Yocto 無法交叉編譯 GoLang Wails 應用程式

问题内容

我正在使用 yocto kirkstone 为 armv7 定制嵌入式 linux 板构建系统。我的 yocto 元层中有 go-runtime 版本 1.20。

我正在尝试构建一个简单的示例 golang“wails”（https://github.com/wailsapp/wails）应用程序，我可以在 mac 上为我的目标构建该应用程序。这需要安装 wails 'cli' 来构建应用程序。我不知道如何与 yocto 交叉编译这个应用程序。我怎样才能做到这一点？谢谢。

此命令在 do_compile() 中失败：

wails build .

我收到的错误如下所示：

正确答案

我用下面的方法解决了这个问题。

    export GO111MODULE="on"
    export GOPATH="${WORKDIR}/build"
    export GIT_TERMINAL_PROMPT=1

    ${GO} install github.com/wailsapp/wails/v2/cmd/wails@latest

    /usr/bin/sync
    sleep 0.5

}

do_install() {
