Hi,
I was trying to use rx_voice and tx_voice examples, but I found following errors on different Fedora PCs.
I have one computer (Pentium 4 Xeon 3.40GHz processor speed) with Kernel 2.6.11-1.1369_FC4smp, and another computer (Centrino Core Duo T2300
1.66GHz processor speed) with Kernel 2.6.18-1.2200.fc5smp.
When I run rx_voice.py I recieve following errors: a) on FC4 : Segmentation Fault b) on FC5 : terminate called after throwing an instance of 'std::runtime_error'
what(): msg length is not a multiple of d_itemsize Aborted
Then, I tried installing fftw from source code with following options: 1) ./configure --enable-sse --enable-single --enable-shared
2) ./configure --enable-single --enable-shared 3) ./configure --disable-sse --enable-single --enable-shared
but there was no improvement in the program, though all the make check worked perfect. Although GNU Radio works pretty well with the current setup, but I am not able to understand the WHY behind this problem.
Between the time, I am also not able to listen anything on receiver side. I am using RFX2400 boards with following commands:
