How to make ARM compiler report compilation warnings, as error?

I want the compiler to report all compilation warnings as errors, in ARM C Compiler. Didn't get any help from the Specs. Has anyone tried this? How can I do it?

    You can do it for individual messages using the [url="http://infocenter.arm.com/help/topic/com.arm.doc.dui0348b/CHDJDADE.html"]--diag_error[/url] switch. However, the GNU-style "-Wall" and "-Werror" switches do not work with the ARM compiler so you're out of luck there. I don't know of another way to achieve this using command-line switches.

    One option is to parse the output using your build system. A simple script could be written to check for warning messages and return an error condition if any are found.

    Please post on here if you find a good solution to this, as I (and probably others) would be interested to see how this can be achieved.

    Thanks,
