linux export env

$find /opt/toolchains/ -type l -name mipsel-linux-gcc
/opt/toolchains/stbgcc-4.5.3-2.4/bin/mipsel-linux-gcc

$dirname $(find /opt/toolchains/ -type l -name mipsel-linux-gcc)
/opt/toolchains/stbgcc-4.5.3-2.4/bin

 

 

必須把toolchain加到環境變數的PATH中
export PATH="/opt/toolchains/stbgcc-4.5.3-2.4/bin:$PATH"

or
export PATH=$PATH:/opt/toolchains/stbgcc-4.5.3-2.4/bin
