Go编译为windows/arm和arm64，使用buildmode=c-shared

Golang小白一枚，正在不断学习积累知识，现将学习到的知识记录一下，也是将我的所得分享给大家！而今天这篇文章《Go编译为windows/arm和arm64，使用buildmode=c-shared》带大家来了解一下##content_title##，希望对大家的知识积累有所帮助，从而弥补自己的不足，助力实战开发！

我需要通过 c 将 go 库编译为可以通过 arm/arm64 windows 上的 pinvoke 使用的 dll。我发现了许多与此相关的悬而未决的问题、主题和讨论，听起来它可能部分有效。但如果我尝试这样：

export cc="arm-none-eabi-gcc"
    export cxx="arm-none-eabi-g++"
    export goos="windows"
    export goarch="arm"
    export goarm=7
    export cgo_enabled="1"
    go build -ldflags="-s -w" -o my_library.dll -buildmode c-shared

我得到的结果是 windows/arm 不支持 buildmode c-shares。所以好像还是不支持。

另一个问题是我需要设置 cgo_enabled 并通过 c/c++ 工具链进行编译，因为我必须添加由 swig 生成的 c 文件。我在 ubunu 20.04 上使用 gcc-arm-none-eabi 包的工具链尝试了上述操作。

我不是 c/c++/go 专业人士 - 但同样适用于几乎所有其他平台，如 windows、linux、android、mac 和 ios。后者也是基于 arm64 的，所以我不太明白为什么这是不可能的 - 尽管我很重视这一切的困难。

所以，如果有更深入知识的人可以帮助我，那就太好了。

澄清一下：我不想/不需要为 arm/arm64 编译 go 本身。我需要为该平台编译一个 go 程序（以便在 surface 或 hololens 等上使用 .net 中的库）。

自 2021 年 8 月 4 日更新：

go 1.17rc2 现在应该包含 windows arm64。我得到了使用 zig 进行交叉编译的提示。因此，我将构建管道更改为如下所示（我在 ubuntu vm 中使用 azure devops）：

go get -v golang.org/dl/go1.17rc2
/home/vsts/go/bin/go1.17rc2 download
/home/vsts/go/bin/go1.17rc2 version
sudo snap install zig --classic --beta
zig version
export cc="zig cc -target aarch64-windows-gnu"
export cxx="zig c++ -target aarch64-windows-gnu"
export goos="windows"
export goarch="arm64"
export goarm=7
export cgo_enabled="1"
/home/vsts/go/bin/go1.17rc2 build -ldflags="-s -w" -o storj_uplink.dll -buildmode c-shared -tags extended

然后我收到此错误：

基本上是“未知命令：-e”，此处描述。但根据我的理解，这应该已经有效了。此外，这篇博文也直接使用 zig 来实现。

2021 年 8 月 4 日第二次更新

go 现在正在调用 zig！使用 bash 脚本的解决方法有效。现在我收到以下错误：

自 2021 年 8 月 5 日更新：

我终于找到了一个至少不会抛出错误的工具链。但现在它静静地退出，不生成 dll。但不确定现在会发生什么。这是我的电话：

解决方案

应该可以，使用 Go 1.17 beta

Its documentation 请提及：

OP topperdel 指的是 the comments 到 CL 326310：

正如这些问题所示，这仍然是一项正在进行的工作：

• issue 46502（“runtime：由于重新声明警告（升级为测试中的错误），windows-arm64-aws 构建器上的多项测试失败”），
• issue 46701（“arm64/arm 上的 Powershell 无法加载 arm64/arm 二进制文件，因为它是英特尔进程”）

测试部分现已（2021 年 6 月 13 日）结束，编号为 golang/go commit 1ed0d12：

我在the comments中提到

从 ziglang/zig issue 7342 开始，现在应该支持 zig。
以 Go 1.17 为例：来自 Loris Cro 的“Zig Makes Go Cross Compilation Just Work”（社区副总裁 @ziglang）：

您需要根据您的需要调整架构目标

注意：需要 bash shell 会话。例如，Windows 上的 git bash。
