I was using msys2 earlier with gcc 6.4.0 and was working for my project. I upgraded the toolchain and gcc to 9.1.0. Now I am getting this error:
small part of code:
memset(payload, 0, 8192); sprintf(payload, "GET %s%s HTTP/1.1\r\n", dynamic_fota_url, new_firmware_version); sprintf(payload, "%sHost: %s\r\n", payload, dynamic_hostname); sprintf(payload, "%sPort: 443\r\n", payload); sprintf(payload, "%sAccept: */*\r\n\r\n", payload);and error message is:-
