There is no way to do this, currently, in GNU make except through pattern rules. Just listing one pattern target with a bunch of non-pattern rules won't do it. > Is the above rule equivalent to the following rules? > > $(objpfx)stubs ../po/manual.pot: > $(make-target-directory) > touch $@ > > > $(objpfx)stamp%: > $(make-target-directory) > touch $@ Yes, exactly. If you run "make -p" you'll see that this is exactly how make has parsed that makefile into its internal database. -- ------------------------------------------------------------------------------- Paul D.
