Subject: [Buildroot] [RFC PATCH 4/4] clang: Fix undefined reference to dladdr error
Date: Tue, 29 Sep 2020 11:26:18 +0100	[thread overview]
Message-ID: <20200929102618.28571-5-qais.yousef@arm.com> (raw)
In-Reply-To: <20200929102618.28571-1-qais.yousef@arm.com>

For some reason the cmake::find_library() can't detect the path to dl,
so we end up not including the right library when linking, hence the
error above.

Could be a hack/workaround to the real problem.
