Found a problem with the use of namespaces.
Suppose I have a .ino that includes library files that use namespaces.

My .ino file

#include "MyLibWithNamespace.h"

using namespace MyLibNamespace;

#include "SomeOtherInclude.h"


TypeFromMyLibWithNamespace MyMethodInIno()
{ ... }
...
 

File expanded into a .cpp that gets compiled

#include "MyLibWithNamespace.h"

==>>#include "arduino.h"

TypeFromMyLibWithNamespace MyMethodInIno();
//
//<<==
using namespace MyLibNamespace;

#include "SomeOtherInclude.h"

...
 

==>> <<== marks the added code.

The resulting error is that the compiler cannot find 'TypeFromMyLibWithNamespace' because it was not fully qualified.

Quote:


Because this magic happens behind the scenes it reports the error on a line (of the .cpp) that makes no sense in the .ino - which took a long time to sort out. 

EDIT:
Prefixing the full namespace before the returned type does not fix the problem!
The generated decalration does not copy them over.
