Notes:

  1. Applications can be run on the same Windows versions as specified above for development. Applications may also run on non-embedded 32-bit versions of Microsoft Windows earlier than Windows 10, though Intel does not test these for compatibility.  Your application may depend on a Windows API routine not present in older versions of Windows.  You are responsible for testing application compatibility. You may need to copy certain run-time DLLs onto the target system to run your application.
  2. The default for Intel® Fortran Compiler for Windows* is to build IA-32 architecture applications that require a processor supporting the Intel® SSE2 instructions.  A compiler option is available to generate code that will run on any IA-32 architecture processor. Note, however, that applications calling Intel® MKL require a processor supporting the Intel® SSE2 instructions.
  3. To use the Intel® Fortran Compiler for Windows* with Microsoft Visual Studio 2017*, it is necessary to install the 'Desktop development with C++' component from Visual Studio.  This article explains how.

Compatibility

In general, object code and modules compiled with earlier versions of Intel Fortran Compiler (8.0 and later) may be used in a build with version 19.1. Exceptions include:

  • Sources that use the CLASS keyword to declare polymorphic variables and which were built with a compiler version earlier than 12.0 must be recompiled.
  • Objects built with the multi-file interprocedural optimization (/Qipo) option must be recompiled.
  • Objects that use the REAL(16) , REAL*16, COMPLEX(16) or COMPLEX*32 datatypes and which were compiled with versions earlier than 12.0 must be recompiled.
  • Objects built for the Intel® 64 architecture with a compiler version earlier than 10.0 and that have module variables must be recompiled.  If non-Fortran sources reference these variables, the external names may need to be changed to remove an incorrect leading underscore.
  • Modules that specified an ATTRIBUTES ALIGN directive outside of a derived type declaration and were compiled with versions earlier than 11.0 must be recompiled.  The compiler will notify you if this issue is encountered.
  • Modules that specified an ATTRIBUTES ALIGN directive inside a derived type declaration cannot be used by compilers older than 13.0.1.
  • The implementation of the Fortran 2008 submodules feature required extensive changes to the internal format of binary .mod files. Therefore module files created by the version 16.0 Fortran compiler cannot be used with version 15.0 or older Fortran compilers.
  • Objects built with Intel Fortran Compiler version 18.0 and earlier version of regcall calling convention must be recompiled with 19.0 or newer. Intel library libirng uses regcall. Version of this library shipped with 19.0 compiler version or newer is not compatible with older versions. regcall is implicitly used by following attribute:
    !DIR$ ATTRIBUTES [att,] VECTOR [:clause] [, att]... :: routine-name

Stack Alignment Change for REAL(16) and COMPLEX(16) Datatypes (12.0)

In previous releases, when a REAL(16) or COMPLEX(16) (REAL*16 or COMPLEX*32) item was passed by value, the stack address was aligned at 4 bytes.  For improved performance, compiler versions 12.0 and later align such items at 16 bytes and expect received arguments to be aligned on 16-byte boundaries.

This change primarily affects compiler-generated calls to library routines that do computations on REAL(16) values, including intrinsics. If you have code compiled with earlier versions and link it with the version 13 libraries, or have an application linked to the shared version of the Intel run-time libraries, it may give incorrect results.

In order to avoid errors, you must recompile all Fortran sources that use the REAL(16) and COMPLEX(16) datatypes.

Static Form of the Intel® OpenMP* Library is No Longer Provided

The static form of the Intel® OpenMP* library, libiomp5mt.lib, is no longer provided, and the /Qopenmp-link:static command line option is no longer supported. Please replace all references to libiomp5mt.lib with libiomp5md.lib, the DLL import library.  This change also implies that applications using OpenMP will need to have the Intel® compiler redistributables installed if deployed on a system where an Intel® compiler is not also present. See Redistributable Libraries for Intel® Parallel Studio XE for more information.

Fortran Expression Evaluator

Fortran Expression Evaluator (FEE) is a plug-in for Microsoft Visual Studio* that is installed with Intel® Fortran Compiler. It extends the standard debugger in Microsoft Visual Studio* IDE by handling Fortran expressions. There is no other change in usability.

