   3 These notes intend to help people working on the CVS versions of
   4 Bison.

   6 * Requirements
   7
   8 Only the sources are installed in the CVS repository (to ease the
   9 maintenance, merges etc.), therefore you will have to get the latest
  10 stable versions of the maintainer tools we depend upon, including:
  11
  12 - Automake <http://www.gnu.org/software/automake/>
  13 - Autoconf <http://www.gnu.org/software/autoconf/>
  14 - Flex <http://www.gnu.org/software/flex/>
  15 - Gettext <http://www.gnu.org/software/gettext/>
  16 - Gzip <http://www.gnu.org/software/gzip/>
  17 - Tar <http://www.gnu.org/software/tar/>
  18 - Wget <http://www.gnu.org/software/wget/>
  19
  20 As of this writing, the latest stable version of Gzip is 1.2.4 but we
  21 suggest using test version 1.3.5 (or later, if one becomes available).
  22
  23 Valgrind <http://valgrind.org/> is also highly recommended, if
  24 Valgrind supports your architecture.
  25
  26 Bison is written using Bison grammars, so there are bootstrapping
  27 issues.  The bootstrap script attempts to discover when the C code
  28 generated from the grammars is out of date, and to bootstrap with an
  29 out-of-date version of the C code, but the process is not foolproof.
  30 Also, you may run into similar problems yourself if you modify Bison.
  31
  32 Only building the initial full source tree will be a bit painful,
  33 later, a plain `cvs update -P && make' should be sufficient.
  34
  35 * First CVS checkout
  36
  37 Obviously, if you are reading these notes, you did manage to check out
  38 Bison from CVS.  For the records, you will find all the relevant
  39 information on:
  40
  41         http://savannah.gnu.org/cvs/?group_id=56
  42
  43 The next step is asking the installation of all the missing files:
  44
  45         $ ./bootstrap
  46
  47 And there you are!  Just
  48
  49         $ ./configure && make && make check
  50
  51 At this point, there should be no difference between your local copy,
  52 and the CVS master copy:
  53
  54         $ cvs diff
  55
  56 should output no difference.
  57
  58 Enjoy!
