Question

我正在尝试使用基于arm64的“ amd64”为“ arm64”架构构建go代码。使用共享库构建go代码时，出现以下错误。有人可以帮我吗？

转到版本： go1.10.3 linux / amd64

gcc版本： gcc版本7.3.0（Ubuntu 7.3.0-21ubuntu1〜16.04）

转到环境：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div style="background:black; width:100px; height:100px; padding:20px;">
  <p style="color:white;">on/off button:</p>
  <label class="switch">
    <input name="saveee" type="checkbox">
    <span class="slider round"></span>
  </label>
</div>

错误：去建立hello.go

GOARCH="arm64"
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
CGO_ENABLED="1"

Answer 1

我像这样#cgo LDFLAGS链接了数学库：-L./cgolang/lib -lpthread -lm

对我有用。如果您的共享库是由第三方提供的，请让他们帮助您

Answer 2

env CGO_ENABLED=1 GOOS=linux GOARCH=arm64 CC=/path/to/your/arm64/gcc go build hello.go

您可能会看到同样的问题：https://github.com/golang/go/issues/8161

cgo从amd64（linux）交叉编译到arm64（linux）
