Hi Steve,<br>
<br>
I have been playing around for a while now using a few different ubuntu and debian distributions. So far I've only had success with my 11.04 virtual machines. I took some wireshark captures of some P25 samples running through Bob's flowgraph in both debian wheezy and ubuntu 11.04, the "good" capture (<a href="https://docs.google.com/open?id=0B8J3fNC5VR23akJ1Zl9xNkNHeHM" target="_blank">https://docs.google.com/open?id=0B8J3fNC5VR23akJ1Zl9xNkNHeHM</a>) contains exactly what I would expect with correct NIDs, while the "bad" capture (<a href="https://docs.google.com/open?id=0B8J3fNC5VR23NlA2aGdWVDlHYUE" target="_blank">https://docs.google.com/open?id=0B8J3fNC5VR23NlA2aGdWVDlHYUE</a>) has packets with NIDs that are all zero with the occasional 1 in the LSB. From the packets I glanced at, the data after the NID is the same in each capture. <br>
<br>
I have no idea what the differences are in the dependencies between my debian setup and ubuntu vm, but I have tried building in debian with gcc-4.5 and boost 1.46 (instead of gcc-4.6 and boost 1.49) and have not had any luck. I have also tried a few versions of gnuradio (3.4.2, 3.5.3 and 3.6.1) without any luck. Any other ideas to help get it working or figure out the cause of the problem would be welcome.<br>
<br>
Thanks,<br>
Mark</p><div><br>
