   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 info ;# as yourself
   9        # make prefix=/usr install install-doc install-info ;# 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        $ make configure ;# as yourself
  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   NOTE: As of gnuit-4.9.2, the GNU interactive tools package has been
  42         renamed. You can compile gnuit with the --disable-transition
  43         option and then it will not conflict with git.
  44
  45 - You can use git after building but without installing if you
  46   wanted to.  Various git commands need to find other git
  47   commands and scripts to do their work, so you would need to
  48   arrange a few environment variables to tell them that their
  49   friends will be found in your built source area instead of at
  50   their standard installation area.  Something like this works
  51   for me:
  52
  53        GIT_EXEC_PATH=`pwd`
  54        PATH=`pwd`:$PATH
  55        GITPERLLIB=`pwd`/perl/blib/lib
  56        export GIT_EXEC_PATH PATH GITPERLLIB
  57
  58 - Git is reasonably self-sufficient, but does depend on a few external
  59   programs and libraries:
  60
  61        - "zlib", the compression library. Git won't build without it.
  62
  63        - "openssl".  Unless you specify otherwise, you'll get the SHA1
  64          library from here.
  65
  66          If you don't have openssl, you can use one of the SHA1 libraries
  67          that come with git (git includes the one from Mozilla, and has
  68          its own PowerPC and ARM optimized ones too - see the Makefile).
  69
  70        - libcurl library; git-http-fetch and git-fetch use them.  You
  71          might also want the "curl" executable for debugging purposes.
  72          If you do not use http transfer, you are probably OK if you
  73          do not have them.
  74
  75        - expat library; git-http-push uses it for remote lock
  76          management over DAV.  Similar to "curl" above, this is optional.
  77
  78        - "wish", the Tcl/Tk windowing shell is used in gitk to show the
  79          history graphically, and in git-gui.
  80
  81        - "ssh" is used to push and pull over the net
  82
  83        - "perl" and POSIX-compliant shells are needed to use most of
  84          the barebone Porcelainish scripts.
  85
  86 - Some platform specific issues are dealt with Makefile rules,
  87   but depending on your specific installation, you may not
  88   have all the libraries/tools needed, or you may have
  89   necessary libraries at unusual locations.  Please look at the
  90   top of the Makefile to see what can be adjusted for your needs.
  91   You can place local settings in config.mak and the Makefile
  92   will include them.  Note that config.mak is not distributed;
  93   the name is reserved for local settings.
  94
  95 - To build and install documentation suite, you need to have
  96   the asciidoc/xmlto toolchain.  Because not many people are
  97   inclined to install the tools, the default build target
  98   ("make all") does _not_ build them.
  99
 100   Building and installing the info file additionally requires
 101   makeinfo and docbook2X.  Version 0.8.3 is known to work.
 102
 103   The documentation is written for AsciiDoc 7, but "make
 104   ASCIIDOC8=YesPlease doc" will let you format with AsciiDoc 8.
 105
 106   Alternatively, pre-formatted documentation are available in
 107   "html" and "man" branches of the git repository itself.  For
 108   example, you could:
 109
 110        $ mkdir manual && cd manual
 111        $ git init
 112        $ git fetch-pack git://git.kernel.org/pub/scm/git/git.git man html |
 113          while read a b
 114          do
 115            echo $a >.git/$b
 116          done
 117        $ cp .git/refs/heads/man .git/refs/heads/master
 118        $ git checkout
 119
 120   to checkout the pre-built man pages.  Also in this repository:
 121
 122        $ git checkout html
 123
 124   would instead give you a copy of what you see at:
 125
 126        http://www.kernel.org/pub/software/scm/git/docs/
 127
 128   It has been reported that docbook-xsl version 1.72 and 1.73 are
 129   buggy; 1.72 misformats manual pages for callouts, and 1.73 needs
 130   the patch in contrib/patches/docbook-xsl-manpages-charmap.patch
