Re: Bug#214592: dry-run of double-colon rules?

Hi,

      This has been reported by a debian user.

In some cases, GNU make ignores some double-colon rules when dry-run.

Assumed this Makefile is given

 all: foo.1 foo.2
 foo.1:
         touch foo.1
 foo.2:
         touch foo.2

 install.man:: foo.1
         @echo install foo.1

 install.man:: foo.2
         @echo install foo.2

 install.man::
         @echo install done

I've got the following results

 % make
 touch foo.1
 touch foo.2
 % make -n install.man
 echo install foo.1
 echo install done

I expect "echo install foo.2", but make dry-run shows not to
run "install foo.2".
However, if I run make actually

 % make install.man
 install foo.1
 install foo.2
 install done

"install foo.2" is executed.  Is this an intentional behavior or a bug
of GNU make?

Note that pmake run as I expected

 % pmake -n install.man
 echo install foo.1
 echo install foo.2
 echo install done
 % pmake install.man
 install foo.1
 install foo.2
 install done

I know if I add ".PHONY: install.man" to Makefile, GNU make works as
well, but I experienced this by Makefile generated by xmkmf so that no
PHONY target was defined.
