CRIU is mostly written in C and the build system is based on Makefiles. Thus just install standard <code>gcc</code> and <code>make</code> sets.
CRIU is mostly written in C and the build system is based on Makefiles. Thus just install standard <code>gcc</code> and <code>make</code> packages (on Debian, <code>[https://packages.debian.org/build-essential build-essential]</code> will pull in both at once).
If you are cross compiling for ARM, use distribution packages or download prebuilt toolchains from Linaro.

=== Protocol Buffers ===
=== Protocol Buffers ===
CRIU uses the [https://developers.google.com/protocol-buffers/ Google Protocol Buffers] to read and write [[images]] and thus requires [https://github.com/protobuf-c/protobuf-c C language bindings]. The <code>protoc</code> tool is required at build time and the <code>libprotobuf-c.so</code> is required at build and run time. [[CRIT]] also uses python language bindings for protocol buffers and requires the <code>descriptor.proto</code> file from devel set that can be typically found in the <code>protobuf-devel</code> package.

The <code>protoc</code> tool is required at build time and the <code>libprotobuf-c.so</code> shared object is required at build and run time. [[CRIT]] also uses python language bindings for protocol buffers and requires the <code>descriptor.proto</code> file typically provided by a distribution's protobuf development package.

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. On a Debian based system, you may have to do <code>autoconf curl g++ libtool</code> first.
