make[1]: nds32le-elf-g++: Command not found

../scripts/rules.mk:105: recipe for target 'firmware' failed

make[1]: *** [firmware] Error 127

Makefile:181: recipe for target 'st' failed

make: *** [st] Error 2

原因，没有添加编译链环境变量

export  PATH=/usr/local/bin/nds32le-elf-mculib-v3/bin/:$PATH

添加永久环境变量：

​vi /etc/profile​ 

t添加

export  PATH=/usr/local/bin/nds32le-elf-mculib-v3/bin/:$PATH

保存，然后source刷新刚才保存的。

source ​vi /etc/profile​
