2 Git installation
3
4Normally you can just do "make" followed by "make install", and that
5will install the git programs in your own ~/bin/ directory. If you want
6to do a global install, you can do
7
98e79f63 8 $ make prefix=/usr all doc info ;# as yourself
414851a4 9 # make prefix=/usr install install-doc install-html install-info ;# as root

11(or prefix=/usr/local, of course). Just like any program suite
12that uses $prefix, the built results have some paths encoded,
13which are derived from $prefix, so "make all; make prefix=/usr
14install" would not work.

16Alternatively you can use autoconf generated ./configure script to
17set up install paths (via config.mak.autogen), so you can write instead
18
3900145e 19 $ make configure ;# as yourself
55667714
JN
20 $ ./configure --prefix=/usr ;# as yourself
21 $ make all doc ;# as yourself

25Issues of note:

27 - Ancient versions of GNU Interactive Tools (pre-4.9.2) installed a
28 program "git", whose name conflicts with this program. But with
29 version 4.9.2, after long hiatus without active maintenance (since
30 around 1997), it changed its name to gnuit and the name conflict is no
31 longer a problem.
32
25032ccd 33 NOTE: When compiled with backward compatibility option, the GNU
a958d8ed
JH
34 Interactive Tools package still can install "git", but you can build it
35 with --disable-transition option to avoid this.

37 - You can use git after building but without installing if you
38 wanted to. Various git commands need to find other git
39 commands and scripts to do their work, so you would need to
40 arrange a few environment variables to tell them that their
41 friends will be found in your built source area instead of at
42 their standard installation area. Something like this works
43 for me:
44
45 GIT_EXEC_PATH=`pwd`
46 PATH=`pwd`:$PATH
f7661ce0 47 GITPERLLIB=`pwd`/perl/blib/lib
6fcca938 48 export GIT_EXEC_PATH PATH GITPERLLIB

50 - Git is reasonably self-sufficient, but does depend on a few external
51 programs and libraries:
52
53 - "zlib", the compression library. Git won't build without it.
54
726f9bce
JH
55 - "openssl". Unless you specify otherwise, you'll get the SHA1
56 library from here.
c538d2d3
LT
57
58 If you don't have openssl, you can use one of the SHA1 libraries
59 that come with git (git includes the one from Mozilla, and has
765ac8ec 60 its own PowerPC and ARM optimized ones too - see the Makefile).
c538d2d3 61

62 - libcurl library; git-http-fetch and git-fetch use them. You
63 might also want the "curl" executable for debugging purposes.
64 If you do not use http transfer, you are probably OK if you
65 do not have them.
c538d2d3 66
3402f1d6
JH
67 - expat library; git-http-push uses it for remote lock
68 management over DAV. Similar to "curl" above, this is optional.
69
addf88e4 70 - "wish", the Tcl/Tk windowing shell is used in gitk to show the
726f9bce 71 history graphically, and in git-gui.

72
73 - "ssh" is used to push and pull over the net
3cab3594
JH
74
75 - "perl" and POSIX-compliant shells are needed to use most of
25032ccd 76 the bare-bones Porcelainish scripts.

78 - Some platform specific issues are dealt with Makefile rules,
79 but depending on your specific installation, you may not
80 have all the libraries/tools needed, or you may have
81 necessary libraries at unusual locations. Please look at the
82 top of the Makefile to see what can be adjusted for your needs.

83 You can place local settings in config.mak and the Makefile
84 will include them. Note that config.mak is not distributed;
85 the name is reserved for local settings.

87 - To build and install documentation suite, you need to have
88 the asciidoc/xmlto toolchain. Because not many people are
89 inclined to install the tools, the default build target
98e79f63
DK
90 ("make all") does _not_ build them.
91

92 "make doc" builds documentation in man and html formats; there are
93 also "make man", "make html" and "make info". Note that "make html"
94 requires asciidoc, but not xmlto. "make man" (and thus make doc)
95 requires both.
96
97 "make install-doc" installs documentation in man format only; there
98 are also "make install-man", "make install-html" and "make
99 install-info".
100
98e79f63
DK
101 Building and installing the info file additionally requires
102 makeinfo and docbook2X. Version 0.8.3 is known to work.
103
104 The documentation is written for AsciiDoc 7, but "make
105 ASCIIDOC8=YesPlease doc" will let you format with AsciiDoc 8.
a90918e8 106
414851a4 107 Alternatively, pre-formatted documentation is available in
a90918e8
JH
108 "html" and "man" branches of the git repository itself. For
109 example, you could:

BF
110
111 $ mkdir manual && cd manual
5c94f87e 112 $ git init
efc7fa53 113 $ git fetch-pack git://git.kernel.org/pub/scm/git/git.git man html |
eff351c9
BF
114 while read a b
115 do
116 echo $a >.git/$b
117 done
118 $ cp .git/refs/heads/man .git/refs/heads/master
119 $ git checkout
120
121 to checkout the pre-built man pages. Also in this repository:
122
123 $ git checkout html
124
125 would instead give you a copy of what you see at:
126
127 http://www.kernel.org/pub/software/scm/git/docs/
2ec39eda 128
b1a46b70
MH
129 There are also "make quick-install-doc", "make quick-install-man"
130 and "make quick-install-html" which install preformatted man pages
131 and html documentation.

132 This does not require asciidoc/xmlto, but it only works from within
133 a cloned checkout of git.git with these two extra branches, and will
134 not work for the maintainer for obvious chicken-and-egg reasons.

136 It has been reported that docbook-xsl version 1.72 and 1.73 are
137 buggy; 1.72 misformats manual pages for callouts, and 1.73 needs
138 the patch in contrib/patches/docbook-xsl-manpages-charmap.patch
