i'm using Linux Mint. I've tried to install wxwidgets from repos, and done it, but when compiling standard code (from wxwidgets project template) got this warnings (and more):

The -Wunused-local-typedefs warning didn't exist (or at the very least wasn't enabled by default, I don't remember the details any more) when wxWidgets 2.8 was released 7.5 years ago. Please use wxWidgets 3.0.0 instead, it doesn't have these warnings and has tons of new features and bug fixes.
