The directory was still using a local Makefile.am because it provides "scoped" Make variables: these examples are not meant to use the same CPPFLAGS etc. If we were to use the same -I set, we'd pick up gnulib's stdio.h for instance, which we do not want for these simple examples. Yet, as a result, the dependencies are less accurate, there is code duplication, etc. This is especially perceptible when trying to extract more examples from the documentation, as will be done in forthcoming changes. In order to make the tuning of CPPFLAGS easier, discard the predefined -I from Automake. * examples/calc++/Makefile.am: Rename as... * examples/calc++/local.mk: this. Adjust the paths which are now rooted in top_srcdir/top_builddir. Handle BISON_CXX_WORKS here, instead of the too crude previous approach that completely discarded the whole directory. ($(BISON)): Remove now useless bouncing recipe. (calc___CPPFLAGS): New. Stay away from -Ilib. * Makefile.am, configure.ac, examples/local.mk, * examples/calc++/test: Adjust. * configure.ac: Pass nostdinc to Automake. * src/local.mk, lib/local.mk (AM_CPPFLAGS): Move to... * Makefile.am: here. * src/local.mk, examples/calc++/Makefile.am (BISON, BISON_IN): Factor to... * Makefile.am: here. * tests/local.mk: Use it.

# See comments in build-aux/git-version-gen. However, we make .version depend
|
|
# on configure so that .version and VERSION/PACKAGE_VERSION stay in sync in the
|
|
# working copy (for example, when you run autoreconf && make). Allowing these
|
|
# to fall out of sync appears to have little potential to improve Bison build
|
|
# efficiency (even if we were to replace VERSION/PACKAGE_VERSION with .version
|
|
# everywhere possible). On the other hand, it could be harmful. For example,
|
|
# a developer might naively reference .version in a test case while the bison
|
|
# executable still compiles with VERSION, and so the test case might fail or
|
|
# pass incorrectly.