  • The arguments to the SIGN function may be of different kinds
  • INTEGER and LOGICAL arguments to intrinsic procedures are no longer required to be of default kind
  • The named constants STAT_FAILED_IMAGE and STAT_UNLOCKED_FAILED_IMAGE have been defined in the intrinsic 
    ISO_FORTRAN_ENV module
  • The non-block DO statement and the arithmetic IF statement are now deleted in Fortran 2018.  Intel® Fortran fully supports features deleted in the FORTRAN standard
  • COMMON, EQUIVALENCE and BLOCKDATA statements are now obsolescent
  • The labeled form of DO loops is now obsolescent
  • Locality of variables in DO CONCURRENT constructs can now be declared on the DO CONCURRENT statement
  • Specific names of intrinsic procedures are now obsolescent
  • FAIL IMAGE statement allows debugging recovery code for failed images without having to wait for an actual image failure
  • The named constants STAT_FAILED_IMAGE and STAT_UNLOCKED_FAILED_IMAGE have been defined in the intrinsic 
    ISO_FORTRAN_ENV module
  • An optional argument STAT= has been added to ATOMIC_REF and ATOMIC_DEFINE intrinsic procedures
  • Optional STAT= and ERRMSG= specifiers have been added to the MOVE_ALLOC intrinsic procedure, to image selectors, and to the CRITICAL statement and construct

  • The SELECT RANK construct has been implemented allowing manipulation of assumed rank dummy arguments
  • The compiler will now diagnose the use of nonstandard intrinsic procedures and modules as required by Fortran 2018
  • Transformational intrinsic functions from the intrinsic modules ISO_C_BINDING, IEEE_ARITHMETIC, and IEEE_EXCEPTIONS are now allowed in specification expressions
  • You can now specify the optional argument RADIX for the IEEE_GET_ROUNDING_MODE and IEEE_SET_ROUNDING_MODE intrinsic module procedures
  • The optional ROUND argument has been added to the IEEE_RINT function in the intrinsic module IEEE_ARITHMETIC
  • The intrinsic module IEEE_ARITHMETIC now includes the functions IEEE_FMA, IEEE_SIGN_BIT, IEEE_NEXT_UP and IEEE_NEXT_DOWN
  • The intrinsic module procedures IEEE_MAX, IEEE_MIN, IEEE_MAX_MAG, and IEEE_MIN_MAG have been implemented
  • The intrinsic module procedures IEEE_INT and IEEE_REAL have been implemented
  • The intrinsic module IEEE_EXCEPTIONS now contains a new derived type, IEEE_MODES_TYPE, which can be used to save and restore the IEEE_MODES using the IEEE_GET_MODES and the IEEE_SET_MODES intrinsic module procedures
  • A new rounding mode, IEEE_AWAY has been added
  • SUBNORMAL is now synonymous with DENORMAL

New features from OpenMP 5.0*

  • IF clause on SIMD directive
  • NONTEMPORAL clause on SIMD directive
  • Inclusive/exclusive scan operations in SIMD and TARGET SIMD constructs.

Changed compiler behavior

  • Previous compiler versions erroneously permitted a PRIVATE or SEQUENCE statement to appear prior to the declaration of any type parameters in a derived type declaration.  Intel® Fortran Compiler 19.1 no longer permits this behavior.
  • The INQUIRE statement now uses the realpath() function with argument ’/’’GetFullPathNameA’ and uses the resulting canonicallized file-paths if the calls succeeds. An example of the change is:
    Open file as “bar/foo”.
    Before:
    Inquire whether “./bar/foo”, “bar//foo” or “bar/../bar/foo” is open – it is not. 
    After:
    Inquire whether “./bar/foo”, “bar//foo” or “bar/../bar/foo” is open – it is.
  • In 19.0 compiler version, all procedures with the exception of C_F_POINTER from the intrinsic module ISO_C_BINDING were made PURE per the Fortran 2018 standard.  Interpretation 18/007 declared that making C_F_PROCPOINTER PURE was a mistake.  19.1 complies with this interpretation and makes C_F_PROCPOINTER IMPURE.

