[Discuss-gnuradio] Python3 or still Python 2.7?

[Chesir, Aaron M.]

Will GNUradio migrate to Python3.X, or will it remain with Python 2.7?

The reason I ask is that (for reasons that unclear), there are syntax 
differences between the two, and Python 3 is *not* backward compatible for some 
of them.

Subject: [EXT] [Discuss-gnuradio] Windows Installers v1.6 for v3.7.13.5 
published

All,

Updated windows installers that include 3.7.13.5 have now been published.

They can be found as always at http://www.gcndevelopment.com/gnuradio.

Key windows specific fixes in the installers include:
1- Windows Audio Sink now doesn't distort for certain audio streams
2- ZeroMQ is working again
3- GR_PREFIX is now defined in the run_gr.bat so that sys-wide configuration 
files will be used correctly.

Numerous dependencies have been updated:
GNURadio -> 3.7.13.5
Qt > 5.12.3
numpy -> 1.64.4
libxml2 -> 2.9.9
libpng -> 1.6.37
UHD -> 3.14.1*
zmq -> 4.3.1
libusb -> 1.0.22
openssl -> 1.0.1r
qwt6 -> 6.1.4
log4cpp -> 1.1.3
pycairo -> 1.17.1
sip -> 4.18

* RC1... a new version will be pushed if RC1 requires changes prior to formal 
release

While no new OOT modules have been added, here's the list of what is included:

gr-acars2
gr-adsb
gr-ais
gr-air-modes
gr-ax25
gr-burst (incl. bitarray)
gr-cdma
gr-display (incl. matplotlib)
gr-eventstream
gr-fosphor
gr-gsm
gr-inspector (incl. tensorflow)
gr-iqbal
gr-lte
gr-mapper
gr-nacl
gr-osmosdr
gr-paint (incl. PIL)
gr-radar
gr-rds
gqrx

and driver support for: UHD / RTL2382 / HackRF / BladeRF / AirSpy / Funcube 
Dongle

Known Issues:

-     (new) Windows Audio Source only supports single channel input.
Use portaudio for stereo source use cases.
-     gr-air-modes gui does not work, but the command line interface will
-     Switching between debug and release versions will cause
intermittent heap corruption issues.  Re-run application.
-     TCP Sink/Server are deprecated and do not function in the
windows version, use zeromq blocks
-     File Sink/Server blocks do not function in the windows version.
-     gr-newmod still does not work without a great deal of workarounds
-     agc3 block will run, but will respond more slowly than on
linux... still under investigation.

A complete stack of symbols is available for the release and debug builds, to 
allow tracing all the way down to python itself.

For those intrepid enough to want to build all of this yourself, the scripts 
are now compatible with building 3.8 or 3.7 by changing the version in 
ConfigInfo.psd1 to 3.8.0, then it should build the correct dependencies to 
support it.  Drivers are built but OOT blocks are not yet built for 3.8.  While 
most of the work in this release was to enable a functioning build for 3.8, I 
am not planning to release an installer for 3.8 at this point, but email me if 
you have a need for a pre-alpha build.

When a 3.8 build is released, they will be installable simultaneously without 
issue.

And finally, to make things a bit easier for the intrepid, I have published an 
AWS AMI image set to a validated build configuration to make it a bit easier 
for others to run the build scripts.  Details on the github site:

Cheers,

Geof
