Unresolved symbols building a code composer 3 project in code composer 4
There is a device-specific library you have to include that defines the I/O devices as they are on your cpu, and another library that supplies the 'IQ math' routines. I don't have access to the CCSv3/ezDSP setup I worked with a year or two ago (long weekend!), but I think at least the IQ math library was IQmath.lib, or possibly IQmath.out; the F2808 in that project required including a file with a name something like ml28xx.out. Sorry I can't get these file names right until probably Monday evening, but if you search for ml28* and/or IQmath* in the C:\tidcs tree, you might be able to find them.

On CCSv3, there was a dialog for compiler/linker options where you could name these libraries as part of your project. Not sure where these would be with the new Eclipse based CCSv4. Perhaps the eclipse way of right clicking the project name, and looking for 'build properties' would reveal the dialog you need.
