The summary says it all. I am using a project that I last used about 4 months ago and this problem didn't exist. Since then I've moved computers and installed a new copy of uVision. My old computer is NOT available to test it on.
I have made sure TZ is not defined anywhere, that Create Batch File is not checked, and Use Cross-Module Optimization is not checked.
These are the only things I could find on the issue after a good amount of Google and Keil Forum checking. Any other ideas? Thank you!
Hasn't there been some issues with generation of list files resulted in full rebuilds?
Ding ding ding. We have a winner! Thanks a lot, this was driving me nuts.
Turning on C Compiler Listing will make it recompile but not return the preprocessor, while turning on C Preprocessor Listing will make it rerun both preprocessor and compiler.
I also checked with an old coworker who is still running our original version and he is using 4.70, so somewhere in between that got broken.
Thanks again for your quick help.
