Define the TBBROOT Environment Variable

With
Intel® Advisor
 samples, to build the
Intel® oneAPI Threading Building Blocks (oneTBB)
project (
_tbb
), you need to define the
TBBROOT
 environment variable.
To define this environment variable:
On Linux* OS:
  1. Open a command line window.
  2. Use the
    export
     command to set the
    TBBROOT
     environment variable, type:
    export TBBROOT=
    <tbb-install-dir>
    . If you used the default path during installation, the
    <tbb-install-dir>
     is inside:
    • For root users:
      /opt/intel/
    • For non-root users:
      $HOME/intel/
    For example, if you installed the
    Intel® oneAPI Threading Building Blocks
     as a part of Intel® oneAPI Base Toolkit, the
    <tbb-install-dir>
     may be
    /opt/intel/oneapi/tbb/<version>
    .
  3. To always set this variable on the current system, add this definition to your
    .login
     or similar shell initialization file.
On Windows* OS:
  1. Open the control panel and access:
    Control Panel
    System and Security
    System
    Advanced system settings
    Environment Variables...
    .
  2. Locate any existing definition of the
    TBBROOT
     user or system environment variable. If present, verify that it value is correct if you encountered build errors and either click
    Cancel
     or
    OK
     as needed to exit the dialog box.
  3. If it is not present, under
    System variables
     or
    User variables
    , click
    New
    .
  4. Specify the
    Variable name
     as:
    TBBROOT
    .
  5. Specify the
    Variable value
     as the path of the installed
    Intel® oneAPI Base Toolkit
     files, including the
    \tbb
     directory.
    If you installed the product as part of a
    Intel® oneAPI Base Toolkit
     and used the default path, files are installed below:
    C:\Program Files (x86)\Intel\oneAPI\
    , for example
    C:\Program Files (x86)\Intel\oneAPI\tbb\
    <version>
    .
  6. Click
    OK
     several times.
  7. For the change to take effect:
    • If using Microsoft Visual Studio*: close and reopen Visual Studio.
    • If using command window: close and reopen your command window.
    In some cases, you may need to log off and log on for this change to take effect.
  8. If needed, you can test the definition by opening a command window and typing
    set TBBROOT
    .
You have defined the
TBBROOT
 environment variable.
