Fixed: MACHINE = "qemux86-64" require conf/multilib.conf MULTILIBS = "multilib:lib32" DEFAULTTUNE_virtclass-multilib-lib32 = "x86" $ bitbake core-image-minimal update-alternatives: libtool has multiple providers with the same priority, please check /path/to/rootfs/usr/lib/opkg/alternatives/libtool for details Both libtool and lib32-libtool have the same priority (as they're the same recipe), so update-alternatives won't deterministically pick a provider. This means you could end up with an image using a 32-bit pkgconfig and 64-bit libtool, for example. Make extended recipes reduce priority by 1 (or 2, 3 ... when there are multiple variants in MULTILIB_VARIANTS) to fix the problem.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
