Using make target name in generated prerequisite

问题:

All I am wanting to do something along the lines of...

some_file.out : ..... ver_$(basename $@).ver:
   .....

The $@ does not expand as expected but only in the rule header. Inside the body of the rule all uses of ver_$(basename $@).ver expand as desired. How would I modify this to make it work as desired?

You have ellipses eliding too many important parts of your example to provide a full solution. However, one option is to use static pattern rules, like this:

some_file.out : %.out : ver_%.ver
        ...

If that isn't sufficient you can use secondary expansion, but that's a bigger hammer.
