Bug ID: 68842
Summary: Better error output when template needed before
dependent name
Product: gcc
Version: 4.8.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: davejohansen at gmail dot com
Target Milestone: ---
Created attachment 36985

Example code to demonstrate error
Currently, when a dependent name cannot be correctly resolved and the template
keyword is required, the error output is:
test_template.cc: In instantiation of ‘void do_test() [with int N = 2]’:
test_template.cc:20:14: required from here
test_template.cc:15:15: error: invalid operands of types ‘<unresolved
overloaded function type>’ and ‘int’ to binary ‘operator<’
t.do_nothing<N>(0);
The output is a correct representation of how the compiler is interpreting the
code, but it is not helpful to a developer that doesn't understand the
intricacies of templates and dependent name resolution. It would be nice if a
more meaningful error output was given with at least a hint about the possible
need for the template keyword.
