Re: How to dump all the warning/error messages list from gcc compiler?

[Xiaopi Liu <liuxiaopi349 at gmail dot com>]

Excuse me for the mis-operation. It is the first time to ask question here.
When I said a unique id corresponding to a warning message, I actually
refer to some other compiler,  like intel compiler.
The warning/remark reported in compiling by using intel compiler has a
corresponding id (a number) for that message.


For GCC, I am now trying to use -fdiagnostics-show-option to show the
diagnostics which can be used to disable that kind of warning message.
I mean I can use Wunused-parameter as unique "id" (not necessarily a number)
for the following kind of message.
main.cpp:7: warning: unused parameter ‘argc’ [-Wunused-parameter]


I assume that each warning message by GCC can be turned off its
corresponding unique diagnostics, and so uniquely identified by that
diagnostics.
Do you agree with this?
