Since commit 6cf378f
(docs: stop using asciidoc no-inline-literal),
we no longer support asciidoc versions less than 8.4.1,
which introduced inline literals. Note this in the INSTALL
document.

Git installation
|
|
|
|
Normally you can just do "make" followed by "make install", and that
|
|
will install the git programs in your own ~/bin/ directory. If you want
|
|
to do a global install, you can do
|
|
|
|
$ make prefix=/usr all doc info ;# as yourself
|
|
# make prefix=/usr install install-doc install-html install-info ;# as root
|
|
|
|
(or prefix=/usr/local, of course). Just like any program suite
|
|
that uses $prefix, the built results have some paths encoded,
|
|
which are derived from $prefix, so "make all; make prefix=/usr
|
|
install" would not work.
|
|
|
|
The beginning of the Makefile documents many variables that affect the way
|
|
git is built. You can override them either from the command line, or in a
|
|
config.mak file.
|
|
|
|
Alternatively you can use autoconf generated ./configure script to
|
|
set up install paths (via config.mak.autogen), so you can write instead
|
|
|
|
$ make configure ;# as yourself
|
|
$ ./configure --prefix=/usr ;# as yourself
|
|
$ make all doc ;# as yourself
|
|
# make install install-doc install-html;# as root
|
|
|
|
If you're willing to trade off (much) longer build time for a later
|
|
faster git you can also do a profile feedback build with
|
|
|
|
$ make prefix=/usr PROFILE=BUILD all
|
|
# make prefix=/usr PROFILE=BUILD install
|
|
|
|
This will run the complete test suite as training workload and then
|
|
rebuild git with the generated profile feedback. This results in a git
|
|
which is a few percent faster on CPU intensive workloads. This
|
|
may be a good tradeoff for distribution packagers.
|
|
|
|
Or if you just want to install a profile-optimized version of git into
|
|
your home directory, you could run:
|
|
|
|
$ make PROFILE=BUILD install
|
|
|
|
As a caveat: a profile-optimized build takes a *lot* longer since the
|
|
git tree must be built twice, and in order for the profiling
|
|
measurements to work properly, ccache must be disabled and the test
|
|
suite has to be run using only a single CPU. In addition, the profile
|
|
feedback build stage currently generates a lot of additional compiler
|
|
warnings.
|
|
|
|
Issues of note:
|
|
|
|
- Ancient versions of GNU Interactive Tools (pre-4.9.2) installed a
|
|
program "git", whose name conflicts with this program. But with
|
|
version 4.9.2, after long hiatus without active maintenance (since
|
|
around 1997), it changed its name to gnuit and the name conflict is no
|
|
longer a problem.
|
|
|
|
NOTE: When compiled with backward compatibility option, the GNU
|
|
Interactive Tools package still can install "git", but you can build it
|
|
with --disable-transition option to avoid this.
|
|
|
|
- You can use git after building but without installing if you want
|
|
to test drive it. Simply run git found in bin-wrappers directory
|
|
in the build directory, or prepend that directory to your $PATH.
|
|
This however is less efficient than running an installed git, as
|
|
you always need an extra fork+exec to run any git subcommand.
|
|
|
|
It is still possible to use git without installing by setting a few
|
|
environment variables, which was the way this was done
|
|
traditionally. But using git found in bin-wrappers directory in
|
|
the build directory is far simpler. As a historical reference, the
|
|
old way went like this:
|
|
|
|
GIT_EXEC_PATH=`pwd`
|
|
PATH=`pwd`:$PATH
|
|
GITPERLLIB=`pwd`/perl/blib/lib
|
|
export GIT_EXEC_PATH PATH GITPERLLIB
|
|
|
|
- Git is reasonably self-sufficient, but does depend on a few external
|
|
programs and libraries. Git can be used without most of them by adding
|
|
the approriate "NO_<LIBRARY>=YesPlease" to the make command line or
|
|
config.mak file.
|
|
|
|
- "zlib", the compression library. Git won't build without it.
|
|
|
|
- "ssh" is used to push and pull over the net.
|
|
|
|
- A POSIX-compliant shell is required to run many scripts needed
|
|
for everyday use (e.g. "bisect", "pull").
|
|
|
|
- "Perl" version 5.8 or later is needed to use some of the
|
|
features (e.g. preparing a partial commit using "git add -i/-p",
|
|
interacting with svn repositories with "git svn"). If you can
|
|
live without these, use NO_PERL. Note that recent releases of
|
|
Redhat/Fedora are reported to ship Perl binary package with some
|
|
core modules stripped away (see http://lwn.net/Articles/477234/),
|
|
so you might need to install additional packages other than Perl
|
|
itself, e.g. Time::HiRes.
|
|
|
|
- "openssl" library is used by git-imap-send to use IMAP over SSL.
|
|
If you don't need it, use NO_OPENSSL.
