Hi!

I tried parse only this constructions without some #include constructions.

And parse typedef is correct.

I found the problem to be different.

Preprocessor try find #include "file.h" - and could not find ,so generate
"fatal error: No such file" and preprocessor has been terminated. Therefore,
next preprocessing templates and other has been stop. And therefore, I received
invalid declaration.

I found fixing:
-Need will doing that preprocessor not terminate via "fatal error: No such
file".

I changed the code (I added the construction to the custom
ParseDeclarationAction class, which is inherited from ASTFrontendAction):

CI.getPreprocessor().SetSuppressIncludeNotFoundError(true);

In result I have class:

class ParseDeclarationAction : public ASTFrontendAction
{
public:
  virtual unique_ptr<ASTConsumer> CreateASTConsumer(CompilerInstance &CI,
StringRef InFile) {
    CI.getPreprocessor().SetSuppressIncludeNotFoundError(true);
    return unique_ptr<ASTConsumer>(new
ParseDeclarationConsumer(&CI.getASTContext()));
  }
};

I think may problem will be help other clang users.

This task is resolved.

Thank you for your support.

Best Regards,
Ivan.
