Bug ID: 18995
Summary: Strangely worded error message "reference to
non-static member function must be called"
Product: clang
Version: 3.4
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
I received the following error message for C++ code:
{{{
reference to non-static member function must be called
static_cast<derived const *>(this)->eigenvalues<direction>(
}}}
The caret points to the "e" of "eigenvalues".
Although I am familiar with C++, I do not understand the wording of this error
message. I think the wording can be improved.
The immediate meaning seems to be that there is a non-static member function,
and that one must call it, implying that I am trying to do something else with
it. That is wrong; I am actually trying to call it.
I assume that this message wants to say "This looks like a function call for a
non-static member function, but this is not actually a non-static member
function." Additionally, it could tell me what "eigenvalues<direction>"
actually is.
In this case, the issue is that "eigenvalues" exists in both this class and its
superclass, and the C-style cast to the superclass is not accepted by Clang.
(Other compilers accepted it.)
Could you improve the wording of the error message?