Visual Studio Integration Changes

Changes in Online Help format in Microsoft Visual Studio*

The online help format is now browser-based. When you view Intel documentation from the Microsoft Visual Studio Help menu, or when you view context-sensitive help using F1 or a help button in a dialog box or other GUI element, your default browser shows the corresponding help topic. You may encounter some minor functionality issues depending on your default browser. Known issues include:

  • When Set Help Preference is set to Launch in Browser and you hit F1 in Tools>Options>F# Tools or Tools>Options>IntelliTrace, the browser appears twice.
  • Chrome*: When arriving at a topic from Search or Index, the Table of Contents (TOC) does not sync, nor does the Sync TOC link work.
  • Firefox*: The TOC loses context easily. Search is case sensitive
  • Safari*: Response on Windows is slow.

Known Issues

Warning message when running psxevars.bat from Command Prompt.

When running the psxevars.bat script from the Command Prompt to set the compiler environment you will get a warning or error message. This message can be ignored – your environment will work properly after running psxevars.bat. Just ignore the warning messages about “The system cannot find the file specified.”

Ignore it and continue to use the Command Prompt.

Command-Line Diagnostic Issue for Filenames with Japanese Characters

The filename in compiler diagnostics for filenames containing Japanese characters may be displayed incorrectly when compiled within a Windows command shell using the native Intel® 64 architecture compiler. It is not a problem when using Visual Studio or when using the Intel® 64 architecture cross-compiler.

Debugging mixed language programs with Fortran does not work

To enable debugging Fortran code called from a .NET managed code application in Visual Studio 2012 or later, unset the following configuration:

Menu Tools ->Options, under section Debugging->General, clear the Managed C++ Compatibility Mode check box

For any managed code application, one must also check the project property Debug > Enable unmanaged code debugging.

Internal Compiler Error(s) involving PARAMETER constants and /debug-parameters /debug Compiler options

The use of PARAMETER constants along with the /debug-parameter and /debug options may cause an internal compiler error.

The following example demonstrates usage that triggers an internal error:

module sample_mod
    implicit none
    integer, parameter :: isize=32  
    
    contains

    subroutine example1 
        call example2(isize)
    end subroutine example1 

    subroutine example2(jsize)
        integer, intent(in) :: jsize
        write(*,*) jsize
    end subroutine example2

end module sample_mod

It is possible to experience several internal errors during a build attempt for the Debug configuration under Visual Studio where it is common to have /debug-parameter and /debug options enabled simultaneously.

You can work-around the defect by either:

  1. Under Visual Studio, disabling the /debug-parameters option under: Properties > Fortran > Debugging > Information for PARAMETER Constants set to None
  2. Under Visual Studio, using only minimal /debug information (i.e. Properties > Fortran > Debugging > Information set to Line Numbers Only) with any setting for /debug-parameters (see the property setting in #1 above).
  3. On the compiler command-line, removing all occurrences of the /debug-parameters from compiler command-line or within application build scripts when using /debug:full
  4. On the compiler command-line, using /debug:minimal with any setting for /debug-parameters on the compiler command-line or within application build scripts.

Coarray Fortran 32-bit doesn't work on 64-bit Microsoft* Windows

Coarray Fortran 32-bit doesn't work on Microsoft* Windows 10 or Microsoft* Windows Server 2012 R2 (only on 64-bit OS)  due to required utilities “mpiexec.exe” and “smpd.exe” not working properly. It is a compatibility issue. Please refer to
Coarray Fortran 32-bit doesn't work on 64-bit Microsoft* Windows for more details.

Fortran Coarray Application Hang After Executing FAIL IMAGE

The current FAIL IMAGE implementation has a known issue that manifests after the FAIL IMAGE statement is executed.  Please refer to the article for more details.

Microsoft Visual Studio 2017 Notes

Microsoft Visual Studio 2010* brought several changes that primarily affect building of mixed-language applications where the main program is in C or C++. These changes were carried forward into Visual Studio 2017.

