Getting the binder

The binder is installed by default on all redpesk distributions.

It is valuable to install the binder afb-binder, its simple client afb-client and the headers for developing bindings afb-binding on its development environment, because it allows two important things:

communication with redpesk services
first step debugging within a rich environment

Installing from packages

You can run the same command on a target runing a redpesk OS or in the SDK container (development mode).

dnf install afb-binder afb-client afb-binding-devel

Installing from rebuild

For older distributions that are not supported by IoT.bzh, or for less commonly used distributions (gentoo, arch, …) it is possible to build from sources.

Building from sources is done in 4 steps:

install required dependencies
clone source repositories
setup environment
compile and install sources

Install dependencies

When developing inside the SDK container, to install the build dependencies, run the following command:

dnf builddep afb-binder

Get the sources

Building the binder and the client from the sources requires cloning of the following repositories:

afb-binding: https://github.com/redpesk-core/afb-binding
afb-libafb: https://github.com/redpesk-core/afb-libafb
afb-binder: https://github.com/redpesk-core/afb-binder
afb-client: https://github.com/redpesk-core/afb-client

It can be achieved as below:

git clone https://github.com/redpesk-core/afb-binding.git
git clone https://github.com/redpesk-core/afb-libafb.git
git clone https://github.com/redpesk-core/afb-binder.git
git clone https://github.com/redpesk-core/afb-client.git

Compile and install

Before compiling you have to choose the base directory where you want to install the programs and development files. That directory is noted PREFIX. The common values of PREFIX are:

/usr
/usr/local
$HOME/.local

The two first require to have privilege (as user root), the latter doesn’t.

Then to compile the whole set, enter the following commands:

export PREFIX=$HOME/.local
export CPATH=$PREFIX/include:$CPATH
export LD_LIBRARY_PATH=$PREFIX/lib64:$PREFIX/lib:$LD_LIBRARY_PATH
export LD_RUN_PATH=$PREFIX/lib64:$PREFIX/lib:$LD_RUN_PATH
export LIBRARY_PATH=$PREFIX/lib64:$PREFIX/lib:$LIBRARY_PATH
export PATH=$PREFIX/bin:$PATH
export PKG_CONFIG_PATH=$PREFIX/lib64/pkgconfig:$PREFIX/lib/pkgconfig:$PKG_CONFIG_PATH

afb-binding/mkbuild.sh install
WITHOUT_CYNAGORA=ON afb-libafb/mkbuild.sh install
afb-binder/mkbuild.sh install
afb-client/mkbuild.sh install

It is done!
