Re: [Discuss-gnuradio] Gnuradio 3.7.2 Windows?

[Mike Willis]

Thanks Andrew – I had goggled it and not found anything helpful. I am not sure an earlier version of pyopengl would work but I suppose it is worth a try.

 

I don’t want an SDR like HDSDR, I want to use Gnuradio to do things most SDRs can not do – 3.6.5 worked but everyone has now moved on to 3.7 and I was hoping, perhaps naively, that it would be sensible to try to install it under windows.

The problem with Gnuradio isn’t so much understanding the DSP side – it’s installing and getting the system to work and keeping it working. The main problem I find is the continuous changing of the basic framework often breaks many things in the process in a way that only an experienced python programmer can fathom how to fix. Even the supplied examples don’t work because the modules have been shuffled around, renamed etc. Instructions rapidly become outdated and the new user then has no clue why the advice they find on the Gnuradio site doesn’t work. Backwards compatibility isn’t a priority when developing a new framework, but Gnuradio in its present form has been around for 10 years so it should really have settled down and there shouldn’t be these big break everything changes with each new minor release.  If it were truly stable I think it would be much more successful by now.

Hello,

 

>Has anyone actually managed to successfully install and run the latest gnuradio in Windows 7

 

Yes, but not using those instruction, building from source is much more fun :), but they look like they worked for you outside of that error.

 

Also If you Google your error other people are having that problem as well, so it's not Gnuradio related but something with pyopengl on certain windows systems. I'd say try installing an older version of pyopengl.

While I agree it's not quite user friendly it is a software defined radio API and development system, so it's not gonna be like going to be like installing a program and listening to the radio, you will need some software savvyness to build a SDR. If you just want to use a SDR there are many already made programs for individual tasks.

I don’t believe this page is up to date as I just cannot get it to work. It was OK if something of a struggle with 3.6.

 

Although it nearly works, the gui modules do not work at all but produce a rather unhelpful error message. E.g. this is with a wxgui fft sink added to the dialtone example. The tone works fine but not with any gui.

 

“TypeError: ("No array-type handler for type <class 'ctypes.c_ulong'> (value: c_ulong(0L)) registered", <OpenGL.converters.CallFuncPyConverter object at 0x0482A3D0>)

”

 

How am I supposed to understand this? It looks to me like a problem with pyopengl but that has been installed as indicated in the instructions. Are the instructions wrong? Is this the wrong version? Does it just not work anyway?

 

I must admit to getting extremely frustrated with gnuradio and its lack or usability for those of us who are not professional programmers.
