Subject: Re: GCC/clang warning incompatibility with unused private member variables
Date: Fri, 11 Jun 2021 23:14:47 +0100	[thread overview]
Message-ID: <YMPgV7XbKnXGHgwk@redhat.com> (raw)
In-Reply-To: <5f5ddb1f-39f7-d858-e1c5-afff73043df3@faehling.com>

Here's another #pragma solution to your problem:

class Test {
# pragma GCC diagnostic push
# pragma GCC diagnostic ignored "-Wpragmas" // so GCC ignores next line
# pragma GCC diagnostic ignored "-Wunused-private-field"
     int a_;
# pragma GCC diagnostic pop
     void b() {};
};

First tell GCC not to warn about the warning option that it doesn't
recognize, then use that option to tell clang to not warn about the
unused member.
