From 5f08ba100e97f677424971e30d8643d885c92c72 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Sat, 30 May 2015 16:19:11 +0200 Subject: [PATCH] package/sconeserver: fix static link with openssl When linking statically, the order of libraries on the linker command line is important, and sconeserver got it wrong. Also, sconeserver does not use pkg-config, so it misses the private libs of -lcrypto, which is linking with -lz. Fix that: - add a patch to configure.in to fix the order of libraries; - forcibly pass -lz when linking statically with openssl. Note: we were already reconfiguring sconeserver, because it comes from the github repository.
