In the file to which you redirected the standard output and error of the make command - or the file created by tee, if 
piped the standard output and error of the make command to "tee errs" so that the errors are printed *and* get written 
to the file "errs".

If you *haven't* redirected the output, it's in your terminal window, so you might be able to scroll back to find the 
error.  (I presume nobody uses *real* terminals these days. :-))

No, there shouldn't be.

There might be an error further back.  That's why sending the build output to a file is useful - you can then, for 
example, open the file in a text editor and look for the word "error" (note that some source files may have "error" in 
their names, so skip them).
