Bug Description

libglib2.0-dev does not include GLib's systemtap probe definitions, so it is impossible to perform GLib debugging using systemtap.

Basically it means that /usr/share/systemtap/tapset/gobject.stp is missing (there is no package that provides such file).

On Fedora, it comes as part of glib*-devel.

Test case:

$ stap --ldd debugging/alive.stp -c 'src/myapp -c config.xml'
semantic error: probe point mismatch at position 0 (alternatives:
__nfs __scheduler __signal __tcpmib __vm _linuxmib _signal _sunrpc
_syscall _vfs begin begin(number) end end(number) error error(number)
generic ioblock ioblock_trace ioscheduler ioscheduler_trace ipmib
irq_handler kernel kprobe kprocess linuxmib module(string) nd_syscall
netdev never nfs nfsd perf process process(number) process(string)
procfs procfs(string) scheduler scsi signal socket softirq stap
staprun sunrpc syscall tcp tcpmib timer tty udp vfs vm workqueue):

Pass 2: analysis failed. Try again with another '--vp 01' option.

script was:

global alive
probe gobject.object_new {
 alive[type]++
}
probe gobject.object_finalize {
 alive[type]--
}
probe end {
  printf ("Alive objects: \n")
  foreach (a in alive) {
   if (alive[a] > 0)
     printf ("%d\t%s\n", alive[a], a)
  }
}
