CodeLite IDE

Hello!
I'm a Mac User and I have downloaded Codelite for University. At the beginning it works wonderfully but now (I do not know what I have delete/change) I can't run anything: all the "Build" command are grey (impossible to click). (I will put a screenshot if only knew how).
Trying do something I have receive this popup "Failed to locate gdb at 'gdb' " and looking in some forums I've try to change something in Settings->Build Settings->Tools but no solution. Also I've try to delete and reinstall Codelite but doesn't work. Now I'm using Xcode but I want to solve this problem with Codelite.

If the tools are disabled ("grayed") it means that there is no workspace opened. Do you have a workspace open?
To take a screenshot, use CMD + SHIFT + 3 or CMD + SHIFT + 4 save it as PNG and attach it to the forum thread

Ok I finally solved this. I have to install Command Line Tool from Apple Developers sites. Thank you anyway for answering to my problem.

Note that you OSX, you should not use GDB as the debugger but rather select LLDB
This can be done from: Project settings->General->Debugger
