when I try to build on codeblocks and I don't understand why

Question

I used to use dev c++ but now I decided to switch over to codeblocks. dev c++ worked normally but when I try to build on codeblocks nothing happens. I typed out some code compiled it and build it but when I tried to run it a message popped up saying I haven't build it yet and if I would like to build it now. when I clicked yes nothing happend and when I clicked no it would run but not work normally. some youtube videos recommended going to settings then compiler, selecting GNU GCC compiler, going to Toolchain executables and cliicking auto detect. in my case when I clicked auto detect a message saying could not auto-detect installation path of "GNU GCC Compiler". what should I do to fix these errors

Answer 1

install GCC then add its path to environment variable in path then click auto-detect again
if you're on windows

type environment variables in search box
click environment variables button in the dialog
in System Variables group double-click path(add one if missing)
click New then Browse buttons, naviagete to GCC folder
click Ok buttons to confirm, then back to code::blocks to auto-detect

or set the path to GCC manually in Toolchain executables tab
