我是物联网的新手，我想为arm64 linux设备交叉编译它.我正在研究Ubuntu 14.04 LTS(x86_64(。我有ARM设备的工具链，我尝试了以下代码：
scons TARGET_ARCH=arm TARGET_OS=linux TC_PREFIX=/home/toolchain_folder/arm-linux-gnueabihf/bin
我收到这些错误：
************************************ Warning **********************************
* Enviornment variable TC_PREFIX/TC_PATH is set. It will change the default *
* toolchain, if it isn't what you expect you should unset it, otherwise it may*
* cause inexplicable errors. *
