Subject: [Buildroot] [PATCH 2/2] libcap: fix static link
Date: Sat, 2 Nov 2013 19:01:34 +0100	[thread overview]
Message-ID: <20131102180134.GJ3542@free.fr> (raw)
In-Reply-To: <1383328047-28945-2-git-send-email-thomas.petazzoni@free-electrons.com>

Thomas, All,

On 2013-11-01 18:47 +0100, Thomas Petazzoni spake thusly:
> With BR2_PREFER_STATIC_LINK, libcap fails to build:
> 
>   http://autobuild.buildroot.net/results/619bceb3491ecd2ed4e1ae552fdb237a0ed2fa47/build-end.log
> 
> This is due to the fact that it still tries to build a shared
> library. This commit fixes that by adding a patch that makes libcap
> provide install-shared/install-static targets. We also now only build
> the $(@D)/libcap subdirectory, so removing the build of the progs
> subdirectory is no longer needed.
