I have a code which is compiled in Visual Studio Enterprise 2017 v15.8.9 using Intel Parallel Studio XE 2017 Update 4 Composer Edition for Fortran. This works perfectly fine.
On a different computer, I have recently installed Visual Studio 2019 and Intel Parallel Studio XE 2020 Composer Edition for Fortran. With the exact same code, I get the following error when trying to access the DLL:
Entry Point Not Found
The procedure entry point pow2o3 could not be located in the dynamic link library C:\path...
I installed Visual Studio 2017 and Intel Parallel Studio XE 2017 Update 8 Composer Edition for Fortran on the other computer and then it worked. Is there a bug in the new compiler?
I would first compare the output of the buildlogs to see what options are different. A dumpbin of the dll's to see what entry points are defined might also tell you something.
I got a similar error when I compiled my program with VS 2019 and Parallel Studio 2019. I found that the problem was because another program that I had installed had place the Intel Fortran runtime libraries in my C:\Windows\System32 directory. These libraries were from a previous version of Intel Fortran. Fortunately I no longer needed the other program and I uninstalled it which removed these libraries. Then my program compiled from VS2019 started working without this kind of error. The error I was getting referred to the 'pow2o3f' entry point. I believe both of these are in the math library libmmd.dll
