It may be due to your bleeding edge version of gcc, AFAIK nobody has tested compiling Geany with gcc-7.
The errors come from the [Scintilla](http://www.scintilla.org/) 3 editing component we use, which is C++ but uses only limited C++11 features to be able to support gcc 4.something. The next version of Scintilla 3 requires slightly more recent C++ features and is waiting for testing in #1504. Maybe you could try that. Scintilla 4 is in development and is intended to target gcc 7 (and use C++17 features) but its not yet released and may be API incompatible so it may be a while before it can be used by Geany (we will see when its released and Geany devs have gcc 7 available, we tend to be stuck in the mud stable distro users :). As for changing the error message, sorry thats a question you need to ask of the gcc developers, its not something we control, but it probably can't be improved much, it lists the missing functions and really can't do much else. -- You are receiving this because you are subscribed to this thread.
