MTK开发环境搭建问题

[相门三少]

按手册搭建完毕，运行 ./mk check-env后，提示：
**********checking Env************
Please check your building environment First!

查看checkenvlog,提示：
[arm-linux-androideabi-gcc]: [FAIL]
you have not installed arm-linux-androideabi-gcc

检查了一下，发现arm-linux-androideabi-gcc是存在的，且PATH也是对的，哪位大神有遇到类似的问题，或谁能给点意见？
谢谢

使用arm-linux-androideabi-gcc -v命令看你所配置的环境变量是否生效
