How to build and install 52-sdrplay-support #1328

Closed srs4511351 closed 1 year ago

srs4511351 commented 1 year ago

I have sdrtrunk Version 0.5.0 Beta 5 running on a raspberry Pi 4. The OS is DietPi 64 bit bookworm. openjdk version "11.0.16" 2022-07-19 OpenJDK Runtime Environment (build 11.0.16+8-post-Debian-1) OpenJDK 64-Bit Server VM (build 11.0.16+8-post-Debian-1, mixed mode)

I see that there is a 52-sdrplay-support branch and I would like to try it out with my RSP1A.

The wiki says to download and extract a zip archive, but I cannot find one for the 52-sdrplay-support branch. I downloaded it, but the files needed to run it aren't there. cd ~/ git clone https://github.com/DSheirer/sdrtrunk.git cd sdrtrunk git checkout 52-sdrplay-support

What needs to be done to get it running?

Thanks, Steve

See the developer instructions in the README. It says to build it you have to have at least OpenJDK 17.

I have been trying to get this branch to build but have been unsuccessful and get build errors. I also get build errors with the master and 0.4.0 branch. I have openJDK 19 and the build fails both on ubuntu and arch.

My second attempt was with JRE 17. The errors were different, but it still failed. Please let me know if you get it to work. There is a note somewhere and issues submitted that it only uses SDRplay API 2. API 3.07 has been the standard for over a year now and a newer one is on the way. It is already available for Windows.

@srs4511351 I gave up on sdrtrunk. My use case was to get a P25 SDR decoder working and that was it. I was able to get that working using boatbod's release + an ubuntu 20.04 VM.

It would be very helpful if the maintainer of this project could release a Dockerfile that builds the release artifacts. @DSheirer : the build instructions seem to be missing something. I'm not familiar with gradle all too much but I've tried multiple combinations of JDK≥17 and OS's. What's your build process?

I read that they bumped SDRplay support to the next release. If they would use SoapySDR, it would open up support for a wide range of SDRs. I have sdrtrunk running on my Raspberry Pi, but it is with a RTL-SDR. It's not mine, so I won't always have it. The CPU load is so high that I turn off the spectrum and waterfall display. It seems that Java is very CPU intensive. I also use op25, boatbod build. It doesn't work with GNUradio > 3.8, so they will eventually have to support that. Their CPU load is very low. I have my build procedure online. It shows you how to start from a Raspberry PI OS image and install a wide range of applications and utilities.

Closing this as an issue. Feel free to continue the conversation to Google groups or Discord.

I'm still developing on the #52 branch for the 0.6.0 milestone. I'm trying to get 0.5.0 finished and released so that I can focus on sdrplay support again.
