Enabling Debugging Features

Enabling Debugging Features


The following macros control certain debugging features. In general, it is useful to compile with these features on for development code, and off for production code, because the features may decrease performance. The table below summarizes the macros and their default values. A value of 1 enables the corresponding feature; a value of 0 disables the feature.

Debugging Macros


Default Value



  • Windows* OS: 1 if _DEBUG is defined, 0, otherwise.

  • All other systems: 0.

Default value for all other macros in this table.



Enable internal assertion checking. Can significantly slow down performance.



Enable full support for analysis tools.


The TBB_USE_ASSERT macro controls whether error checking is enabled in the header files. Define TBB_USE_ASSERT as 1 to enable error checking.

If an error is detected, the library prints an error message on stderr and calls the standard C routine abort. To stop a program when internal error checking detects a failure, place a breakpoint on oneapi::tbb::assertion_failure.


The TBB_USE_PROFILING_TOOLS macro controls support for Intel® Inspector XE, Intel® VTune™ Amplifier XE and Intel® Advisor.

Define TBB_USE_PROFILING_TOOLS as 1 to enable full support for these tools. Leave TBB_USE_PROFILING_TOOLS undefined or equal to zero to enable top performance in release builds, at the expense of turning off some support for tools.
