I've just installed PothosSDR-2017.06.21-vc14-x64.exe and python-2.7.13.amd64.msi and I have a problem with some of my GRC flow graphs that contain 'WX GUI FFT Sink'. Even with just 'Noise Source' connected to 'WX GUI FFT Sink' I get the following error message:

Executing: C:\Python27\python.exe -u D:\GRC\top_block.py

RuntimeError: The segment is already unlocked.

If I replace 'WX GUI FFT Sink' with 'WX GUI Scope Sink', the flow graph works.

Hi Do you think you could add complete GNU Radio + OsmoSDR into Pothos installer?

I would like to use GNU Radio on windows and its a strugle to build everything from source

Thanks for Anwsering and Best Regards

Right now the only option for Windows users to get SoapySDR libraries (and basic SoapySDRUtil executable) is PothosSDR installer bundle, which is rather large (more than 500MB after installation), contains many applications (e.g. GNU Radio, GQRX, CubicSDR, Pothos GUI, Zadig, etc.) and is only available for 64-bit Windows.

It would be great if you could provide minimal installer containing only SoapySDR, SoapySDR device drivers (all drivers and theirs required libraries are only about 20MB together), Python SoapySDR bindings and SoapySDRUtil executable. And it would be even better if you could also provide installer for 32-bit Windows.

Alternatively SoapySDR Python bindings could be separated and provided on PyPI which is standard for Python packages nowadays (even large bindings like PyQt5 are now available in PyPI).

Copied from original issue: pothosware/SoapySDR#122

We have Python2 and Python3 modules. Find a way to add them to the respective python paths.

From @vsboost on July 14, 2018 6:6

Just wondering why i get these errors continuously, and if there is something i can do to make them stop.

Thanks

Hi do you think you could add gr-rftap to build?

gr-rftap: https://github.com/rftap/gr-rftap

gr-rftap info: https://rftap.github.io/

The snap support branches have been merged, but only into master. We can add prefix setting now, but it wont take effect until another release.

• Reference: gnuradio/volk#100
• gnuradio/gnuradio#1077

Now that volk is a separate project, we can build and use it separately with -DENABLE_INTERNAL_VOLK=OFF passed to GNU Radio. This will make it easier to apply patches to volk like: https://github.com/pothosware/PothosSDR/blob/master/patches/volk_skip_profile_app_vc11.diff

Hi,

I am testing out Pothos GUI 0.5.1 PothosSDR-2017.11.26-vc14-x64 on a computer with a 4K display, and while everything appears to display OK, the page size seems very limited -- I only have enough room to place maybe 6 or so blocks. There seems to be an invisible barrier that prevents me from attempting to drag blocks out of this small area.

I cannot find any settings (documented or otherwise) to enlarge this usable area. Any pointers?

By the way, very nice work on this new GUI! Impressive.

Regards, Devin

In order to allow users to develop qt apps against the environment, we need to investigate the ABI compatibility across Qt versions, select a version of Qt to build against that will be easiest for user's to download and install.

• The dev environment ships qt runtime dlls
• Users must download Qt development package
• Available versions for development packages vs MSVC versions

I built my Windows system with "PothosSDR-2018.04.26-vc14-x64.exe " which installed support for the 0.6 Lib version. How do I update this install to support 0.7?

Thank you,

Jack

http://sourceforge.net/projects/boost/files/boost-binaries/1.60.0/

Should not be needed, we can detect the root relative to the DLL. The env vars tend to stop on other installs of SoapySDR etc

• Possibly blocking dependencies, have to see what Qt has available
  • Find qt5 development installers for MSVC 2017
  • Find boost development installers for MSVC 2017
• Some cmake build strings and that should do it
• Close when installers for this release are available

• https://github.com/myriadrf/LoRa-SDR

Close issue when new binaries are posted

Noticed that Soapy is pretty indiscriminate (under OSX 10.10) and verbose about trying to open anything under {INSTALL_ROOT}/lib:

bladeRF fails to build, saying that it cannot find pthread.h. The file can be found in C:\PothosSDR-dev\PothosSDR\build\Source\Pthreads, but the compiler invocation does not seem to include /I"C:\PothosSDR-dev\PothosSDR\build\Source\Pthreads".

Looking to create 32-bit version of the environment to go along with the current 64-bit environment.

• download various pre-built 32-bit depedencies
• abstract build environment to select 32-bit dlls
• testing, etc...

The build system for this development environment is just a very large batch script that installs dependencies, clone repositories, and configures and builds the software packages. This is great until something crashes a long the way as the script isn't very fault tolerant. What's cool is that CMake has this External Project module that creates build targets for other projects. You can enter git repos and build commands, and dependencies on other projects. In essence, I can make a CMake project to build other CMake projects that handles faults better and can build based on dependency ordering.

Currently the precompiled pthreads pulls in vc10 runtime. And it has a possible MSVC2015 ABI timespec issue: Nuand/bladeRF#447 So we are either going to compile it once for each VC manually, or somehow add it to the build.

Maybe continue to build 3.4 if we work out packaging multiple simultaneous versions:

I installed my LimeSDR PCIe on a new PC and installed the latest build PothosSDR-2018.03.12-vc14-x64.exe . In GQRX I can listen at 40MS/s, but anything higher gives me tons of noise, the spectrum becomes all yellow.

