Even if that bug is fixed, this error message could be better. The error is using a single colon instead of two colons. "expected primary-expression" is not helpful to the user. Firstly, as in PR 39858, what is missing is an expression, not a primary-expression. Secondly, the colon is clearly out of place; if we found an expression, we would still fail. In this case, we actually know that we just saw a NAMESPACE_DECL. We can give a better error message in this context. -- Summary: C++: Duplicated and unhelpful error for "c:n" Product: gcc Version: 4.5.0 Status: UNCONFIRMED Severity: trivial Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: ian at airs dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39859 ^ permalink raw reply [flat|nested] 3+ messages in thread
