我正在对几个 python 库进行 bitbaking,并在添加第二个库时收到此警告:
WARNING: The recipe is trying to install files into a shared area when those files already exist. Those files are:
/home/ilya/beaglebone-dany/build/tmp/sysroots/beaglebone/usr/lib/python2.7/site-packages/site.py
/home/ilya/beaglebone-dany/build/tmp/sysroots/beaglebone/usr/lib/python2.7/site-packages/site.pyo
这两个库都使用inherit distutils
。所以就 bitbake 而言这是可以的,但是当我尝试通过 opkg 安装第二个包时,我收到了这个错误:
# opkg install http://yocto.local:8080/python-requests_1.2.0-r0_armv7a-vfp-neon.ipk

两个食谱看起来都是这样的:
DESCRIPTION = "Requests: HTTP for Humans"
HOMEPAGE = "http://docs.python-requests.org/en/latest/"
SECTION = "devel/python"
LICENSE = "Apache-2.0"
DEPENDS = "python"
RDEPENDS_${PN} = "python-core"
PR = "r0"
SRC_URI = "git://github.com/kennethreitz/requests;protocol=git"
S = "${WORKDIR}/git/"
inherit distutils
#NOTE: I'm not 100% sure whether I still need to export these?
export BUILD_SYS
export HOST_SYS
export STAGING_INCDIR
export STAGING_LIBDIR
BBCLASSEXTEND = "native"
我从 pycurl recipe 复制了这个,其中也有我删除的这些行:
do_install_append() {
rm -rf ${D}${datadir}/share
}
最佳答案
要摆脱冲突的 /usr/lib/python2.7/site-packages/site.py
,需要通过这样做来避免传送此文件:
do_install_append() {
rm -f ${D}${libdir}/python*/site-packages/site.py*
}
原始版本的食谱还有另一个问题,它安装的文件只包含 .egg
目录。我无法导入
生成的包。
事实证明,使用 inherit setuptools
而不是 inherit distutils
是可行的。
我不是 Python 专家,但所有 setuptools class就是这样:
inherit distutils
DEPENDS += "python-setuptools-native"
DISTUTILS_INSTALL_ARGS = "--root=${D} \
--single-version-externally-managed \
--prefix=${prefix} \
--install-lib=${PYTHON_SITEPACKAGES_DIR} \
--install-data=${datadir}"
事实证明,某些模块(例如 PyBBIO )不识别 --single-version-externally-managed
,因此您必须使用 inherit distutils
你确实得到了一个工作包。
下面是 python-requests 包的完整配方,如果您打算使用它,它应该很快就会在上游可用。
