CCS6.0.1.00040 Editor Flagging non-errors as errors

If there are no errors reported by the compiler in the CCS build console, then this Syntax error is likely coming from the Eclipse indexer that comes built-in with CCS. You can take a look at and adjust the indexer settings and even disable the indexer from Project Properties->C/C++ General->Indexer. There is also a way to disable the indexer markers without disabling the indexer itself. If you disable the indexer completely you will lose the capabilities of code completion and navigation to declaration/definition. However, you can disable the indexer marker by going to Window->Preferences->General->Editors->Text Editors->Annotations and uncheck all three checkboxes for "C/C++ Indexer Markers".
