From 0728d3076b4c51ae1f58892a463d5e522ed8b044 Mon Sep 17 00:00:00 2001 From: =?utf8?q?J=C3=A9r=C3=A9mie=20Galarneau?= Date: Fri, 10 Jan 2014 16:38:05 -0500 Subject: [PATCH] Pass the CC variable to the example Makefiles MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Cross-compilation fails when using the --host configure option since the cross-compiler is not invoked by the hand-made Makefiles in doc/examples. The CC variable must be passed explicitly to ensure the host's default compiler is not invoked.
