I am able to compile with gcc but not from CodeLite GUI. The build tab is not highlighted so I can’t click any option.
When I open CodeLite it tells me that a new version is available. However, when I download the .deb and try to open it with Ubuntu Software Center it just hang indefinatly.
How to compile and run a code within CodeLite GUI when options are all grayed out?
Unlike Eclipse IDE you need to create a workspace first and a new project where you will have the actual source code of your project.
