   3 These notes intend to help people working on the checked-out sources.
   4 These requirements do not apply when building from a distribution tarball.

   6 * Requirements
   7
   8 We've opted to keep only the highest-level sources in the repository.
   9 This eases our maintenance burden, (fewer merges etc.), but imposes more
  10 requirements on anyone wishing to build from the just-checked-out sources.
  11 For example, you have to use the latest stable versions of the maintainer
  12 tools we depend upon, including:
  13
  14 - Automake <http://www.gnu.org/software/automake/>
  15 - Autoconf <http://www.gnu.org/software/autoconf/>
  16 - Flex <http://www.gnu.org/software/flex/>
  17 - Gettext <http://www.gnu.org/software/gettext/>
  18 - Gzip <http://www.gnu.org/software/gzip/>
  19 - Perl <http://www.cpan.org/>
  20 - Rsync <http://samba.anu.edu.au/rsync/>
  21 - Tar <http://www.gnu.org/software/tar/>
  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  28 generated from the grammars is out of date, and to bootstrap with an
  29 out-of-date version of the C code, but the process is not foolproof.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, after synchronizing from the repository a plain `make' should
  34 be sufficient.
  35
  36 * First checkout
  37
  38 Obviously, if you are reading these notes, you did manage to check out
  39 this package from the repository.  For the record, you will find all the
  40 relevant information on:
  41
  42         http://savannah.gnu.org/cvs/?group_id=56
  43
  44 The next step is to get other files needed to build, which are
  45 extracted from other source packages:
  46
  47         $ ./bootstrap
  48
  49 And there you are!  Just
  50
  51         $ ./configure
  52         $ make
  53         $ make check
  54
  55 At this point, there should be no difference between your local copy,
  56 and the master copy:
  57
  58         $ cvs diff
  59
  60 should output no difference.
  61
  62 Enjoy!
