GNU make NEWS -- history of user-visible changes. 26 January 1995
Copyright (C) 1992, 1993, 1994, 1995 Free Software Foundation, Inc.
See the end for copying conditions.
Please send GNU make bug reports to bug-gnu-utils@prep.ai.mit.edu.
Version 3.73
* Converted to use Autoconf version 2, so `configure' has some new options.
See INSTALL for details.
* You can now send a SIGUSR1 signal to Make to toggle printing of debugging
output enable by -d, at any time during the run.
Version 3.72
* DJ Delorie has ported Make to MS-DOS using the GO32 extender.
He is maintaining the DOS port, not the GNU Make maintainer;
please direct bugs and questions for DOS to <djgpp@sun.soe.clarkson.edu>.
MS-DOS binaries are available for FTP from oak.oakland.edu:pub/msdos/djgpp.
* The `MAKEFLAGS' variable (in the environment or in a makefile) can now
contain variable definitions itself; these are treated just like
command-line variable definitions. Make will automatically insert any
variable definitions from the environment value of `MAKEFLAGS' or from
the command line, into the `MAKEFLAGS' value exported to children. The
`MAKEOVERRIDES' variable previously included in the value of `$(MAKE)'
for sub-makes is now included in `MAKEFLAGS' instead. As before, you can
reset `MAKEOVERRIDES' in your makefile to avoid putting all the variables
in the environment when its size is limited.
* If `.DELETE_ON_ERROR' appears as a target, Make will delete the target of
a rule if it has changed when its commands exit with a nonzero status,
just as when the commands get a signal.
* The automatic variable `$+' is new. It lists all the dependencies like
`$^', but preserves duplicates listed in the makefile. This is useful
for linking rules, where library files sometimes need to be listed twice
in the link order.
* You can now specify the `.IGNORE' and `.SILENT' special targets with
dependencies to limit their effects to those files. If a file appears as
a dependency of `.IGNORE', then errors will be ignored while running the
commands to update that file. Likewise if a file appears as a dependency
of `.SILENT', then the commands to update that file will not be printed
before they are run. (This change was made to conform to POSIX.2.)
Version 3.71
* The automatic variables `$(@D)', `$(%D)', `$(*D)', `$(<D)', `$(?D)', and
`$(^D)' now omit the trailing slash from the directory name. (This change
was made to comply with POSIX.2.)
* The source distribution now includes the Info files for the Make manual.
There is no longer a separate distribution containing Info and DVI files.
* You can now set the variables `binprefix' and/or `manprefix' in
Makefile.in (or on the command line when installing) to install GNU make
under a name other than `make' (i.e., ``make binprefix=g install''
installs GNU make as `gmake').
* The built-in Texinfo rules use the new variables `TEXI2DVI_FLAGS' for
flags to the `texi2dvi' script, and `MAKEINFO_FLAGS' for flags to the
Makeinfo program.
* The exit status of Make when it runs into errors is now 2 instead of 1.
The exit status is 1 only when using -q and some target is not up to date.
(This change was made to comply with POSIX.2.)
Version 3.70
* It is no longer a fatal error to have a NUL character in a makefile.
You should never put a NUL in a makefile because it can have strange
results, but otherwise empty lines full of NULs (such as produced by
the `xmkmf' program) will always work fine.
* The error messages for nonexistent included makefiles now refer to the
makefile name and line number where the `include' appeared, so Emacs's
C-x ` command takes you there (in case it's a typo you need to fix).
Version 3.69
* Implicit rule search for archive member references is now done in the
opposite order from previous versions: the whole target name `LIB(MEM)'
first, and just the member name and parentheses `(MEM)' second.
* Make now gives an error for an unterminated variable or function reference.
For example, `$(foo' with no matching `)' or `${bar' with no matching `}'.
* The new default variable `MAKE_VERSION' gives the version number of
Make, and a string describing the remote job support compiled in (if any).
Thus the value (in this release) is something like `3.69' or `3.69-Customs'.
* Commands in an invocation of the `shell' function are no longer run with
a modified environment like target commands are. As in versions before
3.68, they now run with the environment that `make' started with. We
have reversed the change made in version 3.68 because it turned out to
cause a paradoxical situation in cases like:
export variable = $(shell echo value)
When Make attempted to put this variable in the environment for a target
command, it would try expand the value by running the shell command
`echo value'. In version 3.68, because it constructed an environment
for that shell command in the same way, Make would begin to go into an
infinite loop and then get a fatal error when it detected the loop.
* The commands given for `.DEFAULT' are now used for phony targets with no
commands.
