I use an OpenSuse 13.1 host to build a rootfs for an Atmel SAMA5 board. My defconfig is based on a working config for buildroot 2013.08

Please note, that the error occurs during building the mplayer included ffmpeg-
package. Compiling the buildroot-ffmpeg-package (ffmpeg-2.6.2, BR2_PACKAGE_FFMPEG=y) works without problems.
Comment 1 Thomas Petazzoni 2015-08-06 21:03:43 UTC 
Thanks for your bug report. Can you make sure that the problem still occurs after disabling ccache support and doing a "make clean all" ?

Also:

BR2_EXTRA_GCC_CONFIG_OPTIONS="--with-float=hard --with-fpu=vfpv4-d16"
BR2_TARGET_OPTIMIZATION=" -pipe -mfpu=vfpv4-d16 -mfloat-abi=hard"

are not needed. If you want --with-float=hard, select EABIhf instead of EABI in the Target options. The FPU type is already passed since you selected BR2_ARM_FPU_VFPV4D16=y.

same issue again after "make clean all" without ccache.

Made further tests with and without this options, also tried EABIhf instead of EABI (always "make clean all" after configuration change) without any different result.
Comment 3 Thomas Petazzoni 2015-10-14 12:23:42 UTC 
Your defconfig (with just the post-build script, overlay, custom Busybox config, and the custom cflags removed) builds fine with the current Buildroot master. So I believe that the bug has been fixed (maybe due to the fact that the gcc version has been upgraded).

I'll therefore close the bug. However, if you still see the issue, do not hesitate to re-open it. Thanks!
