This looks correct. > in $(top_srcdir)/Makefile.am. I moved foo_parse.[ch], foo_scan.c from > $(top_builddir) to $(top_srcdir)/foo.

What else could affect the behavior? Which version of automake > do you have? 1.9.6 > Do you have ylwrap in $(top_srcdir)? In my source tree, if I do, find . -name ylwrap nothing is returned. I'm assuming I don't have that. I don't even know what it is. OK, I feel terrible. After looking at my build setup, it appears that the FooGrammar.cxx file IS put into the build directory. However, the FooLexer.cxx file is put in the source directory like I recalled. When I move the FooGrammar.cxx file from the build directory to the src directory, automake still puts the generated file in the build directory. Is this the behavior you are seeing? I'm very sorry for the misinformation. Bob Rossi
