From 7614222ca6cc73aae478d0ed659c0bcedfee4cc3 Mon Sep 17 00:00:00 2001 From: Daniel Elstner Date: Wed, 26 Aug 2015 14:07:39 +0200 Subject: [PATCH] Build: Define feature test macro _DEFAULT_SOURCE This basically makes glibc expose the same set of features as if gcc was invoked without any restricting -std=c* option. Unlike _GNU_SOURCE however, it does not enable GNU-specific extensions. So, with this macro defined the behavior of Linux with glibc should match that of other platforms. --- Makefile.am | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/Makefile.am b/Makefile.am index 0515e80..873883e 100644 --- a/Makefile.am +++ b/Makefile.am @@ -23,7 +23,7 @@ AM_LIBTOOLFLAGS = --silent MAKEFLAGS = --no-print-directory DECODERS_DIR = $(pkgdatadir)/decoders -AM_CPPFLAGS = -D_POSIX_C_SOURCE=200112L -DDECODERS_DIR='"$(DECODERS_DIR)"' +AM_CPPFLAGS = -D_DEFAULT_SOURCE -DDECODERS_DIR='"$(DECODERS_DIR)"' # The tests CFLAGS are a superset of the libsigrokdecode CFLAGS.
