构建 yocto dunfell 时 random.py 中的非法指令

Question

我正在将我的 Yocto 版本从 sumo 升级到 dunfell，但我在包 python3-setuptools-native (v45.2.0-r0) 中收到一个错误，指出它已达到 Illegal instruction.我的 yocto tmp 和 sstate-cache 目录都是新的（即没有 sumo 构建挥之不去）。

这是失败后log.do_compile文件的内容。

DEBUG: Executing shell function do_compile
Illegal instruction (core dumped)
ERROR: 'python3 setup.py build ' execution failed.
WARNING: exit code 1 from a shell command.
ERROR: Execution of '/home/mans/oe-build/am335x-board/tmp/work/x86_64-linux/python3-setuptools-native/45.2.0-r0/temp/run.do_compile.2778959' failed with exit code 1:
Illegal instruction (core dumped)
WARNING: exit code 1 from a shell command.

作为调试问题和获取堆栈跟踪的一种方式，我打开了一个 devshell 并启动了运行 python 并启用了故障处理程序。我基本上是从 setup.py 和运行中手动挑选前几行，但在 import setuptools 上失败了。回溯指向 python 安装中 random.py 的第 69 行（即不在 python3-setuptools-native 包中）。

第 69 行 random.py

RECIP_BPF = 2**-BPF

故障处理程序输出

有人在构建 yocto 时看到过类似的东西吗？

Answer 1

这是 glibc-2.32 中的一个工具链错误，使其成为非原生工具链：https://bugzilla.yoctoproject.org/show_bug.cgi?id=14215

作为解决方法，您可以禁用非原生，例如通过 INHERIT_remove = "uninative" 在您的配置中

Answer 2

在我的例子中（Ubuntu 20 编译 Yocto 3.0），@tim 的解决方案不起作用。相反，我更改了这个文件：

poky/meta/conf/distro/include/yocto-uninative.inc

至：

UNINATIVE_URL ?= "http://downloads.yoctoproject.org/releases/uninative/2.10/"
UNINATIVE_CHECKSUM[aarch64] ?= "645e5c50b2b48aabb8b10f783a9f94b4b7c5ddc7cfceb5386d43b86d30253202"
UNINATIVE_CHECKSUM[i686] ?= "233e09b5ff30e15341232a0c16fa8448ff31dccb8f3f3e2ad3948cdac8c4a598"
UNINATIVE_CHECKSUM[x86_64] ?= "04333677f81990ce2cf55c3bc256cd84a66085d18fc95ccddfab8581e4aec014"

从 yocto 补丁复制而来：
