使用CCache加快Linux平台編譯速度

 Using "Ccache" to improve compiler time

1. Install "Ccache"

2. Create a path for compiler

    ls /usr/lib/ccache

    mkdir /usr/lib/ccache

    pushd . //keep current path

    cd /usr/lib/ccache

    sudo ln -s ../../bin/ccache arm-marvell-linux-gnueabi-gcc

    sudo ln -s ../../bin/ccache arm-marvell-linux-gnueabi-g++

    sudo ln -s ../../bin/ccache arm-marvell-linux-gnueabi-cc

    sudo ln -s ../../bin/ccache arm-marvell-linux-gnueabi-c++

    popd //return pushd . keep current path

3. Put "Ccache" search path into $PATH 

    export PATH=/usr/lib/ccache:$PATH

4. Keep $PATH always

    vi ~/.profile

    ==>export PATH=/usr/lib/ccache:$PATH

5. Reopen connection and check $PATH

    echo $PATH
