As a work around I have been using a 3.12-rc0 rpm. Also trying to avoid needing the elfutils at the moment, so I am running some thing like the following command to see what breaks for a really simple "hello world" script: sudo ../install/bin/stap -v -m hello -r 3.12.0-0.rc0.git20.1.x1.fc19.aarch64 -p4 -k -e 'probe begin {printf("hello world\n")}' The software simulator is really slow and it looks like the testsuite is probably going to time out for the tests. -Will
