When we usually open the JUCE Code Interface, we will only be able to find the default Exporters only. (XCode, Visual Studio 2017, Linux Makefile).
To add the New Exporter Target, under the Exporters, click the add button and and select for the Code Block (Linux).
After the item has been added you will get an entry for - Code Block (Linux).
Once that is done, save the project from JUCE.
After that go to the corresponding folder where the file is saved.
Under the corresponding project folder, Browser for folder Build and then for folder - Code Block. Then open the .cbp file and the project will get successfully launched in Code Block IDE. Then we can build and run the program.
