[OpenBTS] WARNING -- UNDERRUN in TRX->USRP interface Segmentation fault


#1

Hi all,
Â
I
installed the OpenBTS and GNURadio (svn trunk). I did the svn update
today. I got a segmentation fault when I ran ./transceiver. I found
others
also met this kind of segmentation fault, but I don’t find any
solutions for it through google. Could anyone please tell me how to
solve this problem?

kernel:2.6.25.9
I ran the ./transceiver and got the following:
