Intel® Fortran Compiler 16.0 User and Reference Guide
Intel® Visual Fortran 10.x projects require conversion to the format used by Intel® Fortran 14.0 and later to be used with Visual Studio* integration. When you open a 10.x project in later versions of Intel® Fortran, a dialog box displays, asking you to confirm the conversion. If you select No, the project will not be loaded. If you select Yes, the project is converted and opens in the Visual Studio* IDE.
A 10.x project opened in Intel® Visual Fortran 11.0 or later cannot be subsequently opened again in Intel® Visual Fortran 10.x.
11.x projects or later open in Intel® Fortran 14.0 without any conversion.
The following applies to projects that were created with earlier versions of Intel® Visual Fortran or with Compaq* Visual Fortran and require conversion.
Intel® Fortran supports the following types of project conversions:
Intel® Visual Fortran 7.x projects to Intel® Visual Fortran 8.x (and later) projects.
Compaq* Visual Fortran 6.x projects to Intel® Visual Fortran 8.x (and later) projects.
Within these major project conversion categories, a number of different conversion scenarios are possible, depending on your version of Microsoft Visual Studio*. For example, a Compaq* Visual Fortran 6.0 project built in the Microsoft Developer Studio* 98 environment can be converted to an Intel® Fortran 14.0 project in the Visual Studio* environment.
Some general conversion principles apply:
It is good practice to make a copy of the project before doing conversions.
Intel® Fortran projects are created and built in a particular version of Visual Studio*. If you open the project in a later version of Visual Studio*, you are prompted to convert the solution. Once converted, a solution cannot be used in its previous environment.
Compaq* Visual Fortran 6.x projects can be converted to Intel® Fortran projects in Visual Studio* 2010, 2012, 2013 or 2015 environments. Fortran-only projects are simpler to convert.
Project conversion support is provided for Compaq* Visual Fortran Version 6.x only. Compaq* Visual Fortran projects created with earlier versions may not convert correctly.
Conversion of Compaq* Visual Fortran projects is not supported if you are using the Microsoft Visual Studio* 2013 Shell. Instead, create a new Intel® Fortran project and add your source files to it.
Fortran source files, resource files, and MIDL files lose any custom build step information when converted from Compaq* Visual Fortran to Intel® Fortran. For other file types, custom build steps will be propagated during the project's conversion.
Conversion of Fortran and C/C++ mixed language projects results in the creation of two separate projects (a Fortran project and a C/C++ project) in a single solution.
Intel® Fortran projects that are created with a point release (for instance, 14.x) are typically backward compatible to the first release of that number (in this case, 14.0). Projects are not backward-compatible between major release numbers.
