编译运行时无法禁用优化

When I use VSCODE in my Ubuntu 16.10 to compile my go project, it can't succeed and prompt:

compile: cannot disable optimizations while compiling runtime
exit status 2
Process exiting with code: 1

I checked my launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch",
            "type": "go",
            "request": "launch",
            "mode": "debug",
            "remotePath": "",
            "port": 2345,
            "host": "127.0.0.1",
            "program": "${fileDirname}",
            "env": {
                "GOPATH":"/home/bill/test/go",
                "GOROOT":"/usr/local/go"
            },
            "args": [],
            "showLog": true
        }
    ]
}

What can I do to change this?

This error message seems to come from the Go compiler due to this change which fixes this bug (the "compile: " prefix is apparently added by vscode).

My take on the reason is as follows:

1. You have Go runtime source code somehow modified since before you started to experience the present problem.
2. An attempt to build your program detects the runtime has changed and needs to be rebuilt as well—simply because parts of it are included into any program built with Go.

As to how to solve this, I have no clean idea. Supposedly running

$ cd /usr/local/go/src
$ ./make.bash

should do it.

On a side note, you must not set the GOROOT env. variable by hand—please leave it to the Go suite instead; since many versions ago, it knows its GOROOT automatically based on where the go binary is located.
