你如何使-tags netgo成为默认值？ [英] How do you make -tags netgo the default for go?

问题描述

为了编译我的golang包以便产生一个静态链接的可执行文件，我必须说：

  go install -tags netgo 
  

另外我现在意识到在没有gcc的系统上，我必须：

  go get -tags netgo github.com/mypackage / ... 
 go test -tags netgo。/ ... 
  

如果你一直在输入这个数字，它就不那么好了。我设置了别名，这样我可以输入较少，但有没有一种更好或适当的方式来设置 - 将netgo标记为某种默认值？理想情况下，作为我的软件包本身的一部分，所以尝试使用我的软件包的陌生人不会错过-tags netgo。

编辑：我也希望有可能说：

  go install -tags netgo -ldflags'-linkmode external -extldflags -static -w'
  

即，链接到可以静态编译的C代码。所以它在没有GCC的机器上工作对我来说不那么重要，而不是产生静态链接的可执行文件。我只是想知道是否有办法做到后一种情况，而无需一直标记netgo。

您可以完全禁用cgo通过设置 CGO_ENABLED = 0 来防止net包连接到主机解析器。

To compile my golang package so that it produces a statically linked executable, I must say:

go install -tags netgo

Additionally I now realise that on a system without gcc, I must:

go get -tags netgo github.com/mypackage/...
go test -tags netgo ./...

If you're typing this all the time it's no so nice. I have aliases set up so I can type less, but is there a "nicer" or "proper" way to set -tags netgo as some kind of default? Ideally as part of my package itself, so a stranger trying to work with my package doesn't miss the -tags netgo.

Edit: I also want the possibility to say:

go install -tags netgo -ldflags '-linkmode external -extldflags -static -w'

Ie. link to C code that can be statically compiled. So it working on a machine without GCC is less important to me than it producing a statically linked executable. I just wonder if there's a way to do the latter without saying -tags netgo all the time.

解决方案

You can disable cgo altogether by setting CGO_ENABLED=0 which will prevent the net package from linking to the host resolver.
