Re: {Disarmed} Re: [WVURAIL/gr-radio_astro] Installation difficulty (#20)

Hi Gisle,

I think you’ve revealed the problem that we’ve not “Upgraded” to 3.8.

What build environment are you working in Gnuradio 3.7 or 3.8?

We’ve been making half hearted, repeatedly failed, attempts to get our code

running with 3.8.  There are just too many changes to figure them all out.

The gnuradio dynamic environment is great for code=super=heroes, but I’m afraid I’m stuck.

Sorry,

Glen

PS that’s why I’m recommending just downloading the gnuradio 3.7 with the

whole OS for Raspberry Pi 4.

Here’s the Raspberry PI OS for SDRs. It will run on a Pi 3, but runs
much better on a Pi 4. It is BIG, 2.3 Gigabytes:
https://drive.google.com/file/d/1yjCdpyF_T0Lb4uwVfz-mSzp4DTqDq6Uj/view?usp=sharing

Our goal was to make it easy to get started with home radio astronomy.

The download completely overwrites the previous contends of the SDcard.
You can start with a new blank card (8, 16 or 32 GB).

The OS has absolutely all the code you need to observe, except your
horn, and the SDR.  The code works with AIRSPY full-size (10 MHz), NESDR, 
AIRSPY mini (6 MHz), SDRplay RSP1A dongles.

The OS has Gnuradio 3.7+ installed, with all the WVURAIL code also installed.

You have to login via VNC (Virtual Network Connection) on your PC.
The PI address is 192.168.1.110 for the Raspberry Pi.

PSS, We’d love to have a complete Raspberry PI OS download that included

an operating Gnuradio 3.8, if it included support for AIRSPY, SDRPlay, NESDR

and PlutoSdr.

I gave a live demo of a home radio telescope in operation, detecting the Milky Way.     

The very beginning shows the telescope in operation, and the last 5 minutes

shows the strong Milky Way signal you can see with only a 10inch diameter horn.

My wife, Katherine, assisted by pointing the telescope on and off of the Milky Way.

What exactly was the error message?

detect_impl.cc(121,29): error: use of undeclared identifier 'CLOCK_REALTIME'

      int r = clock_gettime(CLOCK_REALTIME, &ts);

Did the other modules build?

No, the mess the GNU-radio folks created when going from boost::shared_ptr to std::shared_ptr has made it impossible.