In my own C++ program using SoapySDR, I often have errors while receiving on one channel (readStream returns -1), and when I try to use 2 channels, I get usually 3 warnings Channel alignment failed and then I can't receive anything.

After updating the drivers, BIOS and all, I uninstalled Pothos and installed the previous build PothosSDR-2018.02.05-vc14-x64.exe , like on the previous PC, and everything went back to working normally.

OS version : windows 10

Hi I've installed pothos again and I've set C:\Program Files (x86)\gnuradio\etc\gnuradio\conf.d\gr-audio.conf and changed from auto to portaudio:

[code]

This file contains system wide configuration data for GNU Radio.

You may override any setting on a per-user basis by editing

~/.gnuradio/config.conf

specify which audio module to load, or use "auto" to have the system

select one. Valid choices depend on your OS and which modules

you've installed, but typically include:

auto, alsa, oss, portaudio, jack, osx, windows

[audio]

audio_module = portaudio
[/code]

but it still wan't to use Audio source arch: windows but I know I've setted the right config?

Hi. Windows 10 64 bit trying to install.
Get an error "can not write to file" C:\Program Files\PothosSDR\bin\SoapySDR.dll"

Can ignore, after which more files fail.
Did the same installation as administrator with the same error(s).

Tried to install in different folder, C:\benno\pothossdr but then installation completes but starting the software gives errors about missing files in C:\Program Files\PothosSDR but that is right because that is not where I installed it.

Any help?

Thanks,
Ben

With this now released, add it to the build

LimeSuite requires cypress API and wx (which we currently use for cubic). In addition, it provides a SoapySDR support module, so this must be built after SoapySDR.

Hi Here I am prepairing a wishlist of some project that you could include into GNURadio portion of Pothos SDR:

1. GR-RDS: https://github.com/bastibl/gr-rds
   • The most official and updated one
   • PRIORITY: HIGH
2. GR-DRM: https://github.com/kit-cel/gr-drm
   • most official and updated
   • PRIORITY: LOW
   • PS: I don't know how would you get FAAD2 and FAAC working?? and there are some hier_blocks flowgraphs that you nust open after compiling (linux) so I don't know how would this behave on windows
3. GR-DVBT/S/S2:
   • GR-DVBT: https://github.com/BogdanDIA/gr-dvbt
   • GR-DVBS: https://github.com/drmpeg/gr-dvbs
   • GR-DVBS2: https://github.com/drmpeg/gr-dvbs2
   • to use theese you would also need gr-qam: https://github.com/argilo/gr-qam
   • PRIORITY: VERY LOW

PS: What do theese do?: https://github.com/guruofquality/grextras
PPS: DO you think you could get GNURadio (https://gnuradio.org/redmine/projects/gnuradio/repository/revisions/master/show/gr-zeromq) to work with ZeroMQ: http://zeromq.org/

• Update tutorial screen-shot as well

I got a report that the x86 runtime was needed with the installer. Something was either built wrong, or a prebuilt pulled this in. This doesn’t seem right, so this is an open issue to investigate.

The dot tool is used to render the topology for debug purposes. We should find a way to ship dot.exe and minimal dependencies with it so it can be used w/ the GUI.

When boost and qt development environments are available, provided installers built with msvc 2015. Right now MSVC 2015 is in RC, so it might be some time.

Many Linux and macOS users use baudline for analyzing SDR recordings, however its source re-distribution policy is restrictive. Inspectrum is an alternative and also uses cmake for its build environment. It requires:

• fftw - (already in PothosSDR)
• liquid-dsp (already in PothosSDR)
• qt5 (already in PothosSDR)
• mman-win32

Please consider adding Inspectrum so users can easily view SDR dumps.

Currently, the development environment is just a zip file that must be unpacked in a specific directory (C:/PothosSDR). To move the environment to another location would require setting the environment variables of various software packages so they can locate various plugins and resources. With an installer, the user can select the destination, and all of the environment variables including the PATH can be set automatically. Start menu short cuts as well!

Do this in the same build so we can just repackage the same build into multiple installers

• python modules
• registry edits
• devel files
• runtime library
• soapysdr modules
• various sdr drivers

This should prioritize the DLLs from the installer (need to confirm this) and avoid the need for setting the PATH for start menu items. Command line still needs a proper path set or changing CWD to PothosSDR/bin presumably.

• Closing this when the new installers are up
• Update the docs about setting the path (only for command line)

This is not realy GR whishlist but as you have good linux to windows porting skils I was wondering if you could maybe give this a try
HackTV is a nice Analog TV Transmitter that supports PAL, NTSC, SECAM (in the future) it also has Videocrypt support (have to find a Videocrypt decoder somewhere to test it)
https://github.com/fsphil/hacktv
for now it only supports generating to file or directly to HackRF

I tried to compile this on linux for windows with MinGW: fsphil/hacktv#4 but failed, then tried this again on mysys2 but failed again on the exact same error (not sure why it would compile fine on linux but complain when doing it for windows

You think you could post some script or instructions on how do you add an OOT module to GNuRadio (you could use this one: https://github.com/lscardoso/gr-ntsc-rc as an example) on Windows because it would be great if it would be as easy as running make on linux, I am not sure if PothosSDR even comes with required file to be able to do this? (would love to try this on msys2 if possible)

Modify the registry to include paths for the python2.7 and 3.4 modules. Note, some projects require modifications to prefix for the different python versions.
