Error linking Intel OneAPI and ANSYS

[YaxiongChen]

ANSYS manual recommends to use the following compiler: Microsoft visual studio Professional 2017, Intel C++ 2019.3.203 and FORTRAN 2019.3.203. However, I could not  find the download for C++ and FORTRAN compiler. 

Some post suggests to use Intel OneAPI instead. So I install OneAPI , and run  IntelAPI tools with administrative privilege. Then I made a small change in ANSCUST.BAT, replacing compilervars.bat with setvars.bat. But I got the following error.

Few of us in this forum use or have access to ANSYS. You only show us the error message, but not the link step command line. What I can tell is from the error message is that the compilation succeeded and produced an OBJ file, but the next step failed -- the step of linking the OBJ and appropriate libraries in order to generate a DLL. Post the contents of the batch file that you used, or at least the link command line.

It is possible that the version of ANSYS that you have cannot work with the OneAPI compiler and libraries, because some of the library routine names may have been changed.

I am running a following batch file. Can you find something from it?  Can @Steve_Lionel help with it? Thanks

your scripts has:
"VCINPATH=%VS2017INSTALLDIR%\VC\Tools\MSVC\14.10.25017"

So it seems you want the VC TOOLS path. I do not know if that is correct for your system but I would suggest:
"VCINPATH=%VCToolsInstallDir%

As that is what the setvars from OneAPI sets on my system that is
VCToolsInstallDir=C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\

That batch file is rather long, and probably impossible to debug without having ANSYS installed. As far  as I can see, the link command is 

     link @ansys.lrf 2>&1 | findstr /V /R /c:"^ansyslib..lib.* LNK4099: PDB" /c:"^zlibwapi.lib.* LNK4099: PDB"

For this to work, the earlier commands in the batch file should have placed a list of names of OBJ (and, possibly, LIB) files into the file ansys.lrf. You can see if you have that file, and list the file. If the expected usermat.OBJ is not present, you could investigate the causes. If the file is present and looks proper, you could try the command

     link @ansys.lrf 

and this command would let you see any error messages from the linker, which the redirection 2>&1 may have hidden.

These matters are more appropriate for discussion in a forum for ANSYS users.

Have you found a solution, please?
