From: Mathieu Desnoyers Date: Thu, 14 May 2015 15:33:47 +0000 (-0400) Subject: Fix: don't generate incorrect macros for debian/ubuntu version check X-Git-Tag: v2.7.0-rc1~18 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=05732a66bd235ff9ea4e73b5072872e1647775e1;p=lttng-modules.git Fix: don't generate incorrect macros for debian/ubuntu version check When the debian/ubuntu macros are unset, we end up generating macros that have no right hand operand to "+", which seems to break compilation on some compilers, even though it will always be optimized away.
