然后使用 addr2line 进行查看错误地址的原代码位置

android::register_android_server_IRCtrlService(_JNIEnv*) at ??:0一般是文件路径没有加
文件路径不对
相对地址不对
总结（可以直接看这）find | grep | 使用前 查看筛选文件路径 | 在out目录下 find | grep 文件名 |
file | file 查看哪个文件才是需要的 (查找文件过程中会有很多路径不同但是文件名相同的，先根据路径排除一些，剩下的就是根据file) | file 文件路径 |
addr2line | addr2line 使用方法 | addr2line -C -f -p -i -e 报错文件路径 相对地址 |
