gomobile 编译

背景

接触go之后，编译了一个用go写的项目，准备编译成aar，在Android 工程中使用。
这里记录下，编译时候遇到的问题，方便后续排查遇到的一样问题。

使用的编译命令：
当前路径： $GOPATH/src/

 $ gomobile bind -target=android/arm64 -o out/diagnotic.aar diagnotic/

问题

• 编译找不到依赖的相关库

gomobile: go build -buildmode=c-shared -o=/var/folders/_g/m69td9r963bbq1rb4pjt2v340000gn/T/gomobile-work-664583801/android/src/main/jniLibs/arm64-v8a/libgojni.so ./gobind failed: exit status 1

解决方案：

1、 github 中，寻找到对应的开源库， 下载到 $GOPATH/src/ 目录下。
