Search Directories

Search directories are used to locate supporting files and display analysis information in relation to your source code.

In some cases, the Intel® VTune™ Amplifier cannot locate the supporting user files necessary for displaying analysis information and you may need to configure additional search locations or override standard ones. This is required for .exe projects on Windows* created out of Microsoft Visual Studio*, where no information about project directory structure is available, for C++ projects with a third party library for which you wish to define binaries/sources, or for the imported projects with the data collected remotely. When you run a remote data collection, the VTune Amplifier copies binary files from the target system to the host by default. You need to either copy symbol and source files to the host or mount a directory with these files.

VTune Amplifier searches the directories in the particular order when finalizing the collected data. For the VTune Amplifier integrated into the Visual Studio IDE, the search directories are defined by the Microsoft Visual Studio C++ project properties.

For successful module resolution, the VTune Amplifier needs to locate the following files:

  • binaries (executables and dynamic libraries)

  • symbols

  • source files

It automatically locates the files for C/C++ projects that are not moved after building the application and collecting the performance data.

Configure Search Directories

To configure search directories:

  1. Click the Configure Analysis toolbar button.

    The Configure Analysis window opens.

  2. Click the Search Sources/Binaries button at the bottom to open the corresponding dialog box and specify paths for symbol, binary and source files for the file resolution on the host.

  3. To add a new search directory in the Search Directories table, click the <Add a new search location> row and type in the path and name of the directory in the activated text box, or click the browse button on the right to select a directory from the list. For example, if your project was initially located in /work/projects/my_project on Linux* and then was moved to /home/user/my_project_copy, you need to specify the /home/user/my_project_copy as a search directory for binary/symbol and source files.


The search is non-recursive. Make sure to specify all required directories.

If the search directories were not configured properly and modules were not resolved, you may see the following:

  • In the Summary window, you see a pop-up message starting with "Data is not complete due to missing symbol information for user modules...". This pop-up window provides shortcut options to specify search directories and re-resolve the analysis result.

  • In the Bottom-up or Top-down Tree pane, the module shows only one [Unknown] line instead of meaningful lines with function names.

  • When you double-click a row to view the related source code, you get a Cannot find the source file window asking you to locate the source file.

If the VTune Amplifier cannot locate symbol files for system modules, it may provide incomplete stack information in the Bottom-up/Top-down Tree panes and Call Stack pane. In this case, you may see [Unknown frame(s)] hotspots when attributing system layers to user code using the Call Stack Mode option on the filter toolbar. To avoid this for Windows targets, make sure to configure the Microsoft symbol server or set the _NT_SYMBOL_PATH environment variable. For Linux targets, enable Linux kernel analysis.
