many .c source and .h header files; and b) an Intel Visual Fortran Library composed of many .f source and .inc include files. The C calls the Fortran routines, and some of the https://software.intel.com/en-us/forums/intel-visual-fortran-compiler-for-windows/topic/277002 Fortran calls the c routines. All of the Fortran successfully compiles, and the project successfully builds a '.lib'. The path to the.lib is included as an "Additional Include Directory" in the C/C++ General Project Properties pages of the C-Lib project The Project Build Order is as follows: F-Lib, C-Lib, Main (where Main Depends on the C-Lib and C-Lib depends on F-Lib). I'm encountering LNK2001 and LNK2019 unresolved external https://social.msdn.microsoft.com/Forums/vstudio/en-US/240f66fa-1ff9-4d74-883b-bfa89b124573/lnk2001-and-lnk2019-unresolved-external-symbol-link-errors-in-a-c-fortran-solution?forum=msbuild symbols related to Pointers to the Fortran commons (includes)inthe C-lib project. A snippet from a C routineflagged with aLNK2001 error: void clean_run_option_() { cleanRunOption(&run_option_common_); } 'run_option_common.inc' is one of the includes in the FLib project, that I would think should get resolved by the inclusion of the path to the.lib (Fortran)in the properties pages of the C-Lib project. Obviously something is not set right to resolve the external symbol by the Linker. Appreciate any questions, comments, guidance toward resolution.

You can refer to http://msdn.microsoft.com/en-us/library/f6xx1b1z(v=vs.100).aspx. If you can't findthecause, please show your error messages and command lines.

I investigatedthe presenceof the /Zi option in the clib project C/C++ Command Line Property Page. There is a single /Zi option present; however, it is immediately following the path the clib header files (and not, for example,the pathto the fortran ('flib') project include files; i.e., the include files the names of whichare behind the the LNK2001 unresolved

My purpose is to call the some of the functions in fortran source files from one of the C/C++ static library type project, But I am not able to build the program and am getting errors. My first attempt was to call the fortran subroutine from main.cpp. But I am getting the following error: Error 2 error LNK2019: unresolved external symbol "void __cdecl bar_ftn(int,char *)" (?bar_ftn@@YAXHPAD@Z) referenced in function _main G:\VS2010\uakron\sourcefiles\application\main.obj Error 3 error LNK1120: 1 unresolved externals G:\VS2010\uakron \build\win\debug\application_app.exe 1 source1.f90 subroutine bar_ftn ( len_input_file, input_file ) bind( c ) use, intrinsic :: iso_c_binding, only : c_int implicit none integer(c_int), value, intent(in) :: len_input_file character(len=1), intent(in) :: input_file(len_input_file) !

I am building NumPy inside the "Build Environment for Fortran IA-32 applications" with the Intel Fortran Compiler version 9.1. I am using the following command: python setup.py config --compiler=msvc --fcompiler=intelv build_clib --compiler=msvc --fcompiler=intelv build_ext --compiler=msvc --fcompiler=intelv bdist_wininst Because I am building inside this environment, the Intel compiler should be able to find all its libraries. After applying the patch in ticket #840, the !NumPy build proceeds but the get_version magic tries to link a dummy Fortran file which fails with various errors: libifcore.lib(libifcoremain.obj) : error LNK2019: unresolved external symbol _MAIN__ referenced in function _main c:\docume~1\albert\locals~1\temp\tmpwlplvf__dummy.o : fatal error LNK1120: 1 unresolved externals Later the compiler is invoked again and this fails with: LINK : fatal error LNK1104: cannot open file 'ifconsol.lib numpy-gitbot commented Oct 19, 2012 Milestone changed to 1.1 by @alberts on 2007-05-12 numpy-gitbot commented Oct 19, 2012 @pearu wrote on 2007-05-21 Could you try the recent numpy from svn? When using non MSVC libraries (such as ones provided by intel compiler) they may be in the form of libname.a but MSVC linker looks only for libraries having names in form name.lib. Recent numpy.distutils saves the copies of such libraries with the name that MSVC linker can find. numpy-gitbot commented Oct 19, 2012 @alberts wrote on 2007-05-21 Looks like it's almost there, but not quite. Firstly, a minor issue. I see stuff like this scrolling past: Fortran f77 compiler: ifl -FI -w90 -w95 /w """""""""""""""""""""""/I:C
