+We've opted to keep only the highest-level sources in the repository. This
+eases our maintenance burden, (fewer merges etc.), but imposes more
requirements on anyone wishing to build from the just-checked-out sources.
For example, you have to use the latest stable versions of the maintainer
tools we depend upon, including:
-- Automake <http://www.gnu.org/software/automake/>
- Autoconf <http://www.gnu.org/software/autoconf/>
+- Automake <http://www.gnu.org/software/automake/>
- Flex <http://www.gnu.org/software/flex/>
- Gettext <http://www.gnu.org/software/gettext/>
+- Graphviz <http://www.graphviz.org>
- Gzip <http://www.gnu.org/software/gzip/>
- Perl <http://www.cpan.org/>
- Rsync <http://samba.anu.edu.au/rsync/>
Valgrind <http://valgrind.org/> is also highly recommended, if it supports
your architecture.
-Bison is written using Bison grammars, so there are bootstrapping
-issues. The bootstrap script attempts to discover when the C code
-generated from the grammars is out of date, and to bootstrap with an
-out-of-date version of the C code, but the process is not foolproof.
-Also, you may run into similar problems yourself if you modify Bison.

-Only building the initial full source tree will be a bit painful.
-Later, after synchronizing from the repository a plain 'make' should
-be sufficient. Note, however, that when gnulib is updated, running
-'./bootstrap' again might be needed.

** First checkout
** make check
Use liberally.
+** TESTSUITEFLAGS
+
+The default is for make check to run all tests sequentially. This can be
+very time consumming when checking repeatedly or on slower setups. This can
+be sped up in two ways:
+
+Using -j, in a make-like fashion, for example:
+ $ make check TESTSUITEFLAGS='-j8'
+
+Running only the tests of a certain category, as specified in the AT files
+with AT_KEYWORDS([[category]]). Categories include:
+ - c++, for c++ parsers
+ - deprec, for tests concerning deprecated constructs.
+ - glr, for glr parsers
+ - java, for java parsers
+ - report, for automaton dumps
+
+To run a specific set of tests, use -k (for "keyword"). For example:
+ $ make check TESTSUITEFLAGS='-k c++'
+
+Both can be combined.
+
+** Typical errors
+If the test suite shows failures such as the following one
+
+ .../bison/lib/getopt.h:196:8: error: redefinition of 'struct option'
+ /usr/include/getopt.h:54:8: error: previous definition of 'struct option'
+
+it probably means that some file was compiled without
+AT_DATA_SOURCE_PROLOGUE. This error is due to the fact that our -I options
+pick up gnulib's replacement headers, such as getopt.h, and this will go
+wrong if config.h was not included first.
+
+See tests/local.at for details.

** make maintainer-check-valgrind
This target uses valgrind both to check bison, and the generated parsers.
