INSTALL

   1
   2                 Git installation
   3
   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
   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
  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.
  15
  16 Alternatively you can use autoconf generated ./configure script to
  17 set 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

  25 Issues 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
  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".  Unless you specify otherwise, you'll get the SHA1
  60           library from here.
  61
  62           If you don't have openssl, you can use one of the SHA1 libraries
  63           that come with git (git includes the one from Mozilla, and has
  64           its own PowerPC and ARM optimized ones too - see the Makefile).
  65
  66         - "libcurl" and "curl" executable.  git-http-fetch and
  67           git-fetch use them.  If you do not use http
  68           transfer, you are probably OK if you do not have
  69           them.
  70
  71         - expat library; git-http-push uses it for remote lock
  72           management over DAV.  Similar to "curl" above, this is optional.
  73
  74         - "wish", the Tcl/Tk windowing shell is used in gitk to show the
  75           history graphically, and in git-gui.
  76
  77         - "ssh" is used to push and pull over the net
  78
  79         - "perl" and POSIX-compliant shells are needed to use most of
  80           the barebone Porcelainish scripts.
  81
  82         - "cpio" is used by git-clone when doing a local (possibly
  83           hardlinked) clone.
  84
  85  - Some platform specific issues are dealt with Makefile rules,
  86    but depending on your specific installation, you may not
  87    have all the libraries/tools needed, or you may have
  88    necessary libraries at unusual locations.  Please look at the
  89    top of the Makefile to see what can be adjusted for your needs.
  90    You can place local settings in config.mak and the Makefile
  91    will include them.  Note that config.mak is not distributed;
  92    the name is reserved for local settings.
  93
  94  - To build and install documentation suite, you need to have
  95    the asciidoc/xmlto toolchain.  Because not many people are
  96    inclined to install the tools, the default build target
  97    ("make all") does _not_ build them.
  98
  99    Building and installing the info file additionally requires
 100    makeinfo and docbook2X.  Version 0.8.3 is known to work.
 101
 102    The documentation is written for AsciiDoc 7, but "make
 103    ASCIIDOC8=YesPlease doc" will let you format with AsciiDoc 8.
 104
 105    Alternatively, pre-formatted documentation are available in
 106    "html" and "man" branches of the git repository itself.  For
 107    example, you could:
 108
 109         $ mkdir manual && cd manual
 110         $ git init
 111         $ git fetch-pack git://git.kernel.org/pub/scm/git/git.git man html |
 112           while read a b
 113           do
 114             echo $a >.git/$b
 115           done
 116         $ cp .git/refs/heads/man .git/refs/heads/master
 117         $ git checkout
 118
 119    to checkout the pre-built man pages.  Also in this repository:
 120
 121         $ git checkout html
 122
 123    would instead give you a copy of what you see at:
 124
 125         http://www.kernel.org/pub/software/scm/git/docs/
 126
 127    It has been reported that docbook-xsl version 1.72 and 1.73 are
 128    buggy; 1.72 misformats manual pages for callouts, and 1.73 needs
 129    the patch in contrib/patches/docbook-xsl-manpages-charmap.patch
