构建 yocto dunfell 时 random.py 中的非法指令答案

【问题标题】：Illegal instruction in random.py when building yocto dunfell构建 yocto dunfell 时 random.py 中的非法指令
【发布时间】：2021-03-18 13:11:35
【问题描述】：

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（即没有相扑构建挥之不去）。

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 并开始运行启用了故障处理程序的 python。我基本上从setup.py 中挑选了前几行并手动逐一运行它们，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）。

random.py 的第 69 行

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？

【问题讨论】：

标签： python python-3.x setuptools yocto cpython

【解决方案1】：

这是 glibc-2.32 中的一个工具链错误，它进入了 uninative 工具链：https://bugzilla.yoctoproject.org/show_bug.cgi?id=14215

作为一种解决方法，您可以禁用 uninative，例如INHERIT_remove = "uninative" 在你的配置中

【解决方案2】：

就我而言（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

到：

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：

https://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?h=dunfell&id=cdda267645506b2471a1085b42de3cdfa238d8d5

【讨论】：

这已在上面 Felix 发布的链接上的 dunfell 分支上修复，因此接受他的答案，因为这是最正确的答案。
如果您使用 git for poky，您可以通过 git cherry-pick cdda267645506b2471a1085b42de3cdfa238d8d5 将补丁应用到您的版本。这在宙斯中对我有用。
