Hi, I am pretty new to Intel C++ compiler and am appreciated for your help.
I want to confirm which of the following is true during compile link process:
1. static openMP libiomp5mt.dll is not supported for Win 10
2. static openMP libiomp5mt.dll is not supported for Parallel Studio 2020 XE Intel Compiler 19.1
3 static openMP libiomp5mt.dll is supported for Parallel Studio 2020 XE on Win 10, I missed something so I don't have it.
Background info: When I compile on my Win 7 machine with Parallel Studio 2019, I always link to the static libiomp5mt.dll. I want to test whether compile works on win 10 machine, I install a trial version of Parallel Studio 2020 with Intel Compiler 19.1. I don't see static libiomp5mt.dll anymore in my C drive, instead I have to link to dynamic library libiomp5md.dll.
Is there any document can confirm that libiomp5mt.dll is not supported? Or it is still supported but I missed something.
I find libiomp5mt.dll is not supported for Intel Fortran compiler 19.0 in this release note:
I don't see it anywhere in the Intel C++ compiler release note. Thanks.
I found here that the static library is not supported for Intel Compiler 19.1 on Windows:
My next question is, which old version of Intel compiler still support the static library for Windows? Thanks.
I am not sure why you see libiomp5dt.dll with Parallel Studio 2019.

We do not support a static version of the OpenMP library on Windows. We removed that around version 13.0. The Windows environment favors dynamic linking - it is easier to apply security patches by dropping new DLL files. There has been ongoing arguments for years between static and dynamic linking. For Windows, the community favors dynamic linkage. This is why we freely distribute our runtime libraries in a kit you can distribute to remote users of your programs - they can easily install this runtime which gives them all our Intel library DLLS. OR you can simply drop them along side your .exe file.
to find out what DLLs are needed by your .exe you can use a tool like "Depends" to find all the DLL dependencies of any .exe file.
