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.
|
|
|
|
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.

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.
|
|
|
|
http://www.gnu.org/
|
|
http://www.gnu.org/doc/doc.html
|
|
http://www.gnu.org/manual/manual.html
|
|
|
|
You can also find the latest versions of GNU Make from there.
|
|
|
|
|
|
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 FSF's online bug tracking system to submit new
|
|
problem reports or search for existing ones. A web interface is
|
|
available here:
|
|
|
|
http://www-gnats.gnu.org:8080/cgi-bin/wwwgnats.pl
|
|
|
|
Use the Category "make".

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

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!

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.
|
|
|
|
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,
|
|
at the moment there is no system call (that I'm aware of) that will
|
|
allow you to *set* a timestamp to a micro- or nano-second granularity.
|
|
This means that "cp -p" and other similar tools (tar, etc.) cannot
|
|
exactly duplicate timestamps with micro- and nano-second granularity.
|
|
If your build system contains rules that depend on proper behavior of
|
|
tools like "cp -p", you should configure make to not use micro- and
|
|
nano-second timestamps with the --disable-nsec-timestamps flag.
