在Yocto Bitbake中为自动工具设置python dist-packages路径

Question

我正在尝试为使用自动工具配置Makefile的项目编写一个bitbake文件。

### tizonia.bb
SUMMARY = "Tizonia Library"
DESCRIPTION = "Tizonia"
LICENSE = "LGPL-3.0"
LIC_FILES_CHKSUM = "file://COPYING.LESSER;md5=e6a600fd5e1d9cbde2d983680233ad02"

SRC_URI = "git://github.com/tizonia/tizonia-openmax-il.git;protocol=https"
SRCREV = "9004bc40b89eeafb04b28fbb2b772e47dd62fdc9"

S = "${WORKDIR}/git"

DEPENDS = "python-dev python-setuptools mediainfo log4c python-pip python-soundcloud"

inherit autotools ccache pkgconfig python-dir pythonnative

RDEPENDS_${PN} = "libstdc++ dbus boost libgcc mediainfo log4c libspotify python-pip python-soundcloud"

### python-soundcloud.bb
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://LICENSE;md5=31fa3a9dc818e0087893d63583d2d21a"

SRC_URI[md5sum] = "40c1d32afd019ed11ec1fbee3e84e31f"
SRC_URI[sha256sum] = "aad2003592cec945f835f158f7b41ba8bf805c5738a2fcc5629668ea1df653d5"

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

正如你所看到的，configure是用sysroots/x86_64-linux/usr/lib/python2.7/site-packages寻找modules，但模块安装在sysroots/raspberrypi3/usr/lib/python2.7/site-packages。

如何site-packages在autoconf/ configure调用中设置路径，使其指向正确的路径？

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对于这个包存在），这意味着该包安装的内容将自动填充到recipe-sysroot-native/x86_64-linux/usr/lib/python2.7/site-packages（因为它依赖于它）上配置脚本也会自动读取。
