→Protocol Buffers with C Bindings

=== Protocol Buffers with C Bindings ===
CRIU uses the [http://code.google.com/p/protobuf-c/ C language bindings] of [http://code.google.com/p/protobuf/ Google Protocol Buffers] for serialization. The <code>protoc</code> tool is required at build time and <code>libprotobuf-c.so</code> is required at build time and at run time, assuming dynamic linking.

The easiest approach for most would be to install distribution packages. RPM package names: <code>protobuf-compiler</code>,<code>protobuf-c-devel</code>. Debian package names: <code>protobuf-compiler</code>, <code>libprotobuf-c0-dev</code>.
==== Building Protocol Buffers From Source ====
==== Building Protocol Buffers From Source ====
If you would like to build from source instead of using a package, the Protocol Buffer library can be found at http://code.google.com/p/protobuf/, while the Protocol Buffer C bindings can be found at http://code.google.com/p/protobuf-c/. You can use the following commands to obtain the source code repositories via <code>git</code>. Note that when cross compiling you will need to compile once for your build machine in order to get a <code>protoc</code> binary to use in the build process, and build once for each target machine to generate <code>libprotobuf-c.so</code>.
If you would like to build from source, you can use the following commands to obtain the source code repositories, configure, and build the code.
