From 02640f014719a994e2e538b2cb6376a189cd39de Mon Sep 17 00:00:00 2001 From: Kevin Darbyshire-Bryant Date: Sat, 4 Apr 2020 09:20:08 +0100 Subject: [PATCH] umdns: suppress address-of-packed-member warning MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit gcc 8 & 9 appear to be more picky with regards access alignment to packed structures, leading to this warning in dns.c: dns.c:261:2: error: converting a packed ‘struct dns_question’ pointer (alignment 1) to a ‘uint16_t’ {aka ‘short unsigned int’} pointer (alignment 2) may result in an unaligned pointer value [-Werror=address-of-packed-member] 261 | uint16_t *swap = (uint16_t *) q; Work around what I think is a false positive by turning the warning off. Not ideal, but not quite as not ideal as build failure.
