GoReleaser交叉编译出错

来到golang学习网的大家，相信都是编程学习爱好者，希望在这里学习Golang相关编程知识。下面本篇文章就来带大家聊聊《GoReleaser交叉编译出错》，介绍一下，希望对大家的知识积累有所帮助，助力实战开发！

我试图在 linux 和 windwos 机器上发布我的项目，但没有成功。

我尝试将 -cc 显式定义为几个选项，但没有一个在两台机器上都有效。

预安装的软件包：

sudo apt-get install build-essential sudo apt-get install gcc-multilib g++-multilib sudo apt-get install gcc-mingw-w64

在项目中，我使用 c 代码，该代码使用这些 flags 进行选择性编译

//#cgo windows cflags: "-ic:/program files/openssl-win64/include"
//#cgo windows ldflags: "-lc:/program files/openssl-win64/lib" -llibcrypto
//#cgo linux ldflags: -lssl -lcrypto
//#cgo cflags: -wno-deprecated-declarations

在 windows 机器上本地运行 gorelaser 将导致此错误。

在 ubuntu 机器上本地运行 goreleaser 将产生结果

gcc: error: unrecognized command line option ‘-mthreads’; did you mean ‘-pthread’?

goreleaser：

正确答案

到 default，goreleaser 将尝试为 386、amd64 和 arm64 进行构建。但你的 windows 机器就像是 amd64/x86_64 机器。通常这对于 go 来说不是问题，但由于您使用的是 cgo，您的 c 工具链必须支持 arm64 的编译，但事实并非如此。

您应该能够通过将 goarch 添加到您的配置文件来限制它尝试构建的 cpu 架构：

...
builds:
  goarch:
    - amd64
...

交叉编译cgo项目是出了名的困难，goreleaser已知limitation。如果您还没有查看过 cgo cookbook，我建议您查看一下。

至于您在 ubuntu 上遇到的错误，看来您的 c 工具链没有正确的依赖项/功能来交叉编译到 windows。

我自己没有做过任何 cgo 交叉编译（不惜一切代价试图避免它），所以我不能保证这个工具，但从我在网上阅读的内容来看，xgo 可能可以帮助你。
