The solution is to expilcitly call out either a dynamic or static link. To link the dynamic OpenMP runtime library specify the options /MD and /Qopenmp-link=dynamic. To link statically specify /MT and /Qopenmp-link=static.

The caution about not linking more than one of the OpenMP libraries still applies. If you link both libguide and vcomp instead of libiomp5 alone, you are on shaky ground, as you are if you make a .dll with static OpenMP included and then link elsewhere with dynamic OpenMP, for example. As you don't have command line options to choose the libiomp5 or static or dynamic, you will have to rely on explicit command line or project library dependencies.<BR /> Tue, 03 Mar 2009 17:04:02 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/OMP-Error-15-Initializing-libguide-lib/m-p/889076#M10247 TimP 2009-03-03T17:04:02Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/OMP-Error-15-Initializing-libguide-lib/m-p/889077#M10248 <DIV style="margin:0px;">As an additional comments to your questions, please look at the article OMP Abort: Initializing libguide40.dll but found libiomp5md.dll already initialized following the link <A href="http://software.intel.com/en-us/articles/opm-abort-initializing-libguide40dll" target="_blank">http://software.intel.com/en-us/articles/opm-abort-initializing-libguide40dll</A> <BR />--Gennady</DIV> <BR /> Tue, 03 Mar 2009 18:13:10 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/OMP-Error-15-Initializing-libguide-lib/m-p/889077#M10248 Gennady_F_Intel 2009-03-03T18:13:10Z
