If you set the environment variables CC and CXX to executables for a working C and C++ compiler, respectively, and retrigger CMake configuration (by using --force-cmake-config or by deleting the packages you want to be affected), CMake will reconfigure and use the different compiler. Having one or more plain ROS nodes in a process doesnt add new standardized ways to get information into or out of the operating system process that contains them, though ROS topics, services, parameters, etc. If you set the environment variables CC and CXX to executables for a working C and C++ compiler, respectively, and retrigger CMake configuration (by using --force-cmake-config or by deleting the packages you want to be affected), CMake will reconfigure and use the different compiler.

The goal of the ROS 2 project is to adapt to these changes, leveraging what is great about ROS 1 and improving what isnt. Any operating system process can become ROS specific by having at least one ROS Node within it. Creating Time and Duration Instances. When using simulated Clock time, now() returns time 0 until first message has been received on /clock, so 0 means essentially that the client does not know clock time yet. matlab mex SDK Each parameter is specific to a node.
