qopenmp-lib, Qopenmp-lib
Lets you specify an OpenMP* runtime library to use for linking. This feature is only available for ifort.
Syntax
Linux: |
-qopenmp-lib=type |
macOS: |
-qopenmp-lib=type |
Windows: |
/Qopenmp-lib:type |
Arguments
type |
Specifies the type of library to use; it implies compatibility levels. Currently, the only possible value is:
|
Default
-qopenmp-lib=compat |
The compiler uses the compatibility OpenMP* runtime library (libiomp). |
Description
This option lets you specify an OpenMP* runtime library to use for linking.
The compatibility OpenMP runtime libraries are compatible with object files created using the Microsoft* OpenMP runtime library (vcomp) or the GNU OpenMP runtime library (libgomp).
To use the compatibility OpenMP runtime library, compile and link your application using the compat setting for option [q or Q]openmp-lib. To use this option, you must also specify one of the following compiler options:
Linux* systems: -qopenmp or -qopenmp-stubs
Windows* systems: /Qopenmp or /Qopenmp-stubs
Linux
The compatibility Intel OpenMP* runtime library lets you combine OpenMP* object files compiled with the GNU* gcc or gfortran compilers with similar OpenMP* object files compiled with the Intel® C, Intel® C++, or Intel® Fortran Compiler. The linking phase results in a single, coherent copy of the runtime library.
This option is processed by the compiler driver command that initiates linking, adding library names explicitly to the link command.
You cannot link object files generated by the Intel® Fortran compiler to object files compiled by the GNU Fortran compiler, regardless of the presence or absence of the [Q]openmp compiler option. This is because the Fortran runtime libraries are incompatible.
Windows
The compatibility OpenMP* runtime library lets you combine OpenMP* object files compiled with the Microsoft* C/C++ compiler with OpenMP* object files compiled with the Intel® C, Intel® C++, or Intel® Fortran compilers. The linking phase results in a single, coherent copy of the runtime library.
This option is processed by the compiler, which adds directives to the compiled object file that are processed by the linker.
