Unable to compile Timer sample (timertest.c, timerperformance.c)

300 Views

"This example provides functionality to test performance of the VT_timestamp() function."

"Ensure that the corresponding compiler, Intel MPI Library, and Intel Trace Analyzer and Collector are already in your PATH"

When trying to build (make) the example, all I can get is the following error message:

"You need to set VT_ROOT env variable to use Intel(R) Trace Collector"

What should I do to set up the proper environment to compile only this utility ?

The utility is attached to this message as a ZIP file.

Thanks.
