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

8We've opted to keep only the highest-level sources in the repository.
9This eases our maintenance burden, (fewer merges etc.), but imposes more
10requirements on anyone wishing to build from the just-checked-out sources.
11For example, you have to use the latest stable versions of the maintainer
12tools we depend upon, including:

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/>
5b4aaf78 21- Tar <http://www.gnu.org/software/tar/>

23Valgrind <http://valgrind.org/> is also highly recommended, if
24Valgrind supports your architecture.

26Bison is written using Bison grammars, so there are bootstrapping
27issues. The bootstrap script attempts to discover when the C code
28generated from the grammars is out of date, and to bootstrap with an
29out-of-date version of the C code, but the process is not foolproof.
30Also, you may run into similar problems yourself if you modify Bison.

32Only building the initial full source tree will be a bit painful.
33Later, after synchronizing from the repository a plain `make' should
34be sufficient.

38Obviously, if you are reading these notes, you did manage to check out
6d8e724d 39this package from the repository. For the record, you will find all the
bbb44d83 40relevant information on:

44The next step is to get other files needed to build, which are
45extracted from other source packages:
d1a6f01e 46
01c56de4 47 $ ./bootstrap
d1a6f01e
AD
48
49And there you are! Just
50
bbb44d83
PE
51 $ ./configure
52 $ make
53 $ make check
d1a6f01e
AD

55At this point, there should be no difference between your local copy,
bbb44d83 56and the master copy:
d1a6f01e
AD
57
58 $ cvs diff
59
5b4aaf78 60should output no difference.
