So for libhugetlbfs, as I understand things, we rely on "uname -m" to get the architecture, i.e. we are compiling on the host. If "uname -m" is just equal to "arm" we don't know if we are dealing with ARMv4,5,6,7 or whether or not it's big or little endian or even whether or not we have Thumb (for when it's optional). > > The following information: > Build Configuration: > BB_VERSION = "1.20.0" > BUILD_SYS = "x86_64-linux" > NATIVELSBSTRING = "Fedora-13" > TARGET_SYS = "arm-poky-linux-gnueabi" > MACHINE = "beagleboard" > DISTRO = "poky" > DISTRO_VERSION = "1.5" > TUNE_FEATURES = "armv7a vfp neon" > TARGET_FPU = "vfp-neon" > meta > meta-yocto > meta-yocto-bsp = "(nobranch):28e7e4ffa5cd6cdfe02392c60bc42ed396376dcd" > I am not overly familiar with poky, but recipes to cross-compile libhugetlbfs for AArch64 on OpenEmbedded exist at: http://git.openembedded.org/meta-openembedded/tree/meta-oe/recipes-benchmark/libhugetlbfs I see we have "TUNE_FEATURES=armv7a" listed above, does it not make more sense for "uname -m" to equal "armv7l" in your cross build environment? [ To my knowledge, huge pages are only supported upstream for 32-bit ARM LPAE kernels, thus are not generally available for the Beagleboard? ] Cheers, -- Steve ------------------------------------------------------------------------------ HPCC Systems Open Source Big Data Platform from LexisNexis Risk Solutions Find What Matters Most in Your Big Data with HPCC Systems Open Source.
