Created attachment 332172 [details, diff] libvpx-1.1.0-arm-hardfp.patch this is kind of related to bug #323815. problem is that softfp flags are appended to ${CFLAGS}, which causes failure in pthread detection as /usr/include/gnu/stubs.h is included, which tries to include stubs-soft.h which does not exist on hardfloat (it's called gnu/stubs-hard.h).
I could confirm that this patch works fine On my pandaboard, with armv7a-hardfloat-linux-gnueabi- profile my make.conf settings as follow: PANDA_TUNE="-march=armv7-a -mtune=cortex-a9 -mfloat-abi=hard" CFLAGS="-O2 -pipe ${FPU_TUNE} ${PANDA_TUNE} ${DEBUG}" CXXFLAGS="${CFLAGS}" without this patch, it will force to softfloat by default, thus come to cflags as follow which is wrong: armv7a-hardfloat-linux-gnueabi-as --defsym ARCHITECTURE=7 -mfpu=neon -mcpu=cortex-a8 -mfloat-abi=softfp it overwrite the one from /etc/portage/make.conf thus got following wired error:

this patch doesn't seem to apply and looking at the configure.sh it is completely different than this patch for version 1.1.0, not sure how this patch was made. Looking at the libvpx configure.sh it looks like upstream makes a lot of assumptions and forces wierd cflags and we should get this fixed upstream.
Created attachment 337348 [details, diff] libcpx-1.1.0-arm-hardfp.patch Works for me. But I've made some improvments to patch, to make it more sane, but it uses grep now... It makes build/make/configure.sh to check if some of cflags are already specified, and only if not it adds something from itself.
