Cumulocity C++ Library

Cumulocity C++ Library is an asynchronous, event-driven networking library to ease your development for connecting to the Cumulocity cloud. The library uses Cumulocity's self invented SmartREST protocol for M2M communication which targets any device that are capable of running embedded Linux.

Prerequisites

• C++ 11
• Linux >= 2.6.32
• libcurl >= 7.26.0
• Lua >= 5.0 (optional, for Lua support)

How to build the library?

• Download the source code:

#!bash

git clone git@bitbucket.org:m2m/cumulocity-sdk-c.git

• Pull in all sub-module dependencies.

#!bash
git submodule init
git submodule update

• Define your init.mk with device specific CPPFLAGS, CXXFLAGS, LDFLAGS, LDLIBS (see common.mk for reference), and CXX if cross compiling.
• Copy the template Makefile:

#!bash

cp Makefile.template Makefile

• Customize the Makefile to your needs.
• Build the library in debug mode:

#!bash

make

• Starts developing your Cumulocity agent and link it to the library with -lsera.
• Build the library in release mode for production release:

#!bash

make release

FAQ

• I encountered an error when building the library.
  Try removing all intermediate build files first and start a new clean build:

#!bash

make clean

• How can I enable Lua support when building the library?
  Lua support is disabled by default, to enable Lua support, add:

#!bash

SR_PLUGIN_LUA:=1

to your init.mk.
