•Go to Tools >> Options >> C++ and you will see the build tools panel. If NetBeans has not already found the standard build tools automatically, try clicking the "Restore Defaults" button. If this does not work, you will need to add them manually. To add the build tools, click the "Add..." button and then add the path to the bin folder—in which you can just activate C/C++ through Options—or you will have to install the C/C++ plugin with the NetBeans plugin manager
