sdrtrunk with Windows/aarch64 support

[DSheirer]

I added experimental support to sdrtrunk for windows arm64 but I don't have a way to test it. Feel free to add it to your list of compatible SDR software. If you're able to test it and find any issues, please let me know.

Release: https://github.com/DSheirer/sdrtrunk/releases/tag/v0.6.1-beta-3

Hello @DSheirer!

First off, thanks for working on this! More Windows ARM64 programs are sorely needed for SDRs. Unfortunately, at this time, the SDRTrunk beta listed does not work. It is missing libusb4java:

Once this is fixed I can continue evaluation. Thanks again!

[DSheirer]

Thanks for testing!

I ran into the same issue with OSX on aarch64 and it required someone with access to that OS to compile the native libraries. Is that something that you could do?

Instructions for how to complete it are located here: http://usb4java.org/nativelibs.html (Unsupported Platforms section).

If not, I'll temporarily disable sdtrunk support until we can find someone that can compile the usb4java native library.

[JVital2013]

Yeah, I think I can do that. I'll let you know once I take a look!

Hi @DSheirer,

I just opened two issues on your GitHub.

• Add libusb DLLs to allow loading Windows ARM64 version DSheirer/sdrtrunk#2081 contains the necessary jar to fix the issue I mentioned, so you can work it into your build process. Just dropping it into the lib folder of the current beta works for me. Let me know if you need anything else on this end!
• There's also a minor issue where it attempts to load the SDRPlay library from the wrong location. The issue for that is here: Incorrect SDRPlay Library path on Windows for ARM64 DSheirer/sdrtrunk#2082

Thanks again for your work on this platform!

sdrtrunk updated with libusb native library support for windows aarch64 from this issue: DSheirer/sdrtrunk#2081

Thanks @DSheirer! Unfortunately, the latest nightly is not working at all, while the last beta did work when I slipped in the libusb4java I built and libusb-1.0.dll manually. Here's the new error (looks like it's not finding libusb):

Let me know if I need to statically link libusb to libusb4java. It didn't by default, but I suppose it could be coaxed

[DSheirer]

Is libusb.dll installed in the /windows/system32/ directory on your machine?

[JVital2013]

Looks like that's not the issue anyway, but - libusb-1.0.dll should never be in the Windows folder, despite what I've seen some old programs do (grumble grumble...) The only thing there is WinUSB, configured by Zadig (or manually on Arm64).

For the real problem: they failed to mention this in their build instructions, but https://github.com/usb4java/libusb4java/blob/master/dists/win32/build.bat clearly builds libusb4java statically linked to libusb, which I did not do. I built it dynamically. I've verified this by running dumpbin on the official build, which I should have done before.

I'll re-build libusb4java statically linked to libusb so we don't have this problem. Sorry about that!

[DSheirer]

No worries! Thanks again for doing this! I have limited/no experience on the non-Java languages and would be quite lost trying to figure that out.

[JVital2013]

I'm happy to help! Let's try this again:

• Fix libusb4java on Windows ARM64 DSheirer/sdrtrunk#2084

[JVital2013]

Works great - thanks for the support! I've added SDR Trunk to the site.

[DSheirer]

Great news! Thanks for all your help!
