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.
