tf1 compiling error - Githubissues

Hi, my name is Michele, thanks for your open-source code. I was looking for a solution for a project and the tf1 library seems to be a great one. Unfortunately, I encountered some problems compiling the library:

I had to change std=c++11 to std=c++14 in these two lines in the Makefile:
```
axmult.o: axmult.cc
g++ -std=c++14 $^ -c -o $@
```

axqconv.so: axqconv.cc axmult.cc axmult.h approximate_selector.h g++ -std=c++14 -Wno-ignored-attributes -Wno-deprecated-declarations -shared $(filter-out %.h, $^) -o $@ -fPIC ${TF_CFLAGS} ${TF_LFLAGS} -O2


- I obtained these errors while compiling:

Could you help me? :)
