【问题描述】：

我正在尝试使用 yocto 生成 SDK。

硬件：x64

通用元情报层

图像：核心图像最小。

我在 conf 文件中启用了 multilib 以支持 32 位库。

require conf/multilib.conf
MULTILIBS = "multilib:lib32"
DEFAULTTUNE_virtclass-multilib-lib32 = "x86"

当我运行以下命令时：bitbake -c populate_sdk core-image-minimal，我在最后阶段收到以下错误。

如何解决此错误。我在 yocto 邮件列表中看到了类似的帖子..

https://lists.yoctoproject.org/pipermail/yocto/2017-October/038338.html

感谢您的宝贵时间。感谢您的努力。

【问题讨论】：

SDK_MACHINE 变量的值是多少？
我在 local.conf 中没有看到任何这样的变量
我分配了 SDKMACHINE ?= "i686"，即使我得到了同样的错误..
我该如何解决这个..有什么提示

【解决方案1】：

我的一位同事通过像这样更改conf/local.conf 解决了这个问题：

# packaging
PACKAGE_CLASSES ?= "package_ipk"
#PACKAGE_CLASSES ?= "package_deb package_ipk"

似乎 package_deb 是问题的一部分。

当然，它留下的问题与它回答的一样多，但也许足以让你超越当前的障碍。

这真的对我有用。很奇怪。非常感谢。
