I have an unresolved external (warnings L1 / L2) but the linker still creates a target. If I miss the warnings as they scroll past I end up with a target that will reset when it hits the reference. How can I promote the warning to an error or otherwise prevent the creation of the target?
linking... *** WARNING L1: UNRESOLVED EXTERNAL SYMBOL SYMBOL: MY_TYPO_FUNCTION_NAME MODULE: myfile.obj (MYFILE) *** WARNING L2: REFERENCE MADE TO UNRESOLVED EXTERNAL SYMBOL: MY_TYPO_FUNCTION_NAME MODULE: myfile.obj (MYFILE) ADDRESS: 29A0H Program Size: data=202.3 xdata=927 code=11390 creating hex file from "KeilPortEmulator"...

thanks
I agree it would be better if it was an error.
now IMHO the real nuisance is "miss the warnings as they scroll past" I would love to see them listed at the end of the build
I was hoping that there was a linker directive to make L1 and L2 errors?
This doesn't happen in the 166 or ARM tool chains
I have a post build step (symbol processor) that hides these warnings by adding text to the build output. Maybe I could use a wide screen monitor in portrait? :)
Thanks for you help A
In the 166 linking... *** ERROR L127: UNRESOLVED EXTERNAL SYMBOL SYMBOL: PRS_SetxStatus MODULE: .\obj\transprt.obj (TRANSPRT) and ARM linking... ..\obj\RDE\CORTEX-M3_RTX\Rde.axf: Error: L6218E: Undefined symbol fred() (referred from profile.o). Target not created
