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 all doc ;# as yourself 9 # make prefix=/usr install install-doc ;# 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 16Alternatively you can use autoconf generated ./configure script to 17set up install paths (via config.mak.autogen), so you can write instead 18 19 $ autoconf ;# as yourself if ./configure doesn't exist yet 20 $ ./configure --prefix=/usr ;# as yourself 21 $ make all doc ;# as yourself 22 # make install install-doc ;# as root 23 24 25Issues of note: 26 27 - git normally installs a helper script wrapper called "git", which 28 conflicts with a similarly named "GNU interactive tools" program. 29 30 Tough. Either don't use the wrapper script, or delete the old GNU 31 interactive tools. None of the core git stuff needs the wrapper, 32 it's just a convenient shorthand and while it is documented in some 33 places, you can always replace "git commit" with "git-commit" 34 instead. 35 36 But let's face it, most of us don't have GNU interactive tools, and 37 even if we had it, we wouldn't know what it does. I don't think it 38 has been actively developed since 1997, and people have moved over to 39 graphical file managers. 40 41 - You can use git after building but without installing if you 42 wanted to. Various git commands need to find other git 43 commands and scripts to do their work, so you would need to 44 arrange a few environment variables to tell them that their 45 friends will be found in your built source area instead of at 46 their standard installation area. Something like this works 47 for me: 48 49 GIT_EXEC_PATH=`pwd` 50 PATH=`pwd`:$PATH 51 GITPERLLIB=`pwd`/perl/blib/lib:`pwd`/perl/blib/arch/auto/Git 52 export GIT_EXEC_PATH PATH GITPERLLIB 53 54 - Git is reasonably self-sufficient, but does depend on a few external 55 programs and libraries: 56 57 - "zlib", the compression library. Git won't build without it. 58 59 - "openssl". The git-rev-list program uses bignum support from 60 openssl, and unless you specify otherwise, you'll also get the 61 SHA1 library from here. 62 63 If you don't have openssl, you can use one of the SHA1 libraries 64 that come with git (git includes the one from Mozilla, and has 65 its own PowerPC and ARM optimized ones too - see the Makefile). 66 67 - "libcurl" and "curl" executable. git-http-fetch and 68 git-fetch use them. If you do not use http 69 transfer, you are probably OK if you do not have 70 them. 71 72 - expat library; git-http-push uses it for remote lock 73 management over DAV. Similar to "curl" above, this is optional. 74 75 - "GNU diff" to generate patches. Of course, you don't _have_ to 76 generate patches if you don't want to, but let's face it, you'll 77 be wanting to. Or why did you get git in the first place? 78 79 Non-GNU versions of the diff/patch programs don't generally support 80 the unified patch format (which is the one git uses), so you 81 really do want to get the GNU one. Trust me, you will want to 82 do that even if it wasn't for git. There's no point in living 83 in the dark ages any more. 84 85 - "merge", the standard UNIX three-way merge program. It usually 86 comes with the "rcs" package on most Linux distributions, so if 87 you have a developer install you probably have it already, but a 88 "graphical user desktop" install might have left it out. 89 90 You'll only need the merge program if you do development using 91 git, and if you only use git to track other peoples work you'll 92 never notice the lack of it. 93 94 - "wish", the Tcl/Tk windowing shell is used in gitk to show the 95 history graphically 96 97 - "ssh" is used to push and pull over the net 98 99 - "perl" and POSIX-compliant shells are needed to use most of 100 the barebone Porcelainish scripts. 101 102 - "python" 2.3 or more recent; if you have 2.3, you may need 103 to build with "make WITH_OWN_SUBPROCESS_PY=YesPlease". 104 105 - Some platform specific issues are dealt with Makefile rules, 106 but depending on your specific installation, you may not 107 have all the libraries/tools needed, or you may have 108 necessary libraries at unusual locations. Please look at the 109 top of the Makefile to see what can be adjusted for your needs. 110 You can place local settings in config.mak and the Makefile 111 will include them. Note that config.mak is not distributed; 112 the name is reserved for local settings. 113 114 - To build and install documentation suite, you need to have the 115 asciidoc/xmlto toolchain. Alternatively, pre-formatted 116 documentation are available in "html" and "man" branches of the git 117 repository itself. For example, you could: 118 119 $ mkdir manual && cd manual 120 $ git init-db 121 $ git fetch-pack git://git.kernel.org/pub/scm/git/git.git man html | 122 while read a b 123 do 124 echo $a >.git/$b 125 done 126 $ cp .git/refs/heads/man .git/refs/heads/master 127 $ git checkout 128 129 to checkout the pre-built man pages. Also in this repository: 130 131 $ git checkout html 132 133 would instead give you a copy of what you see at: 134 135 http://www.kernel.org/pub/software/scm/git/docs/ 136
