Troubleshooting report issues

If you successfully complete a capture session but have a problem with the resulting report data, consult this list of common issues.

Each common problem is listed with a possible solution:



Streamline does not show any source code in the Code view.

Make sure that you use the -g option during compilation. Streamline must have debug symbols turned on to match instructions to source code.

Streamline does not show source code for shared libraries.

Add the libraries using the Capture & Analysis Options dialog box. Click Add ELF Image... in the Program Images section, navigate to your shared library, and then add it.

The data in the Call Paths view is flat. The presented table is a list rather than a hierarchy.

Use the -fno-omit-frame-pointer and -marm options during compilation and check the Call Stack Unwinding option in the Capture & Analysis Options dialog box.


Streamline does not walk the stack for kernels, loadable kernel modules, or statically linked drivers. These generate flat data in the call paths view.

Functions that you know are highly used are missing from the reports. Other functions might seem artificially large.

This can be because of code inlining done by the compiler. To turn inlining off, add -fno-inline as an option during compilation.

A newly-generated capture has no data.

If you experience this and the profiling session had event-based sampling enabled, the PMU on your target might not have triggered the interrupts correctly. Test on alternate hardware or disable event-based sampling in the Counter configuration dialog box.
