SYMPTOMS

When specifying linker options from the CL command line, the word "link" must be in all lowercase letters. If the word "link" is not all lowercase, the error that occurs is either:

Command line warning D4002 : ignoring unknown flag '-xxxx'

-or-

LINK : fatal error L1093: xxxx.OBJ : object not found

NOTE: xxxx is the four letters keyed in after the "/" (forward slash) or the "-" (hyphen).

RESOLUTION

Retype the command line, ensuring "link" is typed in all lowercase letters.
