It uses an imports library, such as libiomp5.lib, instead.<BR /><BR />If you do not have an equivalent static library, you are stuck with having to use the DLL at run time.

The option /Qopenmp-link:static has been provided in some versions of ifort, or you can link libiomp5mt.lib explicitly, if you take care not to link more than once against any of the libiomp, libguide, or vcomp versions.

Is this something I can accomplish with a use or include statement in my code, even if IMSL is calling this library? I think I understand how to specify additional library directories, but not how to explicitly link a particular file.

If so, change the file name to libiomp5mt.lib Wed, 15 Jun 2011 20:27:10 GMT https://community.intel.com/t5/Intel-Fortran-Compiler/compile-using-libiomp5md-lib-rather-than-libiomp5md-dll/m-p/804943#M39737 Steven_L_Intel1 2011-06-15T20:27:10Z https://community.intel.com/t5/Intel-Fortran-Compiler/compile-using-libiomp5md-lib-rather-than-libiomp5md-dll/m-p/804944#M39738 Making the change in this line seems to have worked. Thank you.
