Hi Sreeraj,
Ok, thanks, trying that – it tells me no apparently and is offering to upgrade a heap of stuff – including some stuff I only just installed a couple of hours ago (!) – and I also – to fill you in – removed my gnuradio installation and re-did by installing gnuradio-companion package – which has helped a bit (some errors I had before at the initial installation didn’t re-occur as you might imagine).
It wants to upgrade stuff including : boost, various libraries including libvolk and python stuff including python-lxml… I can go ahead and let it do this?
Thanks
Jacqueline

Hi Jacqueline,
I tested your files (if_else_mod.py and mod_org.py) on Archlinux with gnuradio versions 3.7.10.1-3 and 3.7.10.1-1, but couldn't reproduce the error. Can you make sure that all your libs are up to date by running "pacman -Syu".

Hi Martin,
Sorry, I did forget to put all that in, still learning including how to use a list for help.
Right - I have it on a VM running Archlinux (4.8.13-1 - I only started a week ago) and I used pacman to install the package gnuradio 3.7.10.1-3.
At that point after installing the gnuradio package I had to go and fetch extra packages (gtk2, gtk3, python-lxml and python2-cheetah) to make the grc work. I am not sure if maybe I should have explicitly installed gnuradio-companion? But once I'd installed the extra packages it worked fine - until I started the python programming part.
Thanks,
Jacqueline
