Intel® Fortran Compiler 16.0 User and Reference Guide

Specifying Consistent Library Types

This topic only applies to Windows*.

There are a number of Visual C++* run-time libraries that offer the same entry points but have different characteristics. The default Visual C++* library is libc.lib, which is single-threaded, non-debug, and static.

The Intel® Visual Fortran and Microsoft* Visual C++* libraries must be the same types. The incompatible types are listed below.

The default Intel® Visual Fortran libraries depend on the project type:

Fortran Project Type

Default Libraries Used

Fortran Console

Static, single-threaded libraries ifcore.lib and libc.lib

Fortran Standard Graphics

Static, multithreaded libraries ifcoremt.lib and libcmt.lib

Fortran QuickWin

Static, multithreaded libraries ifcoremt.lib and libcmt.lib

Fortran Windows

Static, multithreaded libraries ifcoremt.lib and libcmt.lib

Fortran DLL

Dynamic-link libraries ifcoremd and msvcrt (and their import libraries)

Fortran Static Library

Static, single-threaded libraries ifcore.lib and libc.lib

Pure Fortran applications can have mismatched types of libraries. One common scenario is a Fortran QuickWin application that links with a Fortran Static library. Fortran QuickWin (and Fortran Standard Graphics) applications must use the static, multithreaded libraries, and by default, Fortran Static libraries are built using static, single-threaded libraries. Because this causes a conflict, the Fortran Static library and the QuickWin application must both be built using static, multithreaded libraries.

Similarly, different C/C++ applications link against different C libraries. If you mix the different types of applications without modifying the defaults, you can get conflicts. The debug version of a library has a letter d appended to its base file name:

When using a Debug configuration, Visual C++* selects the debug libraries.

The Intel® Visual Fortran Compiler does not select debug libraries for any configuration, but provides settings that allow you to request their use. To specify different types of Fortran libraries in the IDE, select Project > Properties, then select the Libraries category on the Fortran tab:
