You need some actual dependencies. Add something like this:
$(cxx_files): src/diary.xml
Pattern rules that don't have any actions are generally of limited
use, partly because make tends to ignore them.
Also, this makefile can get stuck. If src/diary.xml is up to date WRT
src/toto.stc but the cxx files are not, for whatever reason (like
somebody mangling the tree by hand), then make has nothing to do but
the cxx files won't get built. So it breaks.
One way to write this better is like this:
src/diary.xml $(cxx_files): cxx_stamp
cxx_stamp: src/toto.stc
gencxx src/toto.stc
touch cxx_stamp
CLEANFILES += cxx_stamp
I think that'll do what you want.
