/FORCE (Force file output)

  • Cikk

Tells the linker to create an executable even if symbols are undefined or multiply defined.

Syntax

/FORCE[:MULTIPLE|:UNRESOLVED]

Remarks

The /FORCE linker option tells the linker to create an executable image (EXE file or DLL) even if a symbol is referenced but not defined or is defined more than once.

Important

The /FORCE option can create an executable that crashes or misbehaves at runtime if it references an undefined symbol or, when a multiply defined symbol has different definitions, if it invokes an unexpected definition in context.

The /FORCE option can take an optional argument:

  • Use /FORCE:MULTIPLE to create an output file whether or not LINK finds more than one definition for a symbol.

  • Use /FORCE:UNRESOLVED to create an output file whether or not LINK finds an undefined symbol. /FORCE:UNRESOLVED is ignored if the entry point symbol is unresolved.

/FORCE with no arguments implies both /FORCE:MULTIPLE and /FORCE:UNRESOLVED.

The linker won't link incrementally when the /FORCE option is specified.

If a module is compiled with /clr, the linker ignores the /FORCE option.
