安装的gcc-linaro-6.3.1-2017.02-x86_64_arm-linux-gnueabihf，gcc 没问题。g++提示找不到。百度了一大圈也没搞定。哪位指点一下。谢谢。

换一个最新版本
gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabihf ，换了这个最新的版本还是这样。要崩溃了。晕哥你能编译cpp吗?

我安装在opt 下，我find 也有啊
sinlinx@ubuntu://opt$ find . |grep linaro |grep g++$
./gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++
./gcc-linaro-6.3.1-2017.02-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++
但是编译arm-linux-gnueabihf-g++ 编译一个最简单的hello就提示找不到arm-linux-gnueabihf-g++ .

gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabihf 好像也用不了。
是编译CPP 文件是吧。
