"unresolved external symbol" issue when building NetCDF with Intel Foxtran OneAPI

Hi all,

In the past, we can integrate Netcdf with Intel Parallel Studio in our foxtran project successfully. I have been trying to integrate NetCDF with the latest OneAPI using Visual Studio 2019. I set the "additional including directories" in the Foxtran section to the folder "NetCDFLib\x64\include" and set the "Additional library Directory" to the folder NetCDFLib\x64\lib properly (Please see the attached files for more details).

I see the following errors after building the project

------ Build started: Project: EFDCPlus_MPI_10.3.0, Configuration: 64SP_D_MPI x64 ------

Do I need to rebuild Netcdf dll and lib using OneAPI C++ compiler? Please help me to resolve this issue as soon as possible. Thanks  in advance.

It's not helpful to show a screenshot of a property window where the contents are truncated.

The missing references are to the object file created when Fortran module NETCDF was compiled. I can't tell from your attachments exactly how you should go about fixing that.

I just attached full screenshots of property windows.  Please give me an idea how to fix this issue. It works well when I used the intel parallel studio in the past. Thanks.

You didn't show the linker property page. If you could attach a zip of the .vfproj file that might help. As I wrote earlier, the unresolved references are to the .obj created when Fortran module NETCDF was compiled.

I did see you have set the calling convention to "C, REFERENCE".  This is a bad idea, though isn't the cause of this particular issue as far as I can tell.

I just attached the linker property page.   I tried all options of calling convention ("C, REFERENCE", "STDCALL REFERENCE", "STDCALL", "CVF") and nothing works. You can see the vfproj file as belows:

I did say that the calling convention property was not relevant - it was simply something I thought you should not use.

Another option you should not use is "Ignore default libraries". 

As I have written more than once, the unresolved references would be supplied in the object file from a Fortran module called NETCDF. Your task is to find out where that is supposed to be supplied from. At this point you're just throwing things against the wall.  I assume that somewhere in your program is a "USE NETCDF". This will look for a netcdf.mod file, probably in some Include folder such as \NetCDFLib\x64\include . The question I can't answer for you is - where is the .obj file that goes with netcdf.mod? It apparently is not inserted into any of the libraries you link against. If you find it, add it to the "source files" for the project.
