Introduction to Git
Git is a free and open source,
distributed version control system designed to handle everything
from small to very large projects with speed and efficiency. Every
Git clone is a full-fledged
repository with complete history and full revision tracking
capabilities, not dependent on network access or a central server.
Branching and merging are fast and easy to do. Git is used for version control of files, much
like tools such as mercurial-7.2, Bazaar, Subversion-1.14.5, CVS, Perforce, and Team
Foundation Server.

This package is known to build and work
properly using an LFS 13.0 platform.

Additional Downloads
Git Dependencies
Recommended
cURL-8.18.0 (needed to use Git over http, https, ftp or ftps)
Optional
Apache-2.4.66 (for some tests), Fcron-3.4.0 (runtime, for
scheduling git
maintenance jobs), GnuPG-2.5.17
(runtime, may be used to sign Git
commits or tags, or verify the signatures of them), OpenSSH-10.2p1 (runtime, needed to use
Git over ssh), Subversion-1.14.5 with Perl bindings
(runtime, for git
svn), Tk-8.6.17 (gitk, a simple Git repository viewer, uses Tk at runtime), Valgrind-3.26.0,
Authen::SASL (runtime,
for git send-email),
IO-Socket-SSL-2.098 (runtime, for
git send-email to
connect to a SMTP server with SSL encryption),
and Systemd-259.1 (runtime, rebuilt with Linux-PAM-1.7.2, for scheduling git maintenance jobs)
Optional (to create the man pages, html docs and other docs)
xmlto-0.0.29 and asciidoc-10.2.1, and also dblatex (for the PDF
version of the user manual), and docbook2x to create info
pages
Installation of Git
Install Git by running the
following commands:
./configure --prefix=/usr \
--with-gitconfig=/etc/gitconfig \
--with-python=python3 \
--with-libpcre2 &&
make
You can build the man pages and/or html docs, or use downloaded
ones. If you choose to build them, use the next two instructions.
If you have installed asciidoc-10.2.1 you can create the html
version of the man pages and other docs:
make html
If you have installed asciidoc-10.2.1 and xmlto-0.0.29 you can
create the man pages:
make man
The test suite can be run in parallel mode. To run the test suite,
issue: GIT_UNZIP=nonexist make test
-k. The GIT_UNZIP
setting prevents the test suite from using unzip, we need it because in BLFS
unzip is a symlink to
bsdunzip which does
not satisfy the assumption of some tests cases. If any test case
fails, the list of failed tests can be shown via make -C t aggregate-results.
Now, as the root user:
make perllibdir=/usr/lib/perl5/5.42/site_perl install
If you created the man pages and/or html docs
Install the man pages as the root
user:
make install-man
Install the html docs as the root
user:
make htmldir=/usr/share/doc/git-2.53.0 install-html
If you downloaded the man pages and/or html docs
If you downloaded the man pages untar them as the root user:
tar -xf ../git-manpages-2.53.0.tar.xz \
-C /usr/share/man --no-same-owner --no-overwrite-dir
If you downloaded the html docs untar them as the root user:
mkdir -vp /usr/share/doc/git-2.53.0 &&
tar -xf ../git-htmldocs-2.53.0.tar.xz \
-C /usr/share/doc/git-2.53.0 --no-same-owner --no-overwrite-dir &&
find /usr/share/doc/git-2.53.0 -type d -exec chmod 755 {} \; &&
find /usr/share/doc/git-2.53.0 -type f -exec chmod 644 {} \;
Reorganize text and html in the html-docs (both methods)
For both methods, the html-docs include a lot of plain text files.
Reorganize the files as the root
user:
mkdir -vp /usr/share/doc/git-2.53.0/man-pages/{html,text} &&
mv /usr/share/doc/git-2.53.0/{git*.adoc,man-pages/text} &&
mv /usr/share/doc/git-2.53.0/{git*.,index.,man-pages/}html &&
mkdir -vp /usr/share/doc/git-2.53.0/technical/{html,text} &&
mv /usr/share/doc/git-2.53.0/technical/{*.adoc,text} &&
mv /usr/share/doc/git-2.53.0/technical/{*.,}html &&
mkdir -vp /usr/share/doc/git-2.53.0/howto/{html,text} &&
mv /usr/share/doc/git-2.53.0/howto/{*.adoc,text} &&
mv /usr/share/doc/git-2.53.0/howto/{*.,}html &&
sed -i '/^<a href=/s|howto/|&html/|' /usr/share/doc/git-2.53.0/howto-index.html &&
sed -i '/^\* link:/s|howto/|&html/|' /usr/share/doc/git-2.53.0/howto-index.adoc
Command Explanations
--with-gitconfig=/etc/gitconfig: This
sets /etc/gitconfig as the file that
stores the default, system wide, Git settings.
--with-python=python3: Use
this switch to use Python 3,
instead of the EOL'ed Python 2.
Python is used for the git
p4 interface to Perforce repositories, and also
used in some tests.
--with-libpcre2: This
ensures building git
grep with the PCRE2 library installed in LFS, so
git grep will support
the --perl-regexp option.
tar -xf ../git-manpages-2.53.0.tar.gz
-C /usr/share/man --no-same-owner: This untars
git-manpages-2.53.0.tar.gz. The
-C option makes tar change directory to
/usr/share/man before it starts to
decompress the docs. The --no-same-owner option stops tar from preserving
the user and group details of the files. This is useful as that
user or group may not exist on your system; this could
(potentially) be a security risk.
mv /usr/share/doc/git-2.53.0
...: These commands move some of the files into
subfolders to make it easier to sort through the docs and find what
you're looking for.
find ... chmod ...:
These commands correct the permissions in the shipped documentation
tar file.
