Hello Ryan
I want to take this opportunity to thank you, Ryan, for supplying (after "years" of trying) a do-able method
for installing a windows 10 version of gnuradio through conda. Truly a find in my emails of this year.
I point out , only a small matter that I was able to overcome. Windows 10 thinks that its main purpose
in life is to prevent me from downloading an "unsigned" (certificate) and puts considerable obstacles
in place which to overcome one must keep hitting "more information", "keep", "run anyways".
Finally one must know to click the start icon->GNU->GNU RADIO COMPANION or equivalent
activate it from a conda start window (which I have not yet tried (with gnuradio-companion).
I have had, and am grateful to you, my first success at activating gnuradio companion on windows (10) ( I
used the start icon->gnu radio->gnu radio companion approach). I use
an Ubuntu 20.04 with gnuradio for my approach to learning gnuradio methodology.
In any event, I thank you.
regards
Jerry, VE3OBX

Hi Brendan,
I can't comment on the particular errors you're seeing with GR 3.9, but I can offer an alternative to building from source. I maintain a collection of packages for conda-forge that use the conda package manager, including UHD and GNU Radio. Because of the way conda works, these are installable on practically any Linux base OS (or macOS, or Windows) and the installation is contained to a single directory. So if you want to try it but it doesn't work out, you won't be causing a new mess that you have to clean up.
Here are the links to an all-in-one installer:
https://github.com/ryanvolz/radioconda
and instructions for the à la carte approach:
https://wiki.gnuradio.org/index.php/CondaInstall
Either way, you have the option of either:
GR 3.9.1 + UHD 4.0.0 (with Python bindings)
or
GR 3.8.3 + UHD 3.15 (with Python bindings)
I hope that's useful!
Cheers,
Ryan

However, in this case I don't have much choice, as the Ettus USRP driver I am using (UHD v4.0) is not supported by the standard GNU Radio binaries. If you know of a way to install a GNU Radio binary that will let me use a USRP driver of my choosing, please let me know.

However, regardless of which driver version I use, it will have to be built from source with the -DENABLE_PYTHON_API compiler flag set to ON (the default is OFF), as I require this API for my project. (The obvious alternative would be to import the GNU Radio library into my Python project, rather than the Ettus API. I don't have any experience with this, but I would be willing to give it a try.)
