[quote user="David Breen"]I strongly believe that the compiler is looking in the wrong directory, as the controlsuite folder on my pc is located in my ti folder. It is suggested that I edit the source lookup path to include its location, but should I really have to do this?[/quote]I think what is happening is that when link against a pre-build library, then the debug information in the library refers to the source directories on the computer on which the library was built, rather than the actual location the library is installed on your computer. In that case, you have to point the debugger at the location the library source code is installed on your computer via "source lookup path".
The Debugging Without a Project section of http://software-dl.ti.com/ccs/non-esd/training/CCSv5-TipsAndTricks.pptx describes the options for setting the Source Lookup Paths.
