The Cppcheck website tells me that Code::Blocks has Cppcheck built in. The Wikipedia page on IDEs tells me that Code::Blocks has an integrated static code analysis (that would be Cppcheck then, wouldn't it?).
Where can I find it? Looked through all menus and plugins and documentation that I could find, but nothing....
It's possible you opted-out of the plugins when you were first installing Code::Blocks. If this is the case, you might need to install it manually.
Under the "Plugins" menu, go to "Manage plugins..." and select "Install new." The plugin file is available here: http://www.2shared.com/file/-EZxdUJG/CppCheck-11.htm
