/WX (Treat Linker Warnings as Errors)

The latest version of this topic can be found at -WX (Treat Linker Warnings as Errors).

WX[:NO]

  
## Remarks  
 /WX causes no output file to be generated if the linker generates a warning.  
  
 This is similar to **/WX** for the compiler (see [/w, /W0, /W1, /W2, /W3, /W4, /w1, /w2, /w3, /w4, /Wall, /wd, /we, /wo, /Wv, /WX (Warning Level)](../Topic/-w,%20-W0,%20-W1,%20-W2,%20-W3,%20-W4,%20-w1,%20-w2,%20-w3,%20-w4,%20-Wall,%20-wd,%20-we,%20-wo,%20-Wv,%20-WX%20\(Warning%20Level\).md) for more information). However, specifying **/WX** for the compilation does not imply that **/WX** will also be in effect for the link phase; you must explicitly specify **/WX** for each tool.  
  
 By default, **/WX** is not in effect. To treat linker warnings as errors, specify **/WX**. **/WX:NO** is the same as not specifying **/WX**.
