Linking with Compiler Run-time Libraries

Dynamically link
libiomp5
or
tbb
library even if you link other libraries statically.
Linking to the
libiomp5
statically can be problematic because the more complex your operating environment or application, the more likely redundant copies of the library are included. This may result in performance issues (oversubscription of threads) and even incorrect results.
To link
libiomp5
or
tbb
dynamically, be sure the
PATH
environment variable is defined correctly.
Sometimes you may improve performance of your application with threaded
Intel® oneAPI Math Kernel Library
by using the
/MT
compiler option. The compiler driver will pass the option to the linker and the latter will load multi-thread (MT) static run-time libraries.
However, to link a Vector Mathematics (VM) application that uses the
errno
variable for error reporting, compile and link your code using the option that depends on the linking model:
  • /MT
    for linking with static
    Intel® oneAPI Math Kernel Library
    libraries
  • /MD
    for linking with dynamic
    Intel® oneAPI Math Kernel Library
    libraries
