In http://gnuradio.org/trac/changeset/11583 there are some files that
use printf. With gcc-4.4 (on Fedora 11) these fail to compile unless you
add #include .
Before I look at fixing this by adding the include, is it “better” to
fix by using iostream classes to replace the printf’s? Do the gnuradio
radio developers prefer one over the other?
