Hi Marcus, In the past we've seen some core dumps from FFTW. I don't recall exactly what the conditions were, but it seemed to depend on the compiler version. You might want to try building FFTW from source using the ./configure --enable-single --enable-shared options. Your problem may have something to do with --enable-sse and/or changes in compilers, etc. Eric _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
