From 957ff8198240f8f4e9f1585ecd1c469cb7af3b44 Mon Sep 17 00:00:00 2001 From: Sebastian Kemper Date: Sat, 3 Feb 2018 19:30:34 +0100 Subject: [PATCH] freeswitch-stable: workaround for build failures when gcc 7 is used When gcc 7 is used, -Werror=format-truncation finds snprintf() calls in mod_cdr_mongodb.c and suspects that they may result in truncation. As a result the build fails. Work around this by adding -Wno-error=format-truncation to CFLAGS when gcc support this. JIRA-10939 has been raised upstream to follow up on this.
