On Ubuntu/Debian, you can install them with:

$ sudo apt-get install autoconf automake libtool curl make g++ unzip

You can also get the source by "git clone" our git repository. Make sure you have also cloned the submodules and generated the configure script (skip this if you are using a release .tar.gz or .zip package):

    git clone https://github.com/protocolbuffers/protobuf.git
    cd protobuf
    git submodule update --init --recursive
    ./autogen.sh

To build and install the C++ Protocol Buffer runtime and the Protocol Buffer compiler (protoc) execute the following:

     ./configure
     make
     make check
     sudo make install
     sudo ldconfig # refresh shared library cache.
