This directory contains the 4.1 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.
|
||
|
||
For general 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 are broken and 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 <bug-make@gnu.org>. 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
|
||
|
||
If you need help using GNU make, try these forums:
|
||
|
||
help-make@gnu.org
|
||
help-utils@gnu.org
|
||

|

|
||
|
||
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 hints 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.
|
||
|
||
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!
