# Windows*

This section uses <tbb_install_dir> to indicate the top-level installation directory. The following table describes the subdirectory structure for Windows*, relative to <tbb_install_dir>.

Item | Location | Environment Variable
--- | --- | ---
Header files | `<tbb_install_dir>\include\oneapi\tbb.h` `<tbb_install_dir>\include\oneapi\tbb\*.h` | `INCLUDE`
.lib files | `<tbb_install_dir>\lib\<arch>\vc<vcversion>\<lib><version><compat_version><variant>.lib` | `LIB`
.dll files | `<tbb_install_dir>\redist\<arch>\vc<vcversion>\<lib><version><compat_version><variant>.dll` | `PATH`
.pdb and .def files | Same as corresponding `.dll` file. |
CMake files | `<tbb_install_dir>\lib\cmake\tbb\*.cmake` |
pkg-config files | `<tbb_install_dir>\lib\pkgconfig\*.pc` |
vars script | `<tbb_install_dir>\env\vars.bat` |

Where

- `<arch>` - `ia32` or `intel64`

  Note

  Starting with oneTBB 2022.0, 32-bit binaries are supported only by the open-source version of the library.

- `<lib>` - `tbb`, `tbbmalloc`, `tbbmalloc_proxy` or `tbbbind`

- `<vcversion>`

  - `14` - use for dynamic linkage with the Microsoft* C runtime (CRT)

  - `14_uwp` - use for Windows 10 Universal Windows applications

  - `14_uwd` - use for Universal Windows Drivers

  - `_mt` - use for static linkage with the CRT

- `<variant>` - `_debug` or empty

- `<version>` - binary version

- `<compat_version>` - compatibility version for `tbbbind`

The last column shows, which environment variables are used by the Microsoft* Visual C++* or Intel® oneAPI DPC++/C++ Compiler, to find these subdirectories.

See Integrate oneTBB to learn how to use CMake* and pkg-config tools. To set the environment, see Next Steps.

Caution

Ensure that the relevant product directories are mentioned by the environment variables; otherwise the compiler might not find the required files.

Note

Microsoft* C/C++ run-time libraries come in static and dynamic forms. Either can be used with oneTBB. Linking to the oneTBB library is always dynamic.
