devtool: unset

devtool: unset 问题

在 Ubuntu 20.04.1 LTS 上进行编译Yocto时报错，出现如下错误：

bb.data_smart.ExpansionError: Failure expanding variable SRCPV, expression was ${@bb.fetch2.get_srcrev(d)} which triggered exception FetchError: Fetcher failure: Fetch command export PSEUDO_DISABLED=1; unset _PYTHON_SYSCONFIGDATA_NAME; export PATH="/home/test/embeded/rockpis/yocto/poky/scripts:/home/test/embeded/rockpis/yocto/poky/build/tmp/work/aarch64-poky-linux/create-ap/git-r0/recipe-sysroot-native/usr/bin/aarch64-poky-linux:/home/test/embeded/rockpis/yocto/poky/build/tmp/work/aarch64-poky-linux/create-ap/git-r0/recipe-sysroot/usr/bin/crossscripts:/home/test/embeded/rockpis/yocto/poky/build/tmp/work/aarch64-poky-linux/create-ap/git-r0/recipe-sysroot-native/usr/sbin:/home/test/embeded/rockpis/yocto/poky/build/tmp/work/aarch64-poky-linux/create-ap/git-r0/recipe-sysroot-native/usr/bin:/home/test/embeded/rockpis/yocto/poky/build/tmp/work/aarch64-poky-linux/create-ap/git-r0/recipe-sysroot-native/sbin:/home/test/embeded/rockpis/yocto/poky/build/tmp/work/aarch64-poky-linux/create-ap/git-r0/recipe-sysroot-native/bin:/home/test/embeded/rockpis/yocto/poky/bitbake/bin:/home/test/embeded/rockpis/yocto/poky/build/tmp/hosttools"; export HOME="/home/test"; git -c core.fsyncobjectfiles=0 ls-remote https://github.com/oblique/create_ap.git  failed with exit code 128, output:

解决方法

修改meta/classes/devtool-source.bbclass文件，如下：

 DEVTOOL_TEMPDIR ?= ""
 DEVTOOL_PATCH_SRCDIR = "${DEVTOOL_TEMPDIR}/patchworkdir"
 
# host Python fails to import correct _sysconfigdata if this variable is set
_PYTHON_SYSCONFIGDATA_NAME[unexport] = "1"
 
 python() {
     tempdir = d.getVar('DEVTOOL_TEMPDIR')
