Jay I'm concerned you couldn't open a case. Can you please try again, and note that alphabetically, the product is not under "V" for VTune, but "B" for Beta.
What do you think?
cheers

So there is a bit of hope still...
I'm usingVTServer from VTune Analyzer7.1 Beta.
I guess you're implying Thread View should work with standalone Analyzer 2.0 for Linux. Is that right?
Thanks

Hello Henric,
You've hit the nail on the head already: the tarball you downloadedvt_cli_2.0.348.tar is not beta, it's final product. Beta licenses don't work with final product.

I'm trying to use the sampling feature of vtune to profile my application built with icc but I keep getting "no symbols were found" when I try to view the hotspot function results for a shared object (.so) module.
I've boiled this down to a simple test case which works fine with gcc but not with icc.
$ cat foo.h
#ifndef FOO_H
#define FOO_H
void foo ();
#endif
(please substitute "less-than" for appropriate symbol, the forum things I'm trying to post html when I have an angle bracket)
$ cat foo.c
#include "foo.h"
void foo () {
int i;
for( i = 0; i less-than 100000000; i++) {
}
}
$ cat main.c
#include "foo.h"
int main () {
int i;
for( i = 0; i less-than 5; i++) {
foo();
}
}
$ icc -g -shared -fPIC foo.c -o libfoo.so
$ icc -g -c main.c -o main.o
$ icc main.o -lfoo -L.
$ vtl activity -c sampling -app a.out run
[ vtune runs ]
$ vtl show -hf -mn libfoo.so
[ .. event information .. ]
No symbols were found
If I compile *exactly* the same way using gcc instead of icc I will get the desired results (i.e. I get event %'s about my functions). I've also tried compiling with gcc using the -gdwarf-2 flag in place of the -g flag which also gives the desired results.
Why does this not work with the intel compiler? Is VTune not capable of profiling an application built this way? Does anybody have any ideas what could be wrong?
Thank You,
Nathan
some info:
icc: Version 8.0
gcc: Version 2.96
OS : RedHat 7.3 [kernel 2.4.18-3] (also tried on RHAS2.1)

Hey Nathan,
VERY interesting problem description.
But before we dig in too far, which version of vtune are you using?
$ vtl version

However, it requires a patch to kernel 2.6.0-test5 (i.e., users must rebuild that kernel with the patch, and we include the patch along with the VDK sources).
We have not tested/ported VDK driver to any version of kernel 2.6.x (patched or otherwise) on Itanium Linux as yet.
I hope this helps.cheers
