MORIN" , Steve Dickson Subject: [PATCH nfs-utils v3] configure: use pkg-config to find libtirpc Date: Thu, 27 Nov 2014 20:44:39 +0100 Message-Id: <1417117479-16010-1-git-send-email-yann.morin.1998@free.fr> Sender: linux-nfs-owner@vger.kernel.org List-ID: Currently, we use a custom function to find libtirpc's headers and libraries. This works fine for shared linking. But for static linking, this forgets to link with -lpthread, which is required by libtirpc. A recent patch was sent to libtirpc to add that missing -lpthread in its Libs.private section of its .pc file. Thus, pkg-config will soon be able to return the appropriate libraries. So, use pkg-config to find libtirpc. And for older libtirpc versions, there is no change in behaviour: we're still missing the -lpthread. But once libtirpc has been fixed, we'll automatically get that missing library for free! :-) Remove the --with-libirpc flag as it is no longer needed: pkg-config will provide us with the -I and -L flags, now.
