µVISION: Build Target Re-Translates NOAMAKE Files

Information in this article applies to:

  • C166 Version 4.20
  • C251 Version 3.20
  • C51 Version 6.20
  • µVision Version 2.20


µVision is retranslating (re-compiling) C files in my project when I use Project - Build target. I have made no changes to the files so the built-in MAKE should check the timestamp and see this. The files do not use the SRC directive or any in-line assembler sections. What can be wrong?


Check to see if the NOAMAKE directive is used somewhere in the compiler or assembler invocation. When you move old projects to µVision, the source files may contain this directive in pragma lines. For example:

#pragma noamake

This directive removes make information from the object files the compiler generates.


Remove the NOAMAKE or NOAM directive from your source files or the Options - Misc dialog entries.