Version 3.68
* You can list several archive member names inside parenthesis:
`lib(mem1 mem2 mem3)' is equivalent to `lib(mem1) lib(mem2) lib(mem3)'.
* You can use wildcards inside archive member references. For example,
`lib(*.o)' expands to all existing members of `lib' whose names end in
`.o' (e.g. `lib(a.o) lib(b.o)'); `*.a(*.o)' expands to all such members
of all existing files whose names end in `.a' (e.g. `foo.a(a.o)
foo.a(b.o) bar.a(c.o) bar.a(d.o)'.
* A suffix rule `.X.a' now produces two pattern rules:
(%.o): %.X # Previous versions produced only this.
%.a: %.X # Now produces this as well, just like other suffixes.
* The new flag `--warn-undefined-variables' says to issue a warning message
whenever Make expands a reference to an undefined variable.
* The new `-include' directive is just like `include' except that there is
no error (not even a warning) for a nonexistent makefile.
* Commands in an invocation of the `shell' function are now run with a
modified environment like target commands are, so you can use `export' et
al to set up variables for them. They used to run with the environment
that `make' started with.
Version 3.66
* `make --version' (or `make -v') now exits immediately after printing
the version number.
Version 3.65
* Make now supports long-named members in `ar' archive files.
Version 3.64
* Make now supports the `+=' syntax for a variable definition which appends
to the variable's previous value. See the section `Appending More Text
to Variables' in the manual for full details.
* The new option `--no-print-directory' inhibits the `-w' or
`--print-directory' feature. Make turns on `--print-directory'
automatically if you use `-C' or `--directory', and in sub-makes; some
users have found this behavior undesirable.
* The built-in implicit rules now support the alternative extension
`.txinfo' for Texinfo files, just like `.texinfo' and `.texi'.
Version 3.63
* Make now uses a standard GNU `configure' script. See the new file
INSTALL for the new (and much simpler) installation procedure.
* There is now a shell script to build Make the first time, if you have no
other `make' program. `build.sh' is created by `configure'; see README.
* GNU Make now completely conforms to the POSIX.2 specification for `make'.
* Elements of the `$^' and `$?' automatic variables that are archive
member references now list only the member name, as in Unix and POSIX.2.
* You should no longer ever need to specify the `-w' switch, which prints
the current directory before and after Make runs. The `-C' switch to
change directory, and recursive use of Make, now set `-w' automatically.
* Multiple double-colon rules for the same target will no longer have their
commands run simultaneously under -j, as this could result in the two
commands trying to change the file at the same time and interfering with
one another.
* The `SHELL' variable is now never taken from the environment.
Each makefile that wants a shell other than the default (/bin/sh) must
set SHELL itself. SHELL is always exported to child processes.
This change was made for compatibility with POSIX.2.
* Make now accepts long options. There is now an informative usage message
that tells you what all the options are and what they do. Try `make --help'.
* There are two new directives: `export' and `unexport'. All variables are
no longer automatically put into the environments of the commands that
Make runs. Instead, only variables specified on the command line or in
the environment are exported by default. To export others, use:
export VARIABLE
or you can define variables with:
export VARIABLE = VALUE
or:
export VARIABLE := VALUE
You can use just:
export
or:
.EXPORT_ALL_VARIABLES:
to get the old behavior. See the node `Variables/Recursion' in the manual
for a full description.
* The commands from the `.DEFAULT' special target are only applied to
targets which have no rules at all, not all targets with no commands.
This change was made for compatibility with Unix make.
* All fatal error messages now contain `***', so they are easy to find in
compilation logs.
* Dependency file names like `-lNAME' are now replaced with the actual file
name found, as with files found by normal directory search (VPATH).
The library file `libNAME.a' may now be found in the current directory,
which is checked before VPATH; the standard set of directories (/lib,
/usr/lib, /usr/local/lib) is now checked last.
See the node `Libraries/Search' in the manual for full details.
* A single `include' directive can now specify more than one makefile to
include, like this:
include file1 file2
You can also use shell file name patterns in an `include' directive:
include *.mk
* The default directories to search for included makefiles, and for
libraries specified with `-lNAME', are now set by configuration.
* You can now use blanks as well as colons to separate the directories in a
search path for the `vpath' directive or the `VPATH' variable.
* You can now use variables and functions in the left hand side of a
variable assignment, as in "$(foo)bar = value".
* The `MAKE' variable is always defined as `$(MAKE_COMMAND) $(MAKEOVERRIDES)'.
The `MAKE_COMMAND' variable is now defined to the name with which make
was invoked.
* The built-in rules for C++ compilation now use the variables `$(CXX)' and
`$(CXXFLAGS)' instead of `$(C++)' and `$(C++FLAGS)'. The old names had
problems with shells that cannot have `+' in environment variable names.
