去安装创建目录os_arch-选择不同的输出目录

Question

I have this folder structure for my fib package:

$ tree 
.
└── src
    └── fib
        ├── fib
        │   └── main.go
        ├── fib.go
        └── fib_test.go

(main.go is in package main, fib(_test).go is in package fib)

GOPATH is set to $PWD/src, GOBIN is set to $PWD/bin. When I run go install fib/fib, I get a file called fib in the directory bin (this is what I expect):

$ tree bin/
bin/
└── fib

But when I set GOOS or GOARCH, the directory in the form GOOS_GOARCH is created:

$ GOARCH=386 GOOS=windows go install fib/fib
$ tree bin/
bin/
└── windows_386
    └── fib.exe

This is not what I want. I'd like to have the file fib.exe in the bin directory, not in the sub directory bin/windows_386.

(How) is this possible?

Answer 1

That doesn't seem possible, as illustrated in issue 6201.

GOARCH sets the kind of binary to build.
You might be cross-compiling: GOARCH might be arm.
You definitely don't want to run the arm tool on an x86 system.
The host system type is GOHOSTARCH.

To install the api tool (or any tools) you need to use

GOARCH=$(go env GOHOSTARCH) go install .../api

and then plain 'go tool' will find them.

In any case (GOARCH or GOHOSTARCH), the go command will install in a fixed location that you cannot change.
