構建 yocto dunfell 時 random.py 中的非法指令

Question

我正在將我的 Yocto 版本從 sumo 升級到 dunfell，但在 package python3-setuptools-native (v45.2.0-r0) 中出現錯誤，指出它已達到Illegal instruction 。 我的 yocto tmp 和 sstate-cache 目錄都是新的（即沒有相撲構建揮之不去）。

這是失敗后log.do_compile文件的內容。

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.

作為調試問題和獲取堆棧跟蹤的一種方式，我打開了一個 devshell 並開始運行 python 並啟用了故障處理程序。 我基本上從setup.py中挑選了前幾行，並一一手動運行它們，但在import setuptools上失敗了。 回溯指向 python 安裝中random.py的第 69 行（即不在 python3-setuptools-native 包中）。

random.py 的第 69 行

RECIP_BPF = 2**-BPF

故障處理程序 output

有人在構建 yocto 時看到過類似的東西嗎？

Answer 1

這是 glibc-2.32 中的一個工具鏈錯誤，它進入了 uninative 工具鏈： https://bugzilla.yoctoproject.org/show_bug.cgi?id=14215

作為一種解決方法，您可以禁用 uninative，例如通過配置中的INHERIT_remove = "uninative"

Answer 2

就我而言（Ubuntu 20 編譯 Yocto 3.0），@tim 的解決方案不起作用。 相反，我更改了這個文件：

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"

這是從 yocto 補丁復制的：
