Enable C++11 Lambda Expression Support with
Intel® oneAPI Threading Building Blocks
(
oneTBB
)

The C++11 (new standard for the C++ language, formerly C++0x) lambda expression support makes many
Intel® oneAPI Threading Building Blocks
(
oneTBB
) constructs easier to program because it avoids the need to introduce extra classes to encapsulate code as functions. If you decide to use this feature, you need a compiler that supports it, such as the
Intel® C++ Compiler Classic
or
Intel® oneAPI
DPC++/C++
Compiler
. For more information about C++11 lambda expression support in the other compilers, please see your compiler documentation (online help).
When using the command line with the
Intel® C++ Compiler Classic
or
Intel® oneAPI
DPC++/C++
Compiler
, specify the following option to enable lambda expression support:
  • For Windows* OS:
    /Qstd=c++0x
  • For Linux* OS:
    -std=c++0x
To enable the C++11 support in Visual Studio on a Windows* OS system:
  1. In Solution Explorer, select (click) the name of one or more projects. To select multiple projects, hold down the
    Ctrl
    key.
  2. Right-click the project name and select
    Intel Compiler
    >
    Use Intel C++
    from the context menu.
  3. Select
    Project
    >
    Properties
    , or right-click the project name and select
    Properties
    from the context menu.
  4. Specify the following Configuration Properties:
    C++
    >
    Language
     Under
    Intel Specific
    , select
    Enable C++0x Support
    as
    Yes
  5. Click
    OK
    to save the specified properties.
  6. Repeat the steps above for other configurations.
You have set up your environment to use the C++11 lambda expression support.
