|

| 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.
|
|---|

| 36 | Documentation
|
|---|
| 37 | -------------
|
|---|
| 38 |
|
|---|
| 39 | GNU make is fully documented in the GNU Make manual, which is contained

|---|
| 41 | on-line and preformatted (PostScript and DVI) versions at the FSF's web
|
|---|
| 42 | site. There is information there about ordering hardcopy documentation.

| 51 |
|
|---|
| 52 | GNU Make development is hosted by Savannah, the FSF's online development
|
|---|
| 53 | management tool. Savannah is here:

| 65 | Bug Reporting
|
|---|
| 66 | -------------
|
|---|
| 67 |
|
|---|
| 68 | You can send GNU make bug reports to <bug-make@gnu.org>. Please see the
|
|---|
| 69 | section of the GNU make manual entitled 'Problems and Bugs' for
|
|---|
| 70 | information on submitting useful and complete bug reports.
|
|---|
| 71 |
|
|---|
| 72 | You can also use the online bug tracking system in the Savannah GNU Make
|
|---|
| 73 | project to submit new problem reports or search for existing ones:

| 85 | Git Access
|
|---|
| 86 | ----------
|
|---|
| 87 |
|
|---|
| 88 | The GNU make source repository is available via Git from the
|
|---|
| 89 | GNU Savannah Git server; look here for details:
|
|---|
| 90 |
|
|---|
| 91 | http://savannah.gnu.org/git/?group=make
|
|---|
| 92 |
|
|---|
| 93 | Please note: you won't be able to build GNU make from Git without
|
|---|
| 94 | installing appropriate maintainer's tools, such as GNU m4, automake,
|
|---|
| 95 | autoconf, Perl, GNU make, and GCC. See the README.git file for hints on
|
|---|
| 96 | how to build GNU make once these tools are available. We make no
|
|---|
| 97 | guarantees about the contents or quality of the latest code in the Git
|
|---|
| 98 | repository: it is not unheard of for code that is known to be broken to
|
|---|
| 99 | be checked in. Use at your own risk.

| 102 | System-specific Notes
|
|---|
| 103 | ---------------------
|
|---|
| 104 |
|
|---|
| 105 | It has been reported that the XLC 1.2 compiler on AIX 3.2 is buggy such
|
|---|
| 106 | that if you compile make with 'cc -O' on AIX 3.2, it will not work
|
|---|
| 107 | correctly. It is said that using 'cc' without '-O' does work.
|
|---|
| 108 |
|
|---|
| 109 | The standard /bin/sh on SunOS 4.1.3_U1 and 4.1.4 is broken and cannot be
|
|---|
| 110 | used to configure GNU make. Please install a different shell such as
|
|---|
| 111 | bash or pdksh in order to run "configure". See this message for more
|
|---|
| 112 | information:
|
|---|
| 113 | http://mail.gnu.org/archive/html/bug-autoconf/2003-10/msg00190.html
|
|---|
| 114 |
|
|---|
| 115 | One area that is often a problem in configuration and porting is the code
|
|---|
| 116 | to check the system's current load average. To make it easier to test and
|
|---|
| 117 | debug this code, you can do 'make check-loadavg' to see if it works
|
|---|
| 118 | properly on your system. (You must run 'configure' beforehand, but you
|
|---|
| 119 | need not build Make itself to run this test.)
|
|---|
| 120 |
|
|---|
| 121 | Another potential source of porting problems is the support for large
|
|---|
| 122 | files (LFS) in configure for those operating systems that provide it.
|
|---|
| 123 | Please report any bugs that you find in this area. If you run into
|
|---|
| 124 | difficulties, then as a workaround you should be able to disable LFS by
|
|---|
| 125 | adding the '--disable-largefile' option to the 'configure' script.
|
|---|
| 126 |
|
|---|
| 127 | On systems that support micro- and nano-second timestamp values and
|
|---|
| 128 | where stat(2) provides this information, GNU make will use it when
|
|---|
| 129 | comparing timestamps to get the most accurate possible result. However,
|
|---|
| 130 | note that many current implementations of tools that *set* timestamps do
|
|---|
| 131 | not preserve micro- or nano-second granularity. This means that "cp -p"
|
|---|
| 132 | and other similar tools (tar, etc.) may not exactly duplicate timestamps
|
|---|
| 133 | with micro- and nano-second granularity on some systems. If your build
|
|---|
| 134 | system contains rules that depend on proper behavior of tools like "cp
|
|---|
| 135 | -p", you should consider using the .LOW_RESOLUTION_TIME pseudo-target to
|
|---|
| 136 | force make to treat them properly. See the manual for details.

|
|---|

|
|---|
| 143 | Customs distributed build environment from the Pmake distribution.
|
|---|
| 144 |
|
|---|
| 145 | - See README.VMS for details about GNU Make on OpenVMS.
|
|---|
| 146 |
|
|---|
| 147 | - See README.Amiga for details about GNU Make on AmigaDOS.
|
|---|
| 148 |
|
|---|
| 149 | - See README.W32 for details about GNU Make on Windows NT, 95, or 98.
|
|---|
| 150 |
|
|---|
| 151 | - See README.DOS for compilation instructions on MS-DOS and MS-Windows
|
|---|
| 152 | using DJGPP tools.
|
|---|
| 153 |
|
|---|
| 154 | A precompiled binary of the MSDOS port of GNU Make is available as part
|
|---|
| 155 | of DJGPP; see the WWW page http://www.delorie.com/djgpp/ for more
|
|---|
| 156 | information.
|
|---|
| 157 |
|
|---|
| 158 | Please note there are two _separate_ ports of GNU make for Microsoft
|
|---|
| 159 | systems: a native Windows tool built with (for example) MSVC or Cygwin,
|
|---|
| 160 | and a DOS-based tool built with DJGPP. Please be sure you are looking
|
|---|
| 161 | at the right README!
