It's a pretty ambiguous error. This particular app has about 525 blocks. I'm guessing it's exceeding the total limit for stack space in a process. First check what $ ulimit -a shows. Then try setting -s to something smaller, say 4096, $ ulimit -s 4094 then try running usrp_flex_band.py again. > I've read that similar > errors occur when the target application is compiled without > pthreads, but that's definitely not the case (in fact, the makefile > appears to include the -pthreads option twice).

It looks like somebody tried to install boost into the system path, but didn't use the --layout=system option. If this sounds like something you may have done (perhaps by forgetting to specify the --prefix option to boost when building it the first time), rm /usr/local/libboot*-gcc42-mt*.so* > in order to get it to compile without errors, even though I provided > --with-boost=/opt/boost_1_36_0/ to the configure script (I believe > the compile failed somewhere in gruel).
