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.
