These are two different problems. To detect real cause of the first one 
("Error launching builder") please try to launch make from command line 
having the project directory as a working irectory. If you see that make 
even no launched, validate your path.
Second issue is not a problem. After installation there is no selected 
default platform. To avoid this message in future, go to C/C++ 
preferences for new project and select your default platform(-s). For 
existing project do the same in the project properties.
