libs

Tells the compiler which type of run-time library to link to.

IDE Equivalent

Windows: Libraries > Runtime Library
Linux: None

Architectures

IA-32, IntelŪ EM64T, IntelŪ ItaniumŪ architecture

Syntax

Linux: None
Windows:  /libs[:keyword]

Arguments

keyword     Specifies the type of run-time library to link to. Possible values are:
  static Specifies a single-threaded, static library (same as specifying /libs).
  dll Specifies a single-threaded, dynamic-link (DLL) library.
  qwin Specifies the Fortran QuickWin library.
  qwins Specifies the Fortran Standard Graphics library.

Default

/libs:static or /libs The compiler links to a  single-threaded, static run-time library.  

Description

This option tells the compiler which type of run-time library to link to.

The library can be statically or dynamically loaded, multithreaded (/threads) or single-threaded, or debug (/dbglibs) or nondebug.

If you use the /libs:dll option and an unresolved reference is found in the DLL, it gets resolved when the program is executed, during program loading, reducing executable program size.

If you use the /libs:qwin or /libs:qwins option with the /dll option, the compiler issues a warning.

You cannot use the /libs:qwin option and options /libs:dll /threads.

The following table shows which options to specify for different run-time libraries:
