gnuradio-3.3.0 Build Error on Ub…

Today, I use another computer to compile gnuradio-3.3.0 and findthe error. >_<!

When I run "make", itruns for a while and then exits with the following error(s):

I have never met this error before and I do some research on google finding the solution. it should change some codes. Next is the diff:
