lab-6.824

0. How to run?

go版本: 1.13+

• 在高于1.11的版本中报unexpected directory layout, 但是用较低版本goLand无法调试...
  • unexpected dir layout 原因是不支持相对路径包引入, 遇到时在import 删掉../即可

GoLand 准备

• 下载go 1.11.x

  

• 关闭go modules

  

1. Run Lab 1

命令行运行步骤:

$ cd src/main
$ go build -buildmode=plugin ../mrapps/wc.go
$ rm mr-out*
$ go run mrsequential.go wc.so pg*.txt
$ more mr-out-0

1. 准备build wc作为plugin (go build -buildmode=plugin ../mrapps/wc.go)

   建立src/main/build-wc.sh脚本:

   export GO111MODULE="auto"
   export GOROOT="/usr/local/go"
   export GOPATH="/Users/jinyuzhu/Documents/dev/mit_6824/lab-6.824"
   go build -buildmode=plugin ../mrapps/wc.go

   在idea run config中配置

   

2. 准备run mrsequential.go的配置

   

3. 执行go run mrsequential.go(idea中)

   

   • 如遇到../mr报错，则将../删掉即可

     import "../mr"
     // =>
     import "mr"

   • 调试与运行均正常
