C/C++ option not available in NetBeans

Solution 1:

The answer provided by https://askubuntu.com/users/22949/eliah-kagan did not work for Ubuntu 19.04 with NetBeans 11 since the C++ plugin is not available under "Netbeans Distribution" when I tried it.

To install C++, I also had to select the Update Center labeled "NetBeans 8.2 Plugin Portal". It appears that C++ is not in the latest distribution yet, so I had add the legacy Update Center.

After adding this update center, I was able to locate and install the C++ plugin as shown in the previous answer, and then create a C++ HelloWorld program in NetBeans 11 on Ubuntu 19.04

Solution 2:

Install the C/C++ plugin in NetBeans.

In NetBeans, go to Tools → Plugins.

Then in Available Plugins, in the C/C++ category, check the box for C/C++, then click Install to start the installation.

If no update centers are enabled in NetBeans for installing and updating plugins, then you may see a completely empty list under Available Plugins. (Less commonly, if some are enabled but they do not provide the C/C++ plugin, then you may see some plugins but not that one.)

The solution is to go to the Settings tab, look in the list of Update Centers, and check the box for NetBeans Distribution.

Then you can go back to the Available Plugins tab and the C/C++ plugin should be listed. You may have to click the Check for Newest button (though I didn't have to).
