unresolved external symbol for_dealloc_allocatable_handle referenced in function

I am migrating from Intel FORTRAN 2018 to the current version and am getting a bunch of unresolved externals relating to allocatable variables.  It is pretty generic FORTRAN and has been through many compilers without issue until now.

 

>Model003_lib.lib(solver.obj) : error LNK2019: unresolved external symbol for_dealloc_allocatable_handle referenced in function SOLVE
1>Model003_lib.lib(solver.obj) : error LNK2019: unresolved external symbol for_alloc_allocatable_handle referenced in function SOLVE

 

Am I missing a library or something?  Using Visual Studio 2022 and 2026 with FORTRAN integrated into it.

 

Any help would be greatly appreciated.

 

Thanks.

An error of this nature usually indicates that you are linking to language libraries older than the compiler.
