Unresolved Externals in RELEASE but not DEBUG version

Jump to solution

Hello,

I can successfully compile/link/execute a Visual Fortran (XE 12.0.3.175 [IA-32]) DEBUG version of an application using the MKL under MS Visual Studio 2008. However, when attempting to build a RELEASE version of the application, link errors pertaining to the MKL occur. For example:

[bash]error LNK2019: unresolved external symbol _SGETRF@24 referenced in ...[/bash]
I have repeatedly checked to ensure the properties settings

[bash]Project > Properties > Configuration Properties > Linker > General > Additional Library Directories
Project > Properties > Configuration Properties > Linker > Input > Additional Dependencies.[/bash]
are identical for both DEBUG and RELEASE as per the Help information in

[bash]Configuring Intel Visual Fortran to Link with Intel MKL
[/bash]
I would appreciate guidance on how to locate/fix my mistakes.

Thanks,

-- jv

If a routine that calls MKL was compiled with /iface:CVF, you must use mkl_intel_s.lib rather than mkl_intel_c.lib to link your application. See if that is enough to build the application.

If you mix objects compiled with /iface:cvf and those compiled without that option, you have to be extra careful since /iface:cvf does not give you fine enough control. You may need to use !DEC$ directives.

The unsatisfied external name, _SGETRF@24, indicates that the STDCALL convention was in effect when the routine containing the call to SGETRF was compiled. This convention is not the default for Intel Fortran and was chosen either by specifying the option in your project settings or as a command-line option, or using directives in your sources.

Please check your project settings, clean and rebuild. If you still get the same message, attach the build-log to your reply.

Thanks for the helpful feedback. I now have a better understanding of the error.

My intention is to use the CVF call interface because of a dependency on an external library.

I am a novice user of the Visual Studio tool so I probably have made a mistake in its use regarding RELEASE and DEBUG builds. So far, I can not find the mistake.

As suggested, I have repeatedly performed a clean operation prior to a rebuild; the link error persists.

I have included the logs from the two stages of the RELEASE build; in Visual Studio parlance the Solution comprises a Library Project and an executable Project that uses the library. Note, this library is not the external dependency mentioned in the first paragraph above. Also note, the MKL dependencies are in my project library (not in the external dependency library).

Here is the build log for the library project:

Wow ! Thanks ! I really appreciate your quick response and willingness to wade through the build logs.

Using mk_intel_s.lib (in place of mkl_intel_c.lib) resulted in successful compilation, linking, and execution.

I don't know if I would have ever resolved this.

It was (un)fortunate the DEBUG version worked with mkl_intel_c.lib.
