#299 15.9 + master: build fails with gcc 10.2.1
gcc 10.2.1
Looks like C++ syntax is used in C files and even using g++ on failing file does not help.
It would be good to migrate git repo to github or gitlab to allow fetching exact commits patches over https/http.
BTW: Do you have any plans to make new nereleae?

AFAICS none of those failures actually originate in cscope itself.
Note how they're all in system library header files, which somehow expanded C++-only pieces to a C compiler. I would suspect the root cause to be either in a broken ncurses installation, or a broken RPM build script.
I'm using ncurses 6.2-4.2020081.
None of other my packages complains about anything wrong in ncurses header files.
Well, somehow it managed to hide the correct header file, curses.h, from the configure script. Instead it found the C++ version: cursesw.h. How exactly that happened can only be analyzed by looking at your config.log file. FWIW the original script would never even look for a file of that name.
Feel free to close that ticket.
I found what I've done wrong :P
It might be interesting to tell the public what that mistake was, so others can avoid tripping over it. I will close this anyway.
