Resolve mips-openwrt-linux-uclibc-g++.bin:environment variable "Staging_dir" not defined__linux

After OpenWrt compiles the tool chain and SDK, you may have the following error:

zchx@zchx-system-product-name:~$ mips-openwrt-linux-g++ mips-openwrt-linux-uclibc-g++.bin:environment Variable " Staging_dir "Not defined

The solution is simple, that is, compile the SDK also choose to compile, in the compiled SDK, including the tool chain. The tool chain here will not be an error. Good time.

Then add the Staging_dir to the environment variable.

Export staging_dir=~/downloads/openwrt-sdk-atheros-for-linux-i686-gcc-4.3.3+cs_uclibc-0.9.30.1/staging_dir/ Toolchain-mips_gcc-4.3.3+cs_uclibc-0.9.30.1/bin: $STAGING _dir
