This package has been excluded from building if the toolchain is affected by gcc bug 85180. To be consistent with how we deal with this issue in other packages, we re-enable the package and instead work around the issue by building with -O0, since gcc bug 85180 manifests itself only when optimization is enabled. To achieve this: - add --disable-optimizations to EXTRA_OPTS, which gets passed down to the built-in libav library - pass -O0 to CFLAGS in CONF_ENV Then we remove 'depends on !BR2_TOOLCHAIN_HAS_GCC_BUG_85180' and its comment if not available from Config.in Signed-off-by: Giulio Benetti [Thomas: tweak CFLAGS logic, improve commit log] Signed-off-by: Thomas Petazzoni --- diff --git a/package/gstreamer/gst-ffmpeg/Config.in b/package/gstreamer/gst-ffmpeg/Config.in index 1e95d016f6..32bfdd53c6 100644 --- a/package/gstreamer/gst-ffmpeg/Config.in +++ b/package/gstreamer/gst-ffmpeg/Config.in @@ -5,7 +5,6 @@ config BR2_PACKAGE_GST_FFMPEG depends on !BR2_MIPS_CPU_MIPS32R6 && !BR2_MIPS_CPU_MIPS64R6 # triggers https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65151 on sh depends on BR2_TOOLCHAIN_GCC_AT_LEAST_5 || !BR2_sh - depends on !BR2_TOOLCHAIN_HAS_GCC_BUG_85180 select BR2_PACKAGE_GST_PLUGINS_BASE help GStreamer plugin containing one plugin with a set of @@ -29,6 +28,3 @@ endif comment "gst-ffmpeg needs a toolchain w/ gcc >= 5" depends on !BR2_TOOLCHAIN_GCC_AT_LEAST_5 && BR2_sh - -comment "gst-ffmpeg needs a toolchain not affected by GCC bug 85180" - depends on BR2_TOOLCHAIN_HAS_GCC_BUG_85180 diff --git a/package/gstreamer/gst-ffmpeg/gst-ffmpeg.mk b/package/gstreamer/gst-ffmpeg/gst-ffmpeg.mk index 6f41efb0a5..0d584a15b1 100644 --- a/package/gstreamer/gst-ffmpeg/gst-ffmpeg.mk +++ b/package/gstreamer/gst-ffmpeg/gst-ffmpeg.mk @@ -90,6 +90,14 @@ ifeq ($(BR2_STATIC_LIBS),) GST_FFMPEG_CONF_EXTRA_OPTS += --enable-pic endif +GST_FFMPEG_CFLAGS = $(TARGET_CFLAGS) + +ifeq ($(BR2_TOOLCHAIN_HAS_GCC_BUG_85180),y) +GST_FFMPEG_CONF_EXTRA_OPTS += --disable-optimizations +GST_FFMPEG_CFLAGS += -O0 +endif + +GST_FFMPEG_CONF_ENV += CFLAGS="$(GST_FFMPEG_CFLAGS)" GST_FFMPEG_CONF_OPTS += --with-ffmpeg-extra-configure="$(GST_FFMPEG_CONF_EXTRA_OPTS)" $(eval $(autotools-package))