|
|
|
|
By default, git uses OpenSSL for SHA1 but it will use it's own
|
|
library (inspired by Mozilla's) with either NO_OPENSSL or
|
|
BLK_SHA1. Also included is a version optimized for PowerPC
|
|
(PPC_SHA1).
|
|
|
|
- "libcurl" library is used by git-http-fetch and git-fetch. You
|
|
might also want the "curl" executable for debugging purposes.
|
|
If you do not use http:// or https:// repositories, you do not
|
|
have to have them (use NO_CURL).
|
|
|
|
- "expat" library; git-http-push uses it for remote lock
|
|
management over DAV. Similar to "curl" above, this is optional
|
|
(with NO_EXPAT).
|
|
|
|
- "wish", the Tcl/Tk windowing shell is used in gitk to show the
|
|
history graphically, and in git-gui. If you don't want gitk or
|
|
git-gui, you can use NO_TCLTK.
|
|
|
|
- A gettext library is used by default for localizing Git. The
|
|
primary target is GNU libintl, but the Solaris gettext
|
|
implementation also works.
|
|
|
|
We need a gettext.h on the system for C code, gettext.sh (or
|
|
Solaris gettext(1)) for shell scripts, and libintl-perl for Perl
|
|
programs.
|
|
|
|
Set NO_GETTEXT to disable localization support and make Git only
|
|
use English. Under autoconf the configure script will do this
|
|
automatically if it can't find libintl on the system.
|
|
|
|
- Python version 2.6 or later is needed to use the git-p4
|
|
interface to Perforce.
|
|
|
|
- Some platform specific issues are dealt with Makefile rules,
|
|
but depending on your specific installation, you may not
|
|
have all the libraries/tools needed, or you may have
|
|
necessary libraries at unusual locations. Please look at the
|
|
top of the Makefile to see what can be adjusted for your needs.
|
|
You can place local settings in config.mak and the Makefile
|
|
will include them. Note that config.mak is not distributed;
|
|
the name is reserved for local settings.
|
|
|
|
- To build and install documentation suite, you need to have
|
|
the asciidoc/xmlto toolchain. Because not many people are
|
|
inclined to install the tools, the default build target
|
|
("make all") does _not_ build them.
|
|
|
|
"make doc" builds documentation in man and html formats; there are
|
|
also "make man", "make html" and "make info". Note that "make html"
|
|
requires asciidoc, but not xmlto. "make man" (and thus make doc)
|
|
requires both.
|
|
|
|
"make install-doc" installs documentation in man format only; there
|
|
are also "make install-man", "make install-html" and "make
|
|
install-info".
|
|
|
|
Building and installing the info file additionally requires
|
|
makeinfo and docbook2X. Version 0.8.3 is known to work.
|
|
|
|
Building and installing the pdf file additionally requires
|
|
dblatex. Version >= 0.2.7 is known to work.
|
|
|
|
All formats require at least asciidoc 8.4.1.
|
|
|
|
There are also "make quick-install-doc", "make quick-install-man"
|
|
and "make quick-install-html" which install preformatted man pages
|
|
and html documentation. To use these build targets, you need to
|
|
clone two separate git-htmldocs and git-manpages repositories next
|
|
to the clone of git itself.
|
|
|
|
It has been reported that docbook-xsl version 1.72 and 1.73 are
|
|
buggy; 1.72 misformats manual pages for callouts, and 1.73 needs
|
|
the patch in contrib/patches/docbook-xsl-manpages-charmap.patch
|
|
|
|
Users attempting to build the documentation on Cygwin may need to ensure
|
|
that the /etc/xml/catalog file looks something like this:
|
|
|
|
<?xml version="1.0"?>
|
|
<!DOCTYPE catalog PUBLIC
|
|
"-//OASIS//DTD Entity Resolution XML Catalog V1.0//EN"
|
|
"http://www.oasis-open.org/committees/entity/release/1.0/catalog.dtd"
|
|
>
|
|
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog">
|
|
<rewriteURI
|
|
uriStartString = "http://docbook.sourceforge.net/release/xsl/current"
|
|
rewritePrefix = "/usr/share/sgml/docbook/xsl-stylesheets"
|
|
/>
|
|
<rewriteURI
|
|
uriStartString="http://www.oasis-open.org/docbook/xml/4.5"
|
|
rewritePrefix="/usr/share/sgml/docbook/xml-dtd-4.5"
|
|
/>
|
|
</catalog>
|
|
|
|
This can be achieved with the following two xmlcatalog commands:
|
|
|
|
xmlcatalog --noout \
|
|
--add rewriteURI \
|
|
http://docbook.sourceforge.net/release/xsl/current \
|
|
/usr/share/sgml/docbook/xsl-stylesheets \
|
|
/etc/xml/catalog
|
|
|
|
xmlcatalog --noout \
|
|
--add rewriteURI \
|
|
http://www.oasis-open.org/docbook/xml/4.5/xsl/current \
|
|
/usr/share/sgml/docbook/xml-dtd-4.5 \
