03:14 <eck> i want to register a certain probe for a list of a dozen or so functions, is there a way i can use a loop syntax to define the probes?

03:43 <eck> another qustion, can i set up a hw watch point for an address in userspace? e.g. i want to watch when process X changes the value of a particular variable

03:44 <eck> i see the docs for how to do this with kernel addresses via kernel.data but it's not clear if this can be done for a userspace process

13:12 <fche> eck, not exactly loop, but probe foo.{bar,baz,zoo} { } works e.g.

13:12 <fche> re. userspace hw watchpoint, sorry, I don't know of a way. I don't think the kernel exposes such an api, but if we can find one, it'd be great

14:17 <zamba> i have a problem compiling systemtap.. it requires C++11.. what is that? how can i ensure that my compiler supports that? i'm trying to compile this on a suse based system

14:32 <drsmith> zamba: C++11 is the 2011 ISO C++ standard. If your version of g++ supports -std=c++11, you've got C++11 support. Check the man page.

14:32 <mjw> doesn't configure make sure the right flags are added?

14:33 <drsmith> zamba: mjw is correct, configure will test your compiler and make sure it supports C++11

14:33 <zamba> drsmith: yes, and it doesn't

14:33 <zamba> configure: No compiler with C++11 support was found

14:33 <zamba> checking whether C++ compiler accepts -std=c++0x... no

14:33 <zamba> configure: error: A compiler with C++11 support is required.

14:34 <drsmith> what version of gcc do you have?

14:34 <zamba> g++ (GCC) 4.1.2 20070115 (prerelease) (SUSE Linux)

14:34 <zamba> it's OOOOLD

14:34 <zamba> because it's an old system

14:35 <drsmith> yikes - I think we at least require gcc 4.4.7

14:36 <drsmith> zamba: your best bet might be to try using an old version of systemtap where we didn't require C++11. Looks like release 3.1 was the first to require C++11.

14:37 <mjw> That gcc is only 10 years old :)
