How to link Fortran library containing a class using ifort

Question

I am trying to identify why I am receiving an error when linking a static library which has a class containing type-bound procedures.

When I compile and link on the command-line:

This works (and the resulting executable runs properly)

ifort src/main.F90 C:\Temp\lib\test.lib /include:"C:\Temp\mod" $(Opts) /link $(Lnk)

but This does NOT work

ifort src/main.F90 /include:"C:\Temp\mod" $(Opts) /link /LIBPATH:"C:\Temp\lib\test.lib" $(Lnk)

I'd appreciate any suggestions on why the latter command does not work. It is the commandline format by which I link typical libraries. The link errors below from the latter command refer to the type-bound procedures of the Fortran class definition that is contained in test.lib.

(note that ifort and linker versions are contained below. The platform is Windows 7 and I am using make via MinGW in both of the above cases)

ifort src/main.F90  /include:"C:\Temp\mod" /fpe:0 /real_size:64 /integer_size:64 /names:lowercase /iface:cref /iface:mixed_str_len_arg /assume:byterecl /extend_source:132 /O3 /traceback  /INCREMENTAL:NO /link /LIBPATH:"C:\Temp\lib\test.lib" /STACK:100000000 /MAP /MANIFEST /NODEFAULTLIB:msvcrt.lib

Answer 1

The /LIBPATH linker option specifies a directory in which to search for libraries. The second command appears to be using it to specify the library file itself.

Either delete the /LIBPATH: option prefix from the command line, or split the library name from the directory search specification - /LIBPATH:"C:\Temp\lib" ..... test.lib.
