python - 在 Yocto bitbake 中为 autotools 设置 python dist-packages 路径

问题描述

我正在尝试为使用自动工具配置 Makefile 的项目编写 bitbake 文件。

### tizonia.bb

LICENSE = "LGPL-3.0"
LIC_FILES_CHKSUM = "file://COPYING.LESSER;md5=e6a600fd5e1d9cbde2d983680233ad02"

DEPENDS = "${PYTHON_PN}-modules"

PYPI_PACKAGE = "soundcloud"

inherit pypi setuptools

RDEPENDS_${PN} = "${PYTHON_PN}-modules"

在调用脚本的do_configure步骤中configure，我收到以下错误消息：

| checking for python2.7... (cached) /home/developer/build-webos-ose/BUILD/sysroots/x86_64-linux/usr/bin/python-native/python

如您所见，configure用于sysroots/x86_64-linux/usr/lib/python2.7/site-packages查找modules，但模块安装在sysroots/raspberrypi3/usr/lib/python2.7/site-packages.

如何在/ call 中设置site-packages路径，使其指向正确的路径？autoconfconfigure

解决方案

请记住，配置脚本是在主机上执行的，它也会查找在主机上编译所需的工具，因此您需要依赖于 python-soundcloud-NATIVE 包（您可能需要使用 BBCLASSEXTEND这个包存在），这意味着该包安装的内容将自动填充在 recipe-sysroot-native/x86_64-linux/usr/lib/python2.7/site-packages 上（因为它依赖于它）这是什么配置脚本也会自动读取。
