Hi, I'm having problems with the helloworld.stp tap: semantic error: probe point mismatch at position 0 (alternatives...) identifier 'oneshot' at helloworld.stp:2:7 while resolving probe point oneshot
<DuncanT>
Is this anything well known?
<fche>
DuncanT, how old is your stap version?
<fche>
probe oneshot was added (as an alias of 'begin' and some other stuff) quite some time ago
<DuncanT>
$ stap --version
<DuncanT>
Systemtap translator/driver (version 1.7/0.159 Debian version 1.7-1+deb7u1 (stable))
<fche>
bet the copyright date gives you an idea

Fairly old then
<DuncanT>
I'll see if I can build something newer

yeah. 'probe oneshot' was in release 2.5, now itself almost two years old
<DuncanT>
Is there a helloworld for older versions at all please?
<fche>
DuncanT, anyway, if you're stuck with that old version, then you just need to avoid using newer features; things should still mroe or less work
<fche>
of course:
<fche>
stap -e 'probe begin { log("hello world") exit() }'

chances are a library of sample scripts are included with your copy of stap someplace (/usr/doc/systemtap or something like that)
