Hmm, this must be a stricter warning set in newer versions of GCC. I had a quick look at the code, and I think it's not an actual error in this case. The quick fix should be configuring with ./configure CFLAGS="-g -O2 -Wno-stringop-overflow". I will see if I there's a way fix the underlying problem, but will probably take a while, because of summer holidays.

Thanks a lot! Have a great summer.

Hi, I got the same error as WenfeiXiao. When do you think you can solve the problem? It seems it is an actual error both for "make" and "make install" commands. Looking forward to fixing it.

Have a great summer holiday. :) 😊

I fixed the code on the line mentioned in the printout. My compiler doesn't throw this warning, so it could still be problem elsewhere. Can you see if the latest version of code works for you @WenfeiXiao ?
