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

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.

16Issues of note:
17
18 - git normally installs a helper script wrapper called "git", which
19 conflicts with a similarly named "GNU interactive tools" program.
20
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
215a7ad1 24 places, you can always replace "git commit" with "git-commit"
c538d2d3

25 instead.
26
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.
31
32 - Git is reasonably self-sufficient, but does depend on a few external
33 programs and libraries:
34
35 - "zlib", the compression library. Git won't build without it.
36
37 - "openssl". The git-rev-list program uses bignum support from
38 openssl, and unless you specify otherwise, you'll also get the
39 SHA1 library from here.
40
41 If you don't have openssl, you can use one of the SHA1 libraries
42 that come with git (git includes the one from Mozilla, and has
43 its own PowerPC-optimized one too - see the Makefile), and you
44 can avoid the bignum support by excising git-rev-list support
45 for "--merge-order" (by hand).

47 - "libcurl" and "curl" executable. git-http-fetch and
48 git-fetch use them. If you do not use http

49 transfer, you are probabaly OK if you do not have
50 them.

52 - expat library; git-http-push uses it for remote lock
53 management over DAV. Similar to "curl" above, this is optional.
54
1c107dc4 55 - "GNU diff" to generate patches. Of course, you don't _have_ to
c538d2d3
LT
56 generate patches if you don't want to, but let's face it, you'll
57 be wanting to. Or why did you get git in the first place?
58
1c107dc4 59 Non-GNU versions of the diff/patch programs don't generally support
c538d2d3
LT
60 the unified patch format (which is the one git uses), so you
61 really do want to get the GNU one. Trust me, you will want to
62 do that even if it wasn't for git. There's no point in living
63 in the dark ages any more.
64
65 - "merge", the standard UNIX three-way merge program. It usually
66 comes with the "rcs" package on most Linux distributions, so if
67 you have a developer install you probably have it already, but a
68 "graphical user desktop" install might have left it out.
69
70 You'll only need the merge program if you do development using
71 git, and if you only use git to track other peoples work you'll
72 never notice the lack of it.

74 - "wish", the TCL/Tk windowing shell is used in gitk to show the
75 history graphically
76
77 - "ssh" is used to push and pull over the net
