1. debug by gdb:html

 download the runtime-gdb file.git

$ wget -q -O - https://golang.org/src/runtime/runtime-gdb.py  |grep '<span id="L' >  runtime-gdb.pygithub

$ sed -i -e "s/<span.*span>//g" -e "s/<pre>//g" -e "s/^\t//g" -e 's/&#34;/"/g' -e "s/&#39;/'/g" -e "s/&gt;/>/g" -e "s/&lt;/</g" -e "s/amp;//g" runtime-gdb.py bash

linux 下应该有脱字符处理工具(iconv)。　或者wget 自己应该能处理掉脱字符。ide

 

run gdb by: 工具

$ $GOROOT=`go env  |grep GOROOT |cut -d "=" -f2`ui

$ gdb your_bin -d $GOROOTidea

$ gdb cpuinfo_main -d `go env  |grep GOROOT |cut -d "=" -f2`

source ~/go/src/runtime/runtime-gdb.py

 发现最新的golang1.6已经自带了runtime-gdb.py

进入gdb

(gdb) add-auto-load-safe-path /usr/local/go/src/runtime/runtime-gdb.py

echo "set auto-load safe-path /" > line to your configuration file "/home/shaohef//.gdbinit".

直接运行

$ gdb your_bin 

２．　godebug

Download:

$ go get -u github.com/mailgun/godebug

将　_ = "breakpoint"　插入代码。

build godbug

$ go build 

mv  godbug to goroot bin

$ sudo cp godebug /usr/local/go/bin/

$ debug

godbug run your go_file.

3.  Go语言debug调试

4. 采用idea IDE环境。

5. 使用Delve进行Golang代码的调试

使用Delve调试test case

dlv test --build-flags='github.com/dlsniper/u/tmp/mypack' -- -test.run ^TestHello$
