From 25400090b1e20b4c98d72f3e427257435c9c0b91 Mon Sep 17 00:00:00 2001 From: Joe Hershberger Date: Tue, 19 May 2015 13:21:23 -0500 Subject: [PATCH] moveconfig: Print a message for missing compiler A common case for failed builds is a missing compiler. Print a message for that case to tell the user concisely which compiler was expected that was not found. This patch also has the effect of not printing build errors any longer. The next patch will add a switch to optionally bring that back.
