1 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 8 $ make prefix=/usr ;# as yourself 9 # make prefix=/usr install ;# as root 10 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. 15 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 24 places, you can always replace "git commit" with "git-commit" 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). 46 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. 51 52 - expat library; git-http-push uses it for remote lock 53 management over DAV. Similar to "curl" above, this is optional. 54 55 - "GNU diff" to generate patches. Of course, you don't _have_ to 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 59 Non-GNU versions of the diff/patch programs don't generally support 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. 73 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
