Incorporate "order-only" prerequisites patch. Wrote a test for it. The test shows what might be a bug in the code; I need to look at it more closely (anyway it doesn't behave as I expected). Also I haven't done the docs yet.

Obtaining CVS Code
|
|
------------------
|
|
|
|
This seems redundant, since if you're reading this you most likely have
|
|
already performed this step; however, for completeness, you can obtain
|
|
the GNU make source code via anonymous CVS from the FSF's Savannah
|
|
project <http://savannah.gnu.org/projects/make/>:
|
|
|
|
$ cvs -d:pserver:anoncvs@subversions.gnu.org:/cvsroot/make co make
|
|
|
|
You might want to use the "-z3" option to get compression, and you most
|
|
certainly will want the -P option to avoid unneeded directories
|
|
cluttering up your source. Personally I add these (as well as -dP for
|
|
update) to my ~/.cvsrc file.
|
|
|
|
|
|
If you have an older version of CVS, you might have to login first.
|
|
There is no password; just hit the ENTER key if you are asked for one.
|
|
|
|
|
|
Building From CVS
|
|
-----------------
|
|
|
|
To build GNU make from CVS, you will need Autoconf 2.53 (or better),
|
|
Automake 1.6.1 (or better), and Gettext 0.11.3-pre2 (or better), and any
|
|
tools that those utilities require (GNU m4, Perl, etc.). You will also
|
|
need a copy of wget.
|
|
|
|
After checking out the code, you will need to perform these steps to get
|
|
to the point where you can run "make".
|
|
|
|
|
|
1) $ autopoint
|
|
|
|
This will instantiate various m4 macros files, etc. in the config
|
|
and po directories.
|
|
|
|
|
|
2) $ aclocal -I config
|
|
|
|
Generate the proper aclocal.m4 file.
|
|
|
|
|
|
3) $ autoheader
|
|
|
|
Generate a "config.h.in" file from the contents of configure.in,
|
|
etc.
|
|
|
|
|
|
4) $ automake --add-missing
|
|
|
|
Add (symlink) missing files into the distribution, and generate
|
|
Makefile.in's from Makefile.am's.
|
|
|
|
You will see these perhaps unexpected messages (among others which
|
|
you should be expecting :)); just ignore them--I know what I'm doing
|
|
:).
|
|
|
|
Makefile.am: required file `./README' not found
|
|
configure.in:xxx: required file `./build.sh.in' not found
|
|
Makefile.am:xxx: automatically discovered file `getloadavg.c' should not be explicitly mentioned
|
|
|
|
|
|
5) $ autoconf
|
|
|
|
Generate a "configure" script from configure.in and acinclude.m4.
|
|
|
|
|
|
6) $ ./configure
|
|
|
|
Generate a Makefile
|
|
|
|
|
|
7) $ make update
|
|
|
|
Use wget to retrieve various other files that GNU make relies on,
|
|
but does not keep in its own source tree.
|
|
|
|
|
|
At this point you have successfully brought your CVS copy of the GNU
|
|
make source directory up to the point where it can be treated
|
|
more-or-less like the official package you would get from ftp.gnu.org.
|
|
That is, you can just run:
|
|
|
|
$ make && make check && make install
|
|
|
|
to build and install GNU make.
|
|
|
|
|
|
Creating a Package
|
|
------------------
|
|
|
|
Once you have performed the above steps (including the configuration and
|
|
build) you can create a GNU make package. This is very simple, just
|
|
run:
|
|
|
|
$ make dist-gzip
|
|
|
|
and, if you like:
|
|
|
|
$ make dist-bzip2
|
|
|
|
Even better, you should run this:
|
|
|
|
$ make distcheck
|
|
|
|
Which will build both .gz and .bz2 package files, then unpack them into
|
|
a temporary location, try to build them, and repack them, verifying that
|
|
everything works, you get the same results, _and_ no extraneous files
|
|
are left over after the "distclean" rule--whew!! Now, _that_ is why
|
|
converting to Automake is worth the trouble! A big "huzzah!" to Tom
|
|
T. and the AutoToolers!
|
|
|
|
|
|
That's it, you're done!
|
|

Appendix A - For The Brave
|
|
--------------------------
|
|
|
|
For those of you who trust me implicitly, or are just brave (or
|
|
foolhardy), here is a canned sequence of commands to build a GNU make
|
|
distribution package from a virgin CVS source checkout (assuming all the
|
|
prerequisites are available of course).
|
|
|
|
This list is eminently suitable for a quick swipe o' the old mouse and a
|
|
swift click o' mouse-2 into an xterm. I even grudgingly removed my use
|
|
of "advanced shell features" like {}. Go for it!
|
|
|
|
|
|
autopoint
|
|
aclocal -I config
|
|
autoheader
|
|
automake --add-missing
|
|
autoconf
|
|
./configure
|
|
make update
|
|
make
|
|
make check
|
|
make distcheck
|
