/WX (Treat Linker Warnings as Errors)



/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) 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.
