Hello Chris, your question is an Automake one, not an Autoconf one.

If yes, they should rather be in MAINTAINERCLEANFILES than in CLEANFILES, and if no, they should rather be built in the build tree not the source tree, so that read-only source trees can work. If that is possible with antlr, that is. > # These instructions are a "hack" used to instruct make that all of the > # BUILT_SOURCES are produced when invoking the above rule and they are > # not to be run in parallel > $(srcdir)/TCExpressionLexer.hpp: $(srcdir)/TCExpressionLexer.cpp > $(srcdir)/TCExpressionLexerTokenTypes.hpp: $(srcdir)/TCExpressionLexer.cpp > $(srcdir)/TCExpressionParser.cpp: $(srcdir)/TCExpressionLexer.cpp > $(srcdir)/TCExpressionParser.hpp: $(srcdir)/TCExpressionLexer.cpp > $(srcdir)/TCExpressionTreeWalker.cpp: $(srcdir)/TCExpressionLexer.cpp > $(srcdir)/TCExpressionTreeWalker.hpp: $(srcdir)/TCExpressionLexer.cpp Why are these dependencies necessary?
