Hello Peter,

thanks for reporting the issues.

Do you have FFTW 3 installed? OpenVIP has been written to link
against FFTW 2.x. This can be achieved using -lfftw, while FFTW 3
changed it to -lfftw3. I'll fix the Jamfile to link against FFTW
3, but I have to read FFTW docs first since it is not 100%
backward compatible with FFTW 2.x. Anyway, all FFTW plugins are
optional so you can safely leave them out.

Did you set OPENVIP_HOME as described in the README file?

If you have OPENVIP_HOME set correctly, then I have no idea what
might be wrong. The load_network_from_string Python function is
implemented using the NetworkFormatLoader::LoadFromString C++
function, which can be found in
openvip/src/core/networkloader.cpp. The error means that this
function returned false - could you find out why?
