The libunwind won't show up in menuconfig for aarch64 target because of an unmet BR2_PACKAGE_LIBUNWIND_ARCH_SUPPORTS dependency. This is strange, because: - the official https://github.com/libunwind/libunwind claims that aarch64 linux is fully supported - the minimal handcrafted config featuring libunwind works fine. The minimal config that I've tested was: BR2_aarch64=y BR2_TOOLCHAIN_EXTERNAL=y BR2_PACKAGE_LIBUNWIND=y This occurs on "e30eaeb10e package/qemu: disable curl for the host variant"
Thanks for your bug report, I'll look into this.
