[cfe-dev] Undeclared builtin identifiers in C++

[Oscar Neilson]

> With files that use standard library types I get errors about
> undeclared builtin identifiers:

I wasn't calling InitializeBuiltins on the Preprocessor BuiltinContext
but on one I constructed to pass in to my ASTContext. Correcting this
fixes the errors.

------------------------------------------------------------
  preprocessor.getBuiltinInfo().InitializeBuiltins(preprocessor.getIdentifierTable(),
						   preprocessor.getLangOptions());
------------------------------------------------------------