* The value of a recursively expanded variable is now expanded when putting
it into the environment for child processes. This change was made for
compatibility with Unix make.
* A rule with no targets before the `:' is now accepted and ignored.
This change was made for compatibility with SunOS 4 make.
We do not recommend that you write your makefiles to take advantage of this.
* The `-I' switch can now be used in MAKEFLAGS, and are put there
automatically just like other switches.
Version 3.61
* Built-in rules for C++ source files with the `.C' suffix.
We still recommend that you use `.cc' instead.
* If commands are given too many times for a single target,
the last set given is used, and a warning message is printed.
* Error messages about makefiles are in standard GNU error format,
so C-x ` in Emacs works on them.
* Dependencies of pattern rules which contain no % need not actually exist
if they can be created (just like dependencies which do have a %).
Version 3.60
* A message is always printed when Make decides there is nothing to be done.
It used to be that no message was printed for top-level phony targets
(because "`phony' is up to date" isn't quite right). Now a different
message "Nothing to be done for `phony'" is printed in that case.
* Archives on AIX now supposedly work.
* When the commands specified for .DEFAULT are used to update a target,
the $< automatic variable is given the same value as $@ for that target.
This is how Unix make behaves, and this behavior is mandated by POSIX.2.
Version 3.59
* The -n, -q, and -t options are not put in the `MAKEFLAGS' and `MFLAG'
variables while remaking makefiles, so recursive makes done while remaking
makefiles will behave properly.
* If the special target `.NOEXPORT' is specified in a makefile,
only variables that came from the environment and variables
defined on the command line are exported.
Version 3.58
* Suffix rules may have dependencies (which are ignored).
Version 3.57
* Dependencies of the form `-lLIB' are searched for as /usr/local/lib/libLIB.a
as well as libLIB.a in /usr/lib, /lib, the current directory, and VPATH.
Version 3.55
* There is now a Unix man page for GNU Make. It is certainly not a replacement
for the Texinfo manual, but it documents the basic functionality and the
switches. For full documentation, you should still read the Texinfo manual.
Thanks to Dennis Morse of Stanford University for contributing the initial
version of this.
* Variables which are defined by default (e.g., `CC') will no longer be put
into the environment for child processes. (If these variables are reset by the
environment, makefiles, or the command line, they will still go into the
environment.)
* Makefiles which have commands but no dependencies (and thus are always
considered out of date and in need of remaking), will not be remade (if they
were being remade only because they were makefiles). This means that GNU
Make will no longer go into an infinite loop when fed the makefiles that
`imake' (necessary to build X Windows) produces.
* There is no longer a warning for using the `vpath' directive with an explicit
pathname (instead of a `%' pattern).
Version 3.51
* When removing intermediate files, only one `rm' command line is printed,
listing all file names.
* There are now automatic variables `$(^D)', `$(^F)', `$(?D)', and `$(?F)'.
These are the directory-only and file-only versions of `$^' and `$?'.
* Library dependencies given as `-lNAME' will use "libNAME.a" in the current
directory if it exists.
* The automatic variable `$($/)' is no longer defined.
* Leading `+' characters on a command line make that line be executed even
under -n, -t, or -q (as if the line contained `$(MAKE)').
* For command lines containing `$(MAKE)', `${MAKE}', or leading `+' characters,
only those lines are executed, not their entire rules.
(This is how Unix make behaves for lines containing `$(MAKE)' or `${MAKE}'.)
Version 3.50
* Filenames in rules will now have ~ and ~USER expanded.
* The `-p' output has been changed so it can be used as a makefile.
(All information that isn't specified by makefiles is prefaced with comment
characters.)
Version 3.49
* The % character can be quoted with backslash in implicit pattern rules,
static pattern rules, `vpath' directives, and `patsubst', `filter', and
`filter-out' functions. A warning is issued if a `vpath' directive's
pattern contains no %.
* The `wildcard' variable expansion function now expands ~ and ~USER.
* Messages indicating failed commands now contain the target name:
make: *** [target] Error 1
* The `-p' output format has been changed somewhat to look more like
makefile rules and to give all information that Make has about files.
Version 3.48
Version 3.47
* The `-l' switch with no argument removes any previous load-average limit.
* When the `-w' switch is in effect, and Make has updated makefiles,
it will write a `Leaving directory' messagfe before re-executing itself.
This makes the `directory change tracking' changes to Emacs's compilation
commands work properly.
Version 3.46
* The automatic variable `$*' is now defined for explicit rules,
as it is in Unix make.
