Question 2.5. What's the difference between |--enable-3dnow| and |--enable-k7|?
|--enable-k7| enables 3DNow! instructions on K7 processors (AMD Athlon and its variants). K7 support is provided by assembly routines generated by a special purpose compiler.
|--enable-3dnow| enables generic 3DNow! support using |gcc| builtin functions. This works on earlier AMD processors, but it is not as fast as our special assembly routines.

Hi, Eric
Toby's suggestion helped me solve the problem. If I
configure "without" the --enable-sse option, then
everything works well. Is --enable-sse option
necessary here?
It's only necessary if you want it to go fast... [For most current uses within GNU Radio it won't matter]
If you're on an Athlon, use --enable-3dnow instead.
Thanks to you guys
