Solved Failed to run dtrace scripts

Hi,

I just encounter some errors when I try to run the Dtrace scripts under /usr/share/dtrace/toolkit, but am not sure how to handle them:

Code: 
root@darkgeek.pts/1 dtrace/toolkit # ./procsystime -n csh
dtrace: invalid probe specifier
#pragma D option quiet

/*
* Command line arguments
*/
inline int OPT_elapsed = 1;
inline int OPT_cpu = 0;

...<skip>...

: "/usr/lib/dtrace/ip.d", line 111: failed to copy typedef in6_addr_t
source type: Type information is in parent and unavailable

root@darkgeek.pts/1 dtrace/toolkit # perl ./hotkernel
Sampling... Hit Ctrl-C to end.
dtrace: invalid probe specifier
#pragma D option quiet
profile:::profile-1001hz
/arg0/
{
@pc[arg0] = count();
}
dtrace:::END
{
printa("%a %@d\n", @pc);
}
: "/usr/lib/dtrace/ip.d", line 111: failed to copy typedef in6_addr_t
source type: Type information is in parent and unavailable

FUNCTION COUNT PCNT

Seems they both complain an error of "Type information is in parent and unavailable".

My computer has FreeBSD 10.1-RELEASE (GENERIC kernel) amd64 installed, and the following is a list of loaded modules:

So what should I do to solve it? Thanks:D.
 
I had seen some odd failures like that running amd64 on a Soekris with the i386 CPU. Everything else on the system ran fine except dtrace(1).

What does dmesg | head -20 say as far as CPU type/features? Are you compiling your own system or are you using an install from an official ISO?

As to this system, I upgraded it from source (using GENERIC configuration) from 10.0 to 10.1 RELEASE.

According to https://wiki.freebsd.org/DTrace/KernelSupport, that is saying something is not correct with how DTrace was compiled in. That shouldn't be an issue with the default 10.1 configuration. A basic sanity check may be to boot from an ISO and immediately drop to a shell and attempt to run the DTrace command.

Hi,

I compile the kernel using GENERIC configuration again and dtrace works like a charm! So the issue stated before maybe is due to my broken upgrading process.
