[分布式] Linux 下go build报错：cgo: exec gcc: exec: "gcc": executable file not found in

一、问题描述

~/Project/Distribute/mit2/src/main$ go build -buildmode=plugin ../mrapps/wc.go
# runtime/cgo
cgo: exec gcc: exec: "gcc": executable file not found in $PATH

提示没有 gcc可执行文件
看一眼版本号：

~/Project/Distribute/mit2/src/main$ gcc -v
Command 'gcc' not found, but can be installed with:
sudo apt install gcc

二、在Ubuntu上安装GCC

sudo apt update
sudo apt install build-essential

build-essential包含了 GNU 编辑器集合，GNU 调试器，和其他编译软件所必需的开发库和工具,包括gcc,g++,和make。

显示安装成功

再次执行go build任务，编译成功
