In Ubuntu 16.04 LTS userspace is build for PowerPC 32-bit while kernel selected by the installer depending on PowerPC machine type: * 32-bit for PowerMac G4 (ppc7400) and below * 64-bit for PowerMac G5 and above Thus uname(2) returns ppc64 for 64-bit kernels and 32-bit userspace making build impossible due to missing some of lib64 multilib equivalents in Ubuntu repository. Using setarch(8) override to make whole host look as PowerPC 32-bit can actually help with build but requires mapping for ppc target to their libgpg-error equivalent to fix native build. Build tested on Ubuntu 16.04 LTS host on PowerMac G5 with command: MACHINE=qemuppc setarch ppc bitbake core-image-full-cmdline (From OE-Core rev: e81a5a640a2a00c43796cd47e168c93bb389a6c8) Signed-off-by: Serhey Popovych <serhe.popovych@gmail.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
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.
