Arm compiler:need help.. Question regrading recompilation of source file

Note: This was originally posted on 20th April 2011 at http://forums.arm.com

Hi Guys,


In Our  Build system,  a source file is recompiled irrespective of there file contents changed or not  . So In such case can we know from objects/Libraries   header's  that its source contents has been changed or not.( i need this info to know the object's/Libs that really changed(source change) comparing  to  Base build. )

I feel Time stamp doesn't help as the objects are regenerated with out any changes in source file contents .


Thanks for reading my Post.
