Hmm, this is pretty much what I did. I have foo_SOURCES = foo/foo.c foo/foo_parse.y foo/foo_scan.l foo/foo_state.c in $(top_srcdir)/Makefile.am. I moved foo_parse.[ch], foo_scan.c from $(top_builddir) to $(top_srcdir)/foo. When I type "make", the files are generated in $(top_builddir); the files in $(top_srcdir)/foo are not updated. Moreover, "make distclean" in $(top_builddir) doesn't delete the generated files. I've also tried: * Copying ylwrap to $(top_srcdir). * Creating foo/Makefile.am, updating AC_CONFIG_FILES and rebuilding. Neither one helped. I assume the difference shouldn't be the fact that you generate C++ source. What else could affect the behavior? Which version of automake do you have? Do you have ylwrap in $(top_srcdir)?
