Bug ID: 115440
Summary: unrecognized command-line option '--c++17'; did you
mean '--stdc++17'?
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: driver
Assignee: unassigned at gcc dot gnu.org
Reporter: arthur.j.odwyer at gmail dot com
Target Milestone: ---
This is merely a very minor glitch in an error message. But I keep noticing it
when I accidentally use an EDG-style "--c++11, --c++14, ..." option with GCC
instead of the correct "-std=c++11, -std=c++14, ...".
% g++ --c++17 test.cpp
g++: error: unrecognized command-line option '--c++17'; did you mean
'--stdc++17'?
% g++ --stdc++17 test.cpp
g++: error: unrecognized command-line option '--stdc++17'
Instead of "--stdc++XX" it should be suggesting "-std=c++17" (one dash, equals
sign). (Two dashes "--std=c++XX" does also work, but ~nobody writes that in
real life, so I don't think the driver should suggest that anybody start.)
