-
-Obtaining Git 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 Git from the FSF's Savannah project
-<http://savannah.gnu.org/projects/make/>:
-
- $ git clone git://git.savannah.gnu.org/make.git
-
-
-Building From Git
------------------
-
-To build GNU make from Git, you will need Autoconf, Automake, and
-Gettext, and any tools that those utilities require (GNU m4, Perl,
-etc.). See the configure.in file to find the minimum versions of each
-of these tools. You will also need a copy of wget.
-
-When building from Git you must build in the source directory: "VPATH
-builds" from remote directories are not supported. Once you've created
-a distribution, of course, you can unpack it and do a VPATH build from
-there.
-
-After checking out the code, you will need to perform these steps to get
-to the point where you can run "make".
-
-
- 1) $ autoreconf -i
-
- This rebuilds all the things that need rebuilding, installing
- missing files as symbolic links.
-
- You may get warnings here about missing files like README, etc.
- Ignore them, they are harmless.
-
-
- 2) $ ./configure
-
- Generate a Makefile
-
-
- 3) $ make update
-
- Use wget to retrieve various other files that GNU make relies on,
- but does not keep in its own source tree.
-
- NB: You may need GNU make to correctly perform this step; if you use
- a platform-local make you may get problems with missing files in doc/.
-
-
-At this point you have successfully brought your Git 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.
-
-
-Windows builds from Git
------------------------
-
-If you have a UNIX emulation like CYGWIN you can opt to run the general
-build procedure above; it will work. Be sure to read
-README.W32.template for information on options you might want to use
-when running ./configure.
-
-If you can't or don't want to do that, then rename the file
-README.W32.template to README.W32 and follow those instructions.
-
-
-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!
-
-
-Steps to Release
-----------------
-
-Here are the things that need to be done (in more or less this order)
-before making an official release:
-
- * Update the configure.in file with the new release number.
- * Update the NEWS file with the release number and date.
- * In Savannah modify the "Value", "Rank", and "Description" values for the
- current "SCM" entry in both "Component Version" and "Fix Release" fields
- to refer to the new release, for "Bugs" and "Patches".
- * Update the Savannah bug list URL in the NEWS file to use the correct
- "Fixed Release" ID number.
- * In Savannah create a new entry for the "Component Version" and "Fix
- Release" fields:
- - Value: SCM
- - Rank: 20
- - Descr: Fixed in Git; will be available in the next version of Make.
- * Run "make distcheck" to be sure it all works.
- * git tag -u <GPGID> <VER> where GPGID is my GPG key fingerprint,
- and VER is the release version.
- * Push everything.
- * Create the new release in the Savannah "Bugs" Administration for
- both the "Component Version" and "Fixed Release" fields.
- * Create the new release in the Savannah "Patches" Administration for
- the "Fixed Release" field.
-
-
-Publishing a Package
---------------------
-
-In order to publish a package on the FSF FTP site, either the release
-site ftp://ftp.gnu.org, or the prerelease site ftp://alpha.gnu.org, you
-first need to have my GPG private key and my passphrase to unlock it.
-And, you can't have them! So there! But, just so I remember here's
-what to do:
-
- Make sure the "Steps to Release" are complete and committed and tagged.
-
- git clone git://git.savannah.gnu.org/make.git make-release
-
- cd make-release
-
- <run the commands above to build the release>
-
- make upload-alpha # for alpha.gnu.org (pre-releases)
- -OR-
- make upload-ftp # for ftp.gnu.org (official releases)
-
-Depending on your distribution (whether GnuPG is integrated with your keyring
-etc.) it will either pop up a window asking for your GPG key passphrase one
-time, or else it will use the CLI to ask for the GPG passphrase _THREE_ times.
-Sigh.
-
-
-For both final releases and pre-releases, send an email with the URL of
-the package to the GNU translation robot to allow the translators to
-work on it:
-
- <translation@iro.umontreal.ca>
-
-
-Where to Announce
------------------
-
-Create the announcement in a text file, then sign it with GPG.
-
- gpg --clearsign <announcement.txt>
-
-Upload to gnu.org, then login and send from my account there.
-
-To: bug-make@gnu.org, help-make@gnu.org, make-w32@gnu.org
-CC: info-gnu@gnu.org
-BCC: make-alpha@gnu.org
-
-Add a news item to the Savannah project site.
-
-Add an update to freshmeat.net.
-
-
-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 Git source checkout (assuming all the
-prerequisites are available of course).
-
-This list is eminently suitable for a quick swipe o' the mouse and a
-swift click o' mouse-2 into an xterm. Go for it!
-
-autoreconf -i
-./configure
-make update
-make
-make check
-
-Or, for a debugging version:
-
-autoreconf -i && ./configure CFLAGS=-g && make update && make && make check
-
-Or, all-in-one:
-
-autoreconf -i && ./configure && make update && make && make check
