Can'；t使用CGO AMD与Xgo交叉编译Go项目=>；手臂

我正在做一个go项目，它实现了C代码

我可以在linux/amd64上构建这个项目，现在如果我们使用“IMPORT C”，就不会交叉编译。 因此，我与XGO合作，这可能有助于我交叉编译ARM

我在没有C代码的情况下，通过交叉编译我的go项目版本来检查XGO，它的工作方式与go的交叉编译类似

我的环境：

go version go1.13.3 linux/amd64

Go env:

GO111MODULE="on"
GOARCH="amd64"
GOBIN="/opt/go/bin"
GOCACHE="/home/jj/.cache/go-build"
GOENV="/home/jj/.config/go/env"

GOMOD="/opt/go/src/github.com/brocaar/lora-app-server/go.mod"

CGO_CPPFLAGS=""

我的项目正在进行中=>

/opt/go/src/github.com/brocaar

我的包含c代码的包已打开=>

/opt/go/src/github.com/lorawan

我的项目的go.mode：

  module github.com/brocaar/lora-app-server

  go 1.12

  replace github.com/brocaar/lorawan => /opt/go/src/github.com/brocaar/lorawan

  require (

         )

src/github.com/brocaar/lora-app-server/cmd/lora-app-server

我的交叉编译命令是：

xgo -go 1.13.3  --targets=linux/arm-7 /opt/go/src/github.com/brocaar/lora-app-server/cmd/lora-app-server

结果错误为：

  module github.com/brocaar/lora-app-server

  go 1.12

  replace github.com/brocaar/lorawan => /opt/go/src/github.com/brocaar/lorawan

我现在真的不明白他为什么说“没有这样的文件或目录”，因为lorawan文件夹中有go.mod！有人能帮我吗？谢谢

我终于找到了解决办法

首先我在ubuntu arm linux gnueabi gcc上安装，然后我只是在交叉编译命令CC中添加如下内容：

env GOOS=linux GOARCH=arm GOARM=7 CGO_ENABLED=1 CC=arm-linux-gnueabi-gcc  go build

很好

检查是否有正确的go.mod文件directory@cslrnr我检查了一下，在/lorawan中有一个go.mod，编译器会找到这个存储库，所以。。。
