Subject: Warnings without -Wno-unused
Date: Wed, 08 Mar 2006 10:27:00 -0000 [thread overview]
Message-ID: <20060308102702.GA8502@in.ibm.com> (raw)
Hi,
I used Frank's syscall.open example from the systemtap tutorial,
used the -k option and wrote a custom makefile to build the module
later in the /tmp dir. Here is the output:
-----

As you see, the warnings are benign (currently) and are supressed 'cos of
-Wno-unused in the Makefile generated by stap. But we should revisit this
issue sometime (sooner rather than later) and fixup wherever possible.
Do we already have a bugzilla for this? If not, should one be opened?
