编译ngrok的Windows、Mac的客户端

234cfds1

　　ngrok是一个ddns服务，为内网机器绑定一个公网域名，方便开发调试远程接口(如微信开发)。
　　之前博文里面写过如何安装ngrok，但是由于公司里面的研发工程师的笔记本有windows本和mac本，所以本次主要讲怎么生成windows、mac客户端。
　　准备工作：需要参考http://nanchunle.blog.51cto.com/9244770/1710295，安装完成ngrok
　　一、编译Windwos客户端
cd /usr/local/go/src　　GOOS=windows GOARCH=amd64 ./make.bash
　　cd /usr/local/ngrok
　　GOOS=windows GOARCH=amd64 make release-client
　　#同理，这里的amd64是64位系统，32位改成386
　　#应该会在 bin/windows_amd64 目录下生成ngrok客户端程序

　　到这里，编译就完成了，就可以将ngrok.exe下载到windows操作系统。
　　启动步骤：
　　1、将ngrok.exe放在D:\ngrok，并且在D:\ngrok编辑配置文件ngrok.cfg
server_addr: "example.com:4443"　　trust_host_root_certs: false
2.打开windows控制台win+r ,进入D:\ngrok，执行./ngrok -config=ngrok.cfg -log=ngrok.log -subdomain=test 8080　　二、编译Mac客户端
　　cd /usr/local/go/src
　　GOOS=darwin GOARCH=amd64 ./make.bash
　　然后回去ngrok目录，接着编译：
　　cd /usr/local/src/ngrok

　　GOOS=darwin GOARCH=amd64 make>　　完成后会在 /usr/local/src/ngrok/bin/darwin_amd64/ 下发现 ngrok 文件，将其拷贝到Mac上面，像上面windows
　　的设置即可使用。
　　三、注意事项
　　1、Centos/Linux下源码安装golang：

• 　　wget https://storage.googleapis.com/golang/go1.4.1.linux-amd64.tar.gz
  
• 　　tar -C /usr/local -xzf go1.4.1.linux-amd64.tar.gz
  
• 　　mkdir $HOME/go
  
• 　　echo 'export GOROOT=/usr/local/go' >> ~/.bashrc
  
• 　　echo 'export GOPATH=$HOME/go' >> ~/.bashrc
  
• 　　echo 'export PATH=$PATH:$GOROOT/bin:$GOPATH/bin' >> ~/.bashrc
  
• 　　source $HOME/.bashrc
  

　　2、在步骤GOOS=darwin GOARCH=amd64 make>　　imports runtime: C source files not allowed when not using cgo or SWIG: atomic_amd64x.c defs.c float.c heapdump.c lfstack.c malloc.c mcache.c mcentral.c mem_darwin.c mfixalloc.c mgc0.c mheap.c msize.c os_darwin.c panic.c parfor.c proc.c runtime.c signal.c signal_amd64x.c signal_unix.c stack.c string.c sys_x86.c
　　make: *** [deps] Error 1

Introduction
　　This is a companion to http://golang.org/doc/install/source providing additional instructions for various operating systems.
Install C tools
　　On OS X, a C compiler is bundled in the command line tools for Xcode, and you don't need to install the whole Xcode to compile Go. If you have already installed Xcode 4.3+, you can install command line tools from the Components tab of the Downloads preferences panel. In more recent versions of Xcode, you can use xcode-select --install command to install the command line tools without opening Xcode. To verify you have a working compiler, just invoke gcc in a freshly created Terminal window, unless you see the "gcc: command not found" error, you are ready to go.
　　On Ubuntu/Debian, use sudo apt-get install gcc libc6-dev. If you want to build 32-bit binaries on a 64-bit system you'll also need the libc6-dev-i386 package.
　　On RedHat/Centos 6, use sudo yum install gcc glibc-devel. If you want to build 32-bit binaries on a 64-bit system you'll need both glibc-devel.i386 and glibc-devel.x86_64 packages.
　　On Windows, install gcc with TDM-GCC. (Make sure you add its bin subdirectory to your PATH.) Go does not support the Cygwin toolchain.