Version 3.45
* The `-j' switch is now put in the MAKEFLAGS and MFLAGS variables when
specified without an argument (indicating infinite jobs).
The `-l' switch is not always put in the MAKEFLAGS and MFLAGS variables.
* Make no longer checks hashed directories after running commands.
The behavior implemented in 3.41 caused too much slowdown.
Version 3.44
* A dependency is NOT considered newer than its dependent if
they have the same modification time. The behavior implemented
in 3.43 conflicts with RCS.
Version 3.43
* Dependency loops are no longer fatal errors.
* A dependency is considered newer than its dependent if
they have the same modification time.
Version 3.42
* The variables F77 and F77FLAGS are now set by default to $(FC) and
$(FFLAGS). Makefiles designed for System V make may use these variables in
explicit rules and expect them to be set. Unfortunately, there is no way to
make setting these affect the Fortran implicit rules unless FC and FFLAGS
are not used (and these are used by BSD make).
Version 3.41
* Make now checks to see if its hashed directories are changed by commands.
Other makes that hash directories (Sun, 4.3 BSD) don't do this.
Version 3.39
* The `shell' function no longer captures standard error output.
Version 3.32
* A file beginning with a dot can be the default target if it also contains
a slash (e.g., `../bin/foo'). (Unix make allows this as well.)
Version 3.31
* Archive member names are truncated to 15 characters.
* Yet more USG stuff.
* Minimal support for Microport System V (a 16-bit machine and a
brain-damaged compiler). This has even lower priority than other USG
support, so if it gets beyond trivial, I will take it out completely.
* Revamped default implicit rules (not much visible change).
* The -d and -p options can come from the environment.
Version 3.30
* Improved support for USG and HPUX (hopefully).
* A variable reference like `$(foo:a=b)', if `a' contains a `%', is
equivalent to `$(patsubst a,b,$(foo))'.
* Defining .DEFAULT with no deps or commands clears its commands.
* New default implicit rules for .S (cpp, then as), and .sh (copy and make
executable). All default implicit rules that use cpp (even indirectly), use
$(CPPFLAGS).
Version 3.29
* Giving the -j option with no arguments gives you infinite jobs.
Version 3.28
* New option: "-l LOAD" says not to start any new jobs while others are
running if the load average is not below LOAD (a floating-point number).
* There is support in place for implementations of remote command execution
in Make. See the file remote.c.
Version 3.26
* No more than 10 directories will be kept open at once.
(This number can be changed by redefining MAX_OPEN_DIRECTORIES in dir.c.)
Version 3.25
* Archive files will have their modification times recorded before doing
anything that might change their modification times by updating an archive
member.
Version 3.20
* The `MAKELEVEL' variable is defined for use by makefiles.
Version 3.19
* The recursion level indications in error messages are much shorter than
they were in version 3.14.
Version 3.18
* Leading spaces before directives are ignored (as documented).
* Included makefiles can determine the default goal target.
(System V Make does it this way, so we are being compatible).
Version 3.14.
* Variables that are defaults built into Make will not be put in the
environment for children. This just saves some environment space and,
except under -e, will be transparent to sub-makes.
* Error messages from sub-makes will indicate the level of recursion.
* Hopefully some speed-up for large directories due to a change in the
directory hashing scheme.
* One child will always get a standard input that is usable.
* Default makefiles that don't exist will be remade and read in.
Version 3.13.
* Count parentheses inside expansion function calls so you can
have nested calls: `$(sort $(foreach x,a b,$(x)))'.
Version 3.12.
* Several bug fixes, including USG and Sun386i support.
* `shell' function to expand shell commands a la `
* If the `-d' flag is given, version information will be printed.
* The `-c' option has been renamed to `-C' for compatibility with tar.
* The `-p' option no longer inhibits other normal operation.
* Makefiles will be updated and re-read if necessary.
* Can now run several commands at once (parallelism), -j option.
* Error messages will contain the level of Make recursion, if any.
* The `MAKEFLAGS' and `MFLAGS' variables will be scanned for options after
makefiles are read.
* A double-colon rule with no dependencies will always have its commands run.
(This is how both the BSD and System V versions of Make do it.)
Version 3.05
(Changes from versions 1 through 3.05 were never recorded. Sorry.)

This directory contains the 3.72.8 test release of GNU Make.
All bugs reported for previous test releases have been fixed.
Some bugs surely remain.
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.
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.)
See the file NEWS for what has changed since previous releases.
GNU Make is fully documented in make.texinfo. See the section entitled
`Problems and Bugs' for information on submitting bug reports.
GNU Make is free software. See the file COPYING for copying conditions.
