When you build a program or execute a shell command, the messages are often outputted to both standard output and standard error. If you want to send all ‘printf’ to a log file, use the following command:
make > make.log 2>&1
“2>&1” is the part that redirects standard error to standard out, allowing you to capture all messages.

Also we can use : make 2>& | tee make.log
This will make sure you see the output both on terminal as well as on the File. Most of the times you need not look into the file to check if its successfully compiled.
Thanks for the tip. That’s even better.
