Go program not statically linked using 1.4.2
问题
尝试构建一个静态链接版本的Go程序，该程序运行一个HTTP服务器，并使用net包来确定和解析传入请求的IP地址。使用以下构建语句：
CGO_ENABLED=0 go install -a -ldflags '-s' .
并在我的程序中添加以下前言：
package main
import (
"encoding/json"
"errors"
"fmt"
"log"
"net"
"net/http"
"path/filepath"
"strings"
"golang.org/x/blog/content/context/userip"
"github.com/oschwald/maxminddb-golang"
)
这在使用Go 1.3构建时有效，可以生成一个静态链接的程序，但在使用Go 1.4.2时无效。构建成功，但程序没有静态链接。
有人知道发生了什么吗？
英文:
Trying to build a statically linked version of a go program that runs an http server, and uses the net package to determine and parse the IP address of the incoming request. With this build statement:
CGO_ENABLED=0 go install -a -ldflags '-s' .
And this preamble in my program:
<!-- language: lang-go -->
package main
import (
"encoding/json"
"errors"
"fmt"
"log"
"net"
"net/http"
"path/filepath"
"strings"
"golang.org/x/blog/content/context/userip"
"github.com/oschwald/maxminddb-golang"
)
This worked building with go 1.3, producing a statically linked program, but is not working with go 1.4.2. The build succeeds, but the program is not statically linked.
Does anyone know what is going on?

更多的搜索发现了关于无法静态链接导入net包的程序的问题的这个golang问题跟踪器中的线程，原因是1.3和1.4之间的更改。
往下阅读，我发现ianlancetaylor建议的这个解决方法，使用-installsuffix开关来指定cgo。这使得我的构建语句变为：
CGO_ENABLED=0 go install -a -installsuffix cgo -ldflags '-s' .
这对我起作用。构建成功并生成了一个静态链接的程序。

More searching turned up this thread in the golang issue tracker about being unable to statically link a program that imports the net package due to changes between 1.3 and 1.4.
Reading down I found this workaround suggested by ianlancetaylor to use the -installsuffix switch to specify cgo. This made my build statement:
CGO_ENABLED=0 go install -a -installsuffix cgo -ldflags '-s' .
Which worked for me. Build succeeded and produced a statically linked program.
