From 8ea392b84e3a02a7827fc3b97b541d3c41c83935 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Tue, 2 Feb 2016 16:31:22 +0100 Subject: json-c: needs __sync_val_compare_and_swap_4 While json-c itself builds fine on platforms that don't provide the __sync atomic built-ins, it does use them. json-c doesn't fail to build because only a library is built, so such function calls are left unresolved. But as soon as it gets used in another package linked in a program, linking will fail due to the missing __sync_val_compare_and_swap_4() function. To fix this, we make json-c depend on BR2_TOOLCHAIN_HAS_SYNC_4, and propagate to the reverse dependencies: - json-c - fastd - pulseaudio - efl - espeak - gst-plugins-good - gst1-plugins-good - mpd - rsyslog - ubus Note that pulseaudio already had a BR2_ARCH_HAS_ATOMICS dependency, which we are keeping for the moment, and will clean-up in a subsequent commit. This commit will also fix packages that could optionally use json-c, and therefore fixes build failures like: http://autobuild.buildroot.org/results/4fe/4feaa9089ee9a183c5086b791bea35c0156945af/ Signed-off-by: Thomas Petazzoni Reviewed-by: "Yann E.
