Feature Macros

Macros in this section control optional features in the library.


The macros starting with TBB_DEPRECATED control deprecated features that would otherwise conflict with non-deprecated use. Define it to be 1 to keep using an earlier version of API or behavior.


The macro TBB_USE_EXCEPTIONS controls whether the library headers use exception-handling constructs such as try, catch, and throw. The headers do not use these constructs when TBB_USE_EXCEPTIONS=0.

For the Microsoft Windows*, Linux*, and macOS* operating systems, the default value is 1 if exception handling constructs are enabled in the compiler, and 0 otherwise.


The runtime library may still throw an exception when TBB_USE_EXCEPTIONS=0.

C++11 Support

To enable functionality that requires C++11, you need to use a compiler that supports C++11 mode, and compile your code with this mode set. C++11 support is off by default in the compiler.

In some cases TBB headers cannot correctly detect availability of necessary C++11 features in a C++ standard library. For example, when GNU libstdc++ library is used with a compiler that does not set GCC version macros (__GNUC__ etc.) or, like Clang, sets them to a version that does not match the version of libstdc++.

The macro TBB_USE_GLIBCXX_VERSION can be used to specify the proper version of GNU libstdc++ if the detection fails. Define the value of the macro equal to Major*10000 + Minor*100 + Patch, where Major.Minor.Patch is the actual GCC/libstdc++ version (if unknown, it can be obtained with 'gcc -dumpversion' command). For example, if you use libstdc++ from GCC 4.9.2, define TBB_USE_GLIBCXX_VERSION=40902.
