4 Normally you can just do "make" followed by "make install", and that
5 will install the git programs in your own ~/bin/ directory. If you want
6 to do a global install, you can do
8 $ make prefix=/usr all doc ;# as yourself
9 # make prefix=/usr install install-doc ;# as root
11 (or prefix=/usr/local, of course). Just like any program suite
12 that uses $prefix, the built results have some paths encoded,
13 which are derived from $prefix, so "make all; make prefix=/usr
14 install" would not work.
18 - git normally installs a helper script wrapper called "git", which
19 conflicts with a similarly named "GNU interactive tools" program.
21 Tough. Either don't use the wrapper script, or delete the old GNU
22 interactive tools. None of the core git stuff needs the wrapper,
23 it's just a convenient shorthand and while it is documented in some
24 places, you can always replace "git commit" with "git-commit"
27 But let's face it, most of us don't have GNU interactive tools, and
28 even if we had it, we wouldn't know what it does. I don't think it
29 has been actively developed since 1997, and people have moved over to
30 graphical file managers.
32 - You can use git after building but without installing if you
33 wanted to. Various git commands need to find other git
34 commands and scripts to do their work, so you would need to
35 arrange a few environment variables to tell them that their
36 friends will be found in your built source area instead of at
37 their standard installation area. Something like this works
42 GITPERLLIB=`pwd`/perl/blib/lib:`pwd`/perl/blib/arch/auto/Git
43 export GIT_EXEC_PATH PATH GITPERLLIB
45 - Git is reasonably self-sufficient, but does depend on a few external
46 programs and libraries:
48 - "zlib", the compression library. Git won't build without it.
50 - "openssl". The git-rev-list program uses bignum support from
51 openssl, and unless you specify otherwise, you'll also get the
52 SHA1 library from here.
54 If you don't have openssl, you can use one of the SHA1 libraries
55 that come with git (git includes the one from Mozilla, and has
56 its own PowerPC and ARM optimized ones too - see the Makefile).
58 - "libcurl" and "curl" executable. git-http-fetch and
59 git-fetch use them. If you do not use http
60 transfer, you are probabaly OK if you do not have
63 - expat library; git-http-push uses it for remote lock
64 management over DAV. Similar to "curl" above, this is optional.
66 - "GNU diff" to generate patches. Of course, you don't _have_ to
67 generate patches if you don't want to, but let's face it, you'll
68 be wanting to. Or why did you get git in the first place?
70 Non-GNU versions of the diff/patch programs don't generally support
71 the unified patch format (which is the one git uses), so you
72 really do want to get the GNU one. Trust me, you will want to
73 do that even if it wasn't for git. There's no point in living
74 in the dark ages any more.
76 - "merge", the standard UNIX three-way merge program. It usually
77 comes with the "rcs" package on most Linux distributions, so if
78 you have a developer install you probably have it already, but a
79 "graphical user desktop" install might have left it out.
81 You'll only need the merge program if you do development using
82 git, and if you only use git to track other peoples work you'll
83 never notice the lack of it.
85 - "wish", the TCL/Tk windowing shell is used in gitk to show the
88 - "ssh" is used to push and pull over the net
90 - "perl" and POSIX-compliant shells are needed to use most of
91 the barebone Porcelainish scripts.
93 - "python" 2.3 or more recent; if you have 2.3, you may need
94 to build with "make WITH_OWN_SUBPROCESS_PY=YesPlease".
96 - Some platform specific issues are dealt with Makefile rules,
97 but depending on your specific installation, you may not
98 have all the libraries/tools needed, or you may have
99 necessary libraries at unusual locations. Please look at the
100 top of the Makefile to see what can be adjusted for your needs.
101 You can place local settings in config.mak and the Makefile
102 will include them. Note that config.mak is not distributed;
103 the name is reserved for local settings.
105 - To build and install documentation suite, you need to have the
106 asciidoc/xmlto toolchain. Alternatively, pre-formatted
107 documentation are available in "html" and "man" branches of the git
108 repository itself. For example, you could:
110 $ mkdir manual && cd manual
112 $ git fetch-pack git://git.kernel.org/pub/scm/git/git.git man html |
117 $ cp .git/refs/heads/man .git/refs/heads/master
120 to checkout the pre-built man pages. Also in this repository:
