From 4d6e2902f140845dce75121ba394655f8aca7d9a Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Fri, 12 Dec 2014 22:27:48 +0100 Subject: [PATCH] package/nettle: fix shared-only build Changeset f1d3e09 (Build shared libraries only as the default) broke the nettle package. nettle really wants to statically link its tools, examples and testsuite against its own libraries. But for a shared-only build, static libraries are not even built, so the build breaks when trying to link any of them. Fix that in two ways: - the proper way, by using whatever libraries are available, with a preference toward using shared libraries; - disabling both examples and testsuite since we do not need them. Fixes numerous build failures: http://autobuild.buildroot.net/results/e93/e93da743c5b84b1bb6274aeee3fe3b52962c560c/ http://autobuild.buildroot.net/results/51d/51d0138ff39c45603315dcedf1f654c18604e1a8/ http://autobuild.buildroot.net/results/521/521d979658e402103f1a18fcfeab3f9705f0c000/ ...
