Subject: [dpdk-dev] [PATCH 00/10] Enable DPDK core build with gcc 7
Date: Thu,  4 May 2017 16:38:12 +0100	[thread overview]
Message-ID: <20170504153822.19461-1-bruce.richardson@intel.com> (raw)

Since GCC 7 is now yesterday's news :-), I figured we should try and make
DPDK compile successfully with that new version. The main difficulties are
because of new warnings being triggered.

* New warnings for fall-though in case statements
* New warnings for possible truncation using snprintf
* New warnings about uninitialized values.

This set of patches fixes or works around those new issues, fixing a couple of
bugs in the process, so that DPDK can compile using gcc 7.

NOTE: this set only covers the basic DPDK libs, apps and tests. It does not
cover the example apps, which still have issues.

Bruce Richardson (10):
  mk: adjust gcc flags for new gcc 7 warnings
