Subject: [PATCH 01/14] Fix ODR warning in observable.h
Date: Wed, 18 May 2022 12:00:36 -0600 [thread overview]
Message-ID: <20220518180049.2337257-2-tromey@adacore.com> (raw)
In-Reply-To: <20220518180049.2337257-1-tromey@adacore.com>
observable.h triggers an ODR warning because this line:
extern observable<struct target_ops */* target */> target_changed;
... may be the only declaration of "struct target_ops" in scope
(depending on the particular .c file) -- and this declares it in a
namespace, resulting in confusion.
This patch fixes the problem by adding a forward declaration.
Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=22395
