Warning during compiling

GNU Radio
1

Hi Gnuradio List,
I’m compiling GNU Radio on Ubuntu 6.06. I receive this warning:

…/…/…/…/gnuradio-core/src/lib/io/gr_udp_sink.cc: In member function
‘bool gr_udp_sink::open()’:
…/…/…/…/gnuradio-core/src/lib/io/gr_udp_sink.cc:88: warning: NULL
used in arithmetic
…/…/…/…/gnuradio-core/src/lib/io/gr_udp_source.cc: In member
function ‘virtual int gr_udp_source::work(int,
gr_vector_const_void_star&, gr_vector_void_star&)’:
…/…/…/…/gnuradio-core/src/lib/io/gr_udp_source.cc:139: warning:
comparison between signed and unsigned integer expressions

It’s seems to be a no critical error, but I report it the same.

Regards,

Davide A.

This warning did in fact indicate an error. I’ve fixed it.

Thanks, this also indicates a bug.
