→‎Protocol Buffers with C Bindings

Line 18: Line 18:

=== 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.

==== Distribution Packages ====

−

~~CRIU uses the C bindings of Google's Protocol Buffers.~~ The easiest approach for most would be to install a distribution packages. RPM package ~~name~~: <code>protobuf-c-devel</code>. Debian package ~~name~~: <code>libprotobuf-c0-dev</code>.

+

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 ====

−

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.

+

mkdir deps

+

cd deps

git svn clone http://protobuf.googlecode.com/svn/trunk protobuf

cd protobuf

./autogen.sh

−

./configure --prefix=`pwd`/`uname -m`

+

./configure --prefix=`pwd`/../`uname -m`

make

make install

−

cd ..

+

cd ../..

−

~~If you are cross compiling, then you will additionally want to build a version for your target architecture. This example targets AArch64.~~

−

~~cd protobuf~~

−

./~~configure --host=aarch64-linux-gnu --prefix=`pwd`/aarch64 --with-protoc=`pwd`/`uname -m`/bin/protoc~~

−

~~make~~

−

~~make install~~

−

cd ..

+

cd deps

git svn clone http://protobuf-c.googlecode.com/svn/trunk protobuf-c

cd protobuf-c

−

./autogen.sh

+

./autogen.sh --prefix=`pwd`/../`uname -m` --disable-protoc

−

~~./configure~~ --prefix=~~`pwd`/`uname -m` PATH="~~`pwd`/..~~/protobuf~~/`uname -m`~~/bin:$PATH"~~

make

make install
