Subject: [PATCH v2 2/3] erofs-utils: introduce --enable-debug
Date: Sat, 22 May 2021 12:35:01 +0800 [thread overview]
Message-ID: <20210522043502.11975-3-xiang@kernel.org> (raw)
In-Reply-To: <20210522043502.11975-1-xiang@kernel.org>
This adds --enable-debug to explicitly specify debugging mode.
It's disabled by default, which means NDEBUG macro is defined instead.
Signed-off-by: Gao Xiang <xiang@kernel.org>
