Hi,
You can solve this error by adding "${workspace_loc:/${ProjName}}" (including quotes) to "Project: Properties: C/C++ Build: Settings: CrossCore SHARC Assembler: Preprocessor: Additional Include Directories". I was still receiving an error at this point, but found that adding a semi-colon after the "'IMPORT..." directive avoided that.
Additionally, it looks like you're using a VisualDSP++ LDF in your CCES project. You will likely need to modify it to use the CCES library names to get this project to build.
Regards,
Craig.
