I've got a Project with a bunch of frameworks, each of which has a static library version of itself (for compiling command-line tools that also use the code).
Compiling the frameworks goes fine. Compiling one of the static libraries (A Mime-parsing framework) is giving me the rather odd message that a bunch of symbols are ambiguous, but the ambiguity resolves to the same symbol in the error-message...
~/src/E3Mail/Frameworks/E3Mime/E3Mime/Message/MIME/E3AppPkcs7Part.m:57:18: error: reference to 'E3_SMIME_ENVELOPED_DATA' is ambiguous

.
No file inside the module (neither .m or .h) includes the module-header, the definition of the offending symbols looks like:
//
// E3AppPkcs7Part.h
// E3Mime
//
#import <E3Mime/E3CryptoContext.h>
#import <E3Mime/E3MimePart.h>
#import <E3Mime/E3MimeMultipartEncrypted.h>
NS_ASSUME_NONNULL_BEGIN
typedef enum
{
E3_SMIME_COMPRESSED_DATA, // Compressed data
E3_SMIME_ENVELOPED_DATA, // Enveloped data
E3_SMIME_SIGNED_DATA, // Signed data
E3_SMIME_CERTS_ONLY, // Only certificate data
E3_SMIME_UNKNOWN, // Que ?
} E3SMimeType;
...
And when I click on the error adornment in the editor pane, the errors disappear. It still won't build the project, though. I just get the same errors the next time I press CMD-B.
Can't upload a short screen-capture of that, so I put it the movie at http://0x0000ff.co.uk/mov/phantom-errors.mov.
