sdr++ build for Odroid N2+ running Ubuntu 22.04 - Success

[nigelg730]

Just to report the source code 22 Nov 2022 builds and installs cleanly supporting SDRPlay hardware with no errors for an Odroid N2+ running Ubuntu 22.04. Odroid N2+ is a single board computer (4Gb RAM) running a quad core ARM RISC CPU.

It can be done using the published script for the Raspberry Pi build but it will want libvolk2 not the older libvolk1 for the deps.

Be patient make takes 30 minutes.

However tried with source code from master source as of 18 March 2023 and cmake ended with an error, as it failed to find the package containing libzstd which was installed on the Odroid.

Hop this helps anybody who wants sdr++ on a single board computer with a bit more performance than a Raspberry Pi. The onboard audio on an N2+ is very good quality with 192kbps sampling available.

It wasn't installed properly otherwise pkgconfig would find it.
Probably installed the non-dev version

Yes that was it. VMT. Synaptic Package Manager confirmed state of play.

Ubuntu 22.04 standard build for Odroid N2(+) had not included libzstd-dev package, but it did have libzstd1
Standard Ubuntu (amd64 for me) has the libzstd-dev package already installed along with libzstd1 and libzstd1:i386.
So if I understand it right the 22 Nov 2022 source did not need libzstd-dev since it build 'out of the box' but the master source as of 18 March 2023 does need package libzstd-dev.

Next move: I will install libzstd-dev package and try an Odroid N2+ Ubuntu 22.04 build on the master source.

Thanks to Alexandre, and all who contribute, for a wonderful application, most impressed by the lack of bloat.

Nigel, I have an Odroid N2+ doing nothing, so seeing your post makes me wonder if I can use it for 24/7 NOAA reception.
Have you tried predict and wxtoimg alongside sdr++ on your Odroid?
If I know it can work, I'll have a go as I'm not doing so well on Mint on other hardware.

Hi Bob. No direct experience of NOAA decode on Odroid or predict or wxtoimg . I have always found Ubuntu to be very very well supported on the N2(+) and I run version 22.04. In terms of max load that the N2(+) can take I did discover that running a websdr under Firefox and then wstjx that real time decode of the more complex processor intensive data streams like wspr was not possible. It could not complete the wspr decode before the next major frame started. Both Firefox picking up a websdr and wstjx decoding wspr were big loads. But sdr++ should be much lighter than Firefox. I have used fldigi and that runs just fine on Odroid and is avaliable as a package.

Using Ubuntu as your OS should give maximum opportunity for a working result especially as it uses the native GPU well with an excellent driver.

Thanks Nigel, once I get my present project running, I'll have a play and see how I get on with the N2+ as it's a nice sbc just gathering dust.
