OpenMP Libraries

Discusses the .lib files that make up the OpenMP run-time libraries in Visual C++.

The following libraries contain the Visual C++ OpenMP run-time library functions.

OpenMP run-time library

Characteristics

VCOMP.LIB

Multithreaded, dynamic link (import library for VCOMP.LIB).

VCOMPD.LIB

Multithreaded, dynamic link (import library for VCOMPD.LID) (debug)

If _DEBUG is defined in a compilation and if #include omp.h is in source code, VCOMPD.LIB will be the default lib. Otherwise, VCOMP.LIB will be used.

You can use /NODEFAULTLIB (Ignore Libraries) to remove the default lib and explicitly link with the lib of your choice.

The OpenMP DLLs are in the Visual C++ redistributable directory and need to be distributed with applications that use OpenMP.
