## Installation of Protobuf-c

First fix issues caused by Protobuf-34.1 and later:

    patch -Np1 -i ../protobuf-c-1.5.2-protobuf34_fix-1.patch

Install Protobuf-c by running the following commands:

    ./configure --prefix=/usr --disable-static &&
    make

To test the results, issue: make check.

Now, as the `root` user:

    make install

## Command Explanations

`--disable-static`: This switch prevents installation of static versions of the libraries.

## Contents

Installed Programs: protoc-gen-c and protoc-c (symlinked to protoc-gen-c)
