 | It is said that using `cc' without `-O' does work. |
|---|
| 112 | |
|---|
| 113 | One area that is often a problem in configuration and porting is the code |
|---|
| 114 | to check the system's current load average. To make it easier to test and |
|---|
| 115 | debug this code, you can do `make check-loadavg' to see if it works |
|---|
| 116 | properly on your system. (You must run `configure' beforehand, but you |
|---|
| 117 | need not build Make itself to run this test.) |
|---|
| 118 | |
|---|
| 119 | Another potential source of porting problems is the support for large |
|---|
| 120 | files (LFS) in configure for those operating systems that provide it. |
|---|
| 121 | Please report any bugs that you find in this area. If you run into |
|---|
| 122 | difficulties, then as a workaround you should be able to disable LFS by |
|---|
| 123 | adding the `--disable-largefile' option to the `configure' script. |
|---|
| 124 | |
|---|
| 125 | On systems that support micro- and nano-second timestamp values and |
|---|
| 126 | where stat(2) provides this information, GNU make will use it when |
|---|
| 127 | comparing timestamps to get the most accurate possible result. However, |
|---|
| 128 | at the moment there is no system call (that I'm aware of) that will |
|---|
| 129 | allow you to *set* a timestamp to a micro- or nano-second granularity. |
|---|
| 130 | This means that "cp -p" and other similar tools (tar, etc.) cannot |
|---|
| 131 | exactly duplicate timestamps with micro- and nano-second granularity. |
|---|
| 132 | If your build system contains rules that depend on proper behavior of |
|---|
| 133 | tools like "cp -p", you should configure make to not use micro- and |
|---|
| 134 | nano-second timestamps with the --disable-nsec-timestamps flag. |
|---|
