Intel® Fortran Compiler 16.0 User and Reference Guide
Lets you specify an OpenMP* run-time library to use for linking. Option -qopenmp-lib is the replacement option for -openmp-lib, which is deprecated.
Linux and OS X: | -qopenmp-lib=type |
Windows: | /Qopenmp-lib:type |
type |
Specifies the type of library to use; it implies compatibility levels. Currently, the only possible value is:
|
-qopenmp-lib=compat |
The compiler uses the compatibility OpenMP* run-time library (libiomp). |
This option lets you specify an OpenMP* run-time library to use for linking.
The compatibility OpenMP run-time libraries are compatible with object files created using the Microsoft* OpenMP run-time library (vcomp) or the GNU OpenMP run-time library (libgomp).
To use the compatibility OpenMP run-time 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* OS: -qopenmp or -qopenmp-stubs
Windows* OS: /Qopenmp or /Qopenmp-stubs
On Windows* systems, the compatibility OpenMP* run-time 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 run-time library.
On Linux* systems, the compatibility Intel OpenMP* run-time 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 compilers. The linking phase results in a single, coherent copy of the run-time library.
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 run-time libraries are incompatible.
The compatibility OpenMP run-time library is not compatible with object files created using versions of the Intel compilers earlier than 10.0.
On Windows* OS, this option is processed by the compiler, which adds directives to the compiled object file that are processed by the linker. On Linux* OS and OS X*, this option is processed by the ifort command that initiates linking, adding library names explicitly to the link command.
