linux - 为交叉编译设置 Go 时出错

Question

我正在使用 64 位 Linux，我正在尝试设置 Go 以进行交叉编译(特别是针对 Windows)。有一个很棒的指南 here .但是当我尝试运行下面的第二个命令时:

cd /usr/lib/go/src
sudo GOOS=windows GOARCH=386 CGO_ENABLED=0 ./make.bash --no-clean

当它尝试构建 cmd 包时出现错误。它说不允许使用内部包。这是 Go 主要源代码中的错误吗？我将粘贴完整的错误列表。

我在 Google 上找不到类似的东西，所以这可能意味着我做错了什么。顺便说一下，我使用的是 Arch Linux，并且我使用 pacman 安装了 Go，而不是从源代码安装的。

这个错误来自cmd/go/pkg.go#L358 , 并查看 blame View 表明这已由 commit 1338f32 介绍去 1.4

因此该指南可能仅适用于 go 1.3-，不适用于 go 1.4，因为 Go 1.4 "Internal" Package proposition .

For Go 1.4, we will implement the rule first for $GOROOT, but not $GOPATH. We will use the compiler conversion and some minor uses in the standard library to gain experience with the rule.

Due to an irregularity in the main repo, as a special case, the “/pkg/” element in $GOROOT/src/pkg/… paths is considered not to exist.
This means that $GOROOT/src/pkg/internal can be imported by $GOROOT/src/cmd/… in addition to $GOROOT/src/pkg/….
This special case will be removed when we move the standard library up to $GOROOT/src/.
