cairo, harfbuzz: rework atomic dependencies

2016-02-06T10:16:00+00:00

This commit handles the reverse dependency tree of cairo in terms of atomic dependencies. There are two main changes: - cairo in fact no longer needs atomic operations. It can perfectly build without any __sync built-in, as was tested using an ARC toolchain without atomics, and a SPARC toolchain. Optionally, Cairo can use the __atomic builtins provided by gcc >= 4.7, so support for this is added as well. Thanks to this change, the BR2_ARCH_HAS_ATOMICS dependency is removed from cairo and all its reverse dependencies. - harfbuzz does require the __sync built-in for 4 bytes integers, so we add a dependency on BR2_TOOLCHAIN_HAS_SYNC_4 to harfbuzz and all its reverse dependency, the main one being the pango package. Due to this, the vast majority of gtk-related packages are moved to a dependency on BR2_ARCH_HAS_ATOMICS (which used to be due to cairo) to a dependency on BR2_TOOLCHAIN_HAS_SYNC_4 (due to pango -> harfbuzz). In detail: - cairo Remove BR2_ARCH_HAS_ATOMICS dependency, link against -latomic when gcc >= 4.8 in order to use the __atomic functions. - harfbuzz Add dependency on BR2_TOOLCHAIN_HAS_SYNC_4 - cairomm, gst-plugins-good, gst1-plugins-good, libgdiplus, libsvg-cairo, weston Remove BR2_ARCH_HAS_ATOMICS dependency (since cairo no longer needs atomics) - enlightenment, cwiid, gst-plugins-bad, gst-plugins-base, gst1-plugins-bad, gst1-plugins-base, gtkmm3, libevas-generic-loaders, libfm, libgail, libgtk2, libgtk3, librsvg, openbox, opencv, opencv3, pango, pangomm, pcmanfm, pinentry, rrdtool, webkit, webkitgtk24, xscreensaver Switch from a BR2_ARCH_HAS_ATOMICS dependency to a BR2_TOOLCHAIN_HAS_SYNC_4 (they depend on pango, harfbuzz, gtk, or some other related package) - directfb Remove BR2_ARCH_ATOMICS dependency of the BR2_PACKAGE_DIRECTFB_SVG (since cairo can build without atomics), but add a BR2_TOOLCHAIN_HAS_SYNC_4 dependency on BR2_PACKAGE_DIRECTFB itself since it does use __sync built-ins. This replaces the !BR2_sparc dependency. Signed-off-by: Thomas Petazzoni

pulseaudio: remove BR2_ARCH_HAS_ATOMICS dependency

2016-02-06T10:16:00+00:00

pulseaudio is able to either use the atomic __sync builtins from the compiler, or to rely on libatomic_ops for atomic operations. However, since it anyway selects json-c which requires the __sync built-ins, it means using libatomic_ops is useless: even if you use libatomic_ops for pulseaudio, you'd still get a link error in pulseaudio due to the missing __sync built-in for the json-c library. Also, since pulseaudio now inherits the BR2_TOOLCHAIN_HAS_SYNC_4 from json-c, which matches the __sync built-in from pulseaudio, this commit: - Drops the BR2_ARCH_HAS_ATOMICS dependency - Forces pulseaudio to not detect libatomic_ops - Propagates the removal of BR2_ARCH_HAS_ATOMICS dependency to pulseaudio's reverse dependencies.

json-c: needs __sync_val_compare_and_swap_4

2016-02-06T10:16:00+00:00

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.

package/gstreamer/gst-plugins-base: Fix build on x86 if emmintrin.h is available but can't be used

2016-02-01T21:19:02+00:00

I stumbled across this error using a musl-based allyesconfig but I doubt it is related to musl. The autobuilders did not catch this problem yet but the patch I found fits my config (BR2_i386=y, BR2_x86_i586=y) and it solved the problem right away.

package/gstreamer: move comment around, to keep proper indentation

2015-12-28T16:57:35+00:00

In Kconfig, when there is an item (like a comment) between a symbol and its dependees, then the indentation is not in effect. Move the symbol to the top of the file to guarantee the indentation in menuconfig. In this case, it means the gstremaer plugins are not indented below the main gstreamer prompt.
