问题
I want to build the core-image-minimal with yocto and it fails. To set everything up I use the following steps:
sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat cpio python python3 python3-pip python3-pexpect cmake
git clone git://git.yoctoproject.org/poky.git poky.git
cd poky.git
git checkout -b morty remotes/origin/morty
. oe-init-build-env
cd ..
git clone https://github.com/altera-opensource/meta-altera.git meta-altera
cd meta-altera
git checkout -b angstrom-v2015.12-yocto2.0 remotes/origin/angstrom-v2015.12-yocto2.0
Afterwards I add the path to meta-altera to build/conf/bblayers.conf and MACHINE = "cyclone5" to build/conf/local.conf. I would expect, that now bitbake core-image-minimal would run through, but it stops with the following error:
WARNING: qemu-native-2.7.0-r1 do_populate_sysroot: File '/mydirectory/poky.git/build/tmp/sysroots/x86_64-linux/usr/share/qemu/openbios-ppc' from qemu-native was already stripped, this will prevent future debugging!

I got rid of the warnings by adding INSANE_SKIP_qemu-native = "already-stripped" to poky.git/meta/recipes-devtools/qemu/qemu.inc but the error remains. I am using Ubunut 16.04 as my build machine. Any help or tipps are appreciated.
If I continue building, I get an error while building gcc-runtime-6.2.0-r0 do_compile and it stops. I assume that this error is based on the qemu error.
Here is the build config shown in bitbake:
Build Configuration:
BB_VERSION = "1.32.0"
BUILD_SYS = "x86_64-linux"
NATIVELSBSTRING = "universal"
TARGET_SYS = "arm-poky-linux-gnueabi"
MACHINE = "cyclone5"
DISTRO = "poky"
DISTRO_VERSION = "2.2.1"
TUNE_FEATURES = "arm armv7a vfp neon callconvention-hard"
TARGET_FPU = "hard"
meta
meta-poky
meta-yocto-bsp = "morty:924e576b8930fd2268d85f0b151e5f68a3c2afce"
meta-altera = "angstrom-v2015.12-yocto2.0:3cfd56bb15673795435cf7684ef9c723283a6bce"

It looks like you're checking out the Yocto 2.0 branch of the meta-altera layer. Yocto 2.0 was Jethro. You're checking out the Morty branch of Poky which is Yocto 2.2. Try checking out the jethro branch of Poky with by executing the following Git command while in your poky.git folder:
git checkout -b jethro remotes/origin/jethro