Configuring Microsoft Visual C++ to Reference Intel® Fortran Run-Time Libraries

  1. In Visual Studio, with a solution open that contains a C++ project, select View > Property Manager.  If you do not see Property Manager under the View menu, you will find it under View > Additional Windows.  The Property Manager window will appear. Note that this is not Properties Window or Properties Pages.
  2. Click on the triangles or + signs to expand the property tree under the Debug|Win32 configuration
  3. Double click on Microsoft.Cpp.Win32.user
  4. Select VC++ Directories
  5. Click in the field to the right of "Library Directories"
  6. Click the triangle that appears to the right and select <Edit...>
  7. Click the New Line button or press Ctrl-Insert
  8. In the new field that appears, type:

    $(IFORT_COMPILER19)\compiler\lib\ia32
  9. Click OK, OK
  10. In the Visual Studio toolbar, select File > Save All

If you will be building Intel® 64 (x64) configurations:

  1. Back in the Property Manager, expand the Debug|x64 configuration
  2. Double click on Microsoft.Cpp.x64.user
  3. Select VC++ Directories
  4. Click in the field to the right of "Library Directories"
  5. Click the triangle that appears to the right and select <Edit...>
  6. Click the New Line button or press Ctrl-Insert
  7. In the new field that appears, type:

    $(IFORT_COMPILER19)\compiler\lib\intel64
  8. Click OK, OK
  9. In the Visual Studio toolbar, select File > Save All

Click on the Solution Explorer tab, or press Ctrl-Alt-L, to make it visible again.

If you do not see the Microsoft.Cpp.x64.user property page listed for the x64 configuration, right click on Debug|x64 and select Add Existing property Sheet.  Browse to the location which contains the MsBuild 4.0 property pages.  

On Windows 10, it is typically:

C:\Users\<username>\AppData\Local\Microsoft\MSBuild\v4.0

You may need to enable viewing of hidden files and folders to see these paths.

Select Microsoft.Cpp.x64.user.props and click Open.  Now follow the steps above.

Adjusting Project Dependencies

If you are converting a project from an earlier version of Visual Studio and had established Project Dependencies, these are converted to References by Visual Studio 2017.  A Fortran project that is referenced by a C/C++ project will prevent the C/C++ project from building, with an MSB4075 error.  To solve this:

  1. Right click on the C/C++ project and select References.
  2. If any Fortran project is shown as a reference, click Remove Reference.  Repeat this for all Fortran projects shown as a reference. Click OK.
  3. Repeat the above steps for any other C/C++ project

Now you have to reestablish project dependencies.

  1. Right click on the C/C++ project and select Project Dependencies. 
  2. Check the box for each project that is a dependent of this project.
  3. Click OK.
  4. Repeat the above steps for any other C/C++ project that has dependencies.

"No apps are installed to open this type of link (file)" when viewing Parallel Studio XE documentation under Microsoft Visual Studio* IDE

When no browser is registered as the handler for .htm* files, viewing documentation under the IDE via Help > Intel Compilers and Libraries can result in an error popup indicating "No apps are installed to open this type of link (file)".

To resolve this issue, select the preferred browser for the file type .htm under either Control Panel > View by: large (or small) icons > Default programs >  Associate a file type or protocol with a program / Set your default programs    -or-    Settings > System > Default Apps > Choose Default Apps by File type. 

Intel® Fortran Compiler for Windows* integration to Visual Studio 2017* issues

There are different integration issues observed with Microsoft* Visual Studio 2017. Problems are intermittent and not reproducible on every system. Please refer to Intel® Software Development Tools Integration to Microsoft* Visual Studio 2017 Issues for details.

Empty class view of Fortran Project

User can encounter the issue with empty class view of Fortran Project. The workaround is to manually delete all existing intermediate files (.fdz and others) and ensure that following setting are enabled in Tools ->Options -> Text Editor -> Fortran ->Advanced:

  • “Collect Call/Callers graph information” and “Collect Object Browser information” are set to True.
  • “Disable Database” is set to False.

Fortran Debugger in Microsoft* Visual Studio 2017 issues

When debugging a Fortran program Microsoft* Visual Studio 2017 version 15.7.x or version 15.8.x crashes. In addition there is another issue that Fortran array values are not visible at a breakpoint. Please find this article for more details.
