我正在尝试在 Raspberry Pi 2 上构建 IoTivity 框架，该框架具有 arm 架构并在 Ubuntu Mate 15.04 上运行。我继续在 linux 上构建 IoTivity 的官方指南（Linux：入门）。主要问题是当我想使用 scons 命令构建 IoTivity 时：
scons TARGET_OS=linux TARGET_ARCH=arm
终端输出：
filip@fiip:~/iotivity$ scons TARGET_OS=linux TARGET_ARCH=arm
scons: Reading SConscript files ...

我知道我需要安装 arm gcc 和 g++ 编译器，所以我安装了arm-linux-gnueabihf-gcc-4.8和 arm-linux-gnueabihf-g++-4.8并根据 这个建议更新了 project-config.jam。
我尝试了本教程 ，但没有成功。我做错了什么 ？我很乐意提供任何建议，指导如何在 armv7 架构上构建 IoTivity 框架。谢谢。
