ManjaroKDE安装Yocto eSDK

前提

Manjaro版本：5.3.8-3
yocto版本：2.6.1（thud）
使用crops/yocto编译出eSDK后想要安装到ManjaroKDE

安装依赖

OpenEmbedded requires 'python' to be python v2 (>= 2.7.3), not python v3.

当报以上错误时需要执行sudo pacman -S python2安装python2。

当报以上错误时使用使用ls -al /your/path/to/build/tmp/hosttools查看缺少哪些包（缺少的包底色不一样）如 下图中的rpcgen：

rpcgen

我这里缺少chrpath pod2man rpcgen，对应的包分别是chrpath perl rpcsvc-proto。
安装完perl后需要使用sudo ln -S /usr/bin/core_perl/pod2man /usr/bin/pod2man进行软链接，使用where pod2man可知pod2man路径是否符合hosttools内的路径。
另外sudo比较特别，需然底色不一样但路径是对的，系统自带不用管。
之后正常安装eSDK即可。
