Subject: [Qemu-devel] [PATCH] Add a stp file for usage from build directory
Date: Tue, 28 May 2013 13:44:29 -0400 [thread overview]
Message-ID: <1369763069-13689-1-git-send-email-alevy@redhat.com> (raw)
For systemtap the location of the process being tapped is crucial, as a
result the existing stp file requires installation for use.
There are now two files:
$(TARGET_DIR)/$(QEMU_PROG).stp-installed: copied to $(tapdir)/$(QEMU_PROG).stp
$(TARGET_DIR)/$(QEMU_PROG).stp: usable locally
To use:
stap -I $(TARGET_DIR) ..
