FFTW causes a segfault when built with gcc 3.4.2 under FC3. See: http://lists.gnu.org/archive/html/discuss-gnuradio/2005-10/msg00241.html
Often in the past, this has been confused with a problem with wxPython because everyone notices it in usrp_fft.py. This may or may not be your problem. To be sure run, one of the wxPython demo scripts that came with your wxPython distribution. If that works, rebuild FFTW without the --enable-sse flag. If you don't get a segfault then, consider upgrading to gcc 3.4.4. --enable-sse works with gcc 3.4.4 (see the above link). cheers, - Lee On Wed, 2005-12-14 at 05:31 +0000, kelvin loi wrote: > Hi All! > I managed to solve the problem of "max_stream" by > re-installing everything includes baseline as well.
