My comments are:
1. You can analyze a commercial application, which loads your app (built by gcc with "-g" and using TBB). It doesn't matter there is no symbol info from this commercial application, but your plug-in module will be analyzed (the tool will detect loaded module and instrument it dynamically).
2. You can filter results by selecting "Module / Function / Call stack" in "Grouping", that focus results on your interest of module.
3. Please set LD_LIBRARY_PATH correctly in console, then run amplxe-gui or amplxe-cl.
