Previously, while automake did *not* distribute C source and header
files derived from non-distributed Lex sources, it still caused
them to be removed only by "make maintainer-clean" only, and not by
simply "make clean" or "make distclean".
This caused "make distcheck" to fail, unless the developer put
those generated .c files in CLEANFILES or in DISTCLEANFILES by
hand.
This change fixes this issue, by making non-distributed `.c' files
generated by non-distributed Lex sources cleaned by "make clean".
A similar problem for Yacc support had been fixed with the commit
v1.11-263-ged2c8bc.

lex tests: make test on Lex dependency tracking more "semantic"
* Changes to Yacc support:
- - C source and header files derived from non-distributed Yacc sources are
- now removed by "make clean", not only by "make maintainer-clean".
+ - C source and header files derived from non-distributed Yacc and/or
+ Lex sources are now removed by a simple "make clean" (while they were
+ previously removed only "make maintainer-clean").
- Slightly backward-incompatible change, relevant only for use of Yacc
with C++: the extensions of the header files produced by the Yacc
# compile a lex file.
sub lang_lex_target_hook
{
- my ($self, $aggregate, $output, $input) = @_;
- # If the files are built in the build directory, then we want to
- # remove them with `make clean'. If they are in srcdir they
- # shouldn't be touched. However, we can't determine this
- # statically, and the GNU rules say that yacc/lex output files
- # should be removed by maintainer-clean. So that's what we do.
- $clean_files{$output} = MAINTAINER_CLEAN;
+ my ($self, $aggregate, $output, $input, %transform) = @_;
+ # The GNU rules say that yacc/lex output files should be removed
+ # by maintainer-clean. However, if the files are not distributed,
+ # then we want to remove them with "make clean"; otherwise,
+ # "make distcheck" will fail.
+ $clean_files{$output} = $transform{'DIST_SOURCE'} ? MAINTAINER_CLEAN : CLEAN;
}
# This is a helper for both lex and yacc.
