openEuler 版本
- 基于Yocto构建的openEuler嵌入式版本 openEuler Embedded
- 目标平台: 树莓派4B (aarch64)
问题现象及影响
运行dnf命令时出现Python库依赖错误，具体报错如下:
raspberrypi4-64 ~ # dnf -v
Traceback (most recent call last):
File "/usr/bin/dnf", line 61, in <module>
from dnf.cli import main
File "/usr/lib64/python3.10/site-packages/dnf/__init__.py", line 30, in <module>
import dnf.base
File "/usr/lib64/python3.10/site-packages/dnf/base.py", line 29, in <module>
import libdnf.transaction
File "/usr/lib64/python3.10/site-packages/libdnf/__init__.py", line 13, in <module>
from . import common_types
File "/usr/lib64/python3.10/site-packages/libdnf/common_types.py", line 10, in <module>
from . import _common_types
ImportError: /usr/lib64/python3.10/site-packages/libdnf/_common_types.so: undefined symbol: _ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE9_M_appendEPKcm, version GLIBCXX_3.4.21
这导致无法使用DNF进行软件包的安装、更新等操作。
复现路径
1. 使用Yocto构建系统编译openEuler树莓派镜像:
- 使用的层:
/usr1/openeuler/src/yocto-poky/meta \ /usr1/openeuler/src/yocto-poky/../yocto-meta-openembedded/meta-oe \ /usr1/openeuler/src/yocto-poky/../yocto-meta-openembedded/meta-python \ /usr1/openeuler/src/yocto-poky/../yocto-meta-openembedded/meta-networking \ /usr1/openeuler/src/yocto-poky/../yocto-meta-openembedded/meta-filesystems \ /usr1/openeuler/src/yocto-poky/../yocto-meta-openeuler/meta-openeuler \ /usr1/openeuler/src/yocto-poky/../yocto-meta-openeuler/bsp/meta-openeuler-bsp \ /usr1/openeuler/src/yocto-poky/../yocto-meta-raspberrypi \ - local.conf中已添加包配置:
#===========the content is user added==================
MACHINE = "raspberrypi4-64"
EXTRA_IMAGE_FEATURES += "package-management"
2. 将镜像烧录到SD卡并启动树莓派
3. 在树莓派系统中执行任何dnf命令都会出现上述错误
已尝试的解决方法
1. 检查libstdc++版本及GLIBCXX符号:
结果显示系统中已包含GLIBCXX_3.4.21及更新版本。
raspberrypi4-64 ~ # strings /usr/lib64/libstdc++.so.6 | grep GLIBCXX
GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2
GLIBCXX_3.4.3
GLIBCXX_3.4.4
GLIBCXX_3.4.5
GLIBCXX_3.4.6
GLIBCXX_3.4.7
GLIBCXX_3.4.8
GLIBCXX_3.4.9
GLIBCXX_3.4.10
GLIBCXX_3.4.11
GLIBCXX_3.4.12
GLIBCXX_3.4.13
GLIBCXX_3.4.14

GLIBCXX_3.4.27
GLIBCXX_3.4.28
GLIBCXX_3.4.29
GLIBCXX_3.4.30
GLIBCXX_DEBUG_MESSAGE_LENGTH
2. 检查库路径和ldconfig缓存:
显示库已正确链接:
raspberrypi4-64 ~ # ldconfig -p | grep libstdc++
libstdc++.so.6 (libc6,AArch64) => /usr/lib64/libstdc++.so.6
3. 检查具体库文件:
结果显示:
raspberrypi4-64 ~ # ls -la /usr/lib64/libstdc++*
lrwxrwxrwx 1 root root 19 Mar 9 12:34 /usr/lib64/libstdc++.so.6 -> libstdc++.so.6.0.30
-rwxr-xr-x 1 root root 1313096 Mar 9 12:34 /usr/lib64/libstdc++.so.6.0.30
-rwxr-xr-x 1 root root 2504 Mar 9 12:34 /usr/lib64/libstdc++.so.6.0.30-gdb.py
