RK3399Linuxsdk开发--buildroot编译错误问题集锦

1. 使用 build.sh rootfs 编译rootfs出现如下问题

You seem to have the current working directory in your
PATH environment variable. This doesn't work.
support/dependencies/dependencies.mk:25: recipe for target 'core-dependencies' failed
make[1]: *** [core-dependencies] Error 1

解决办法：ubuntu下使用su指令切换到root用户，root用户编译：build.sh rootfs ，编译通过后再切换到普通用户编译即可通过……不明就里……
