Add sample of shared library

Open jperedadnr opened this issue 3 years ago • 3 comments

After https://github.com/gluonhq/substrate/issues/1157, provide a sample that creates a shared library.

Hi @jperedadnr is there any sample now or any guide to follow? Or would you mind providing some pointers to create shared lib for both Android and iOS?

EDIT: Just found the HelloSharedLib sample - thanks a lot!

Quick questions:

  1. Is the isolate-based approach the main way to instantiate a shared lib component?

  2. Within that Graal isolate shared lib code, can multiple additional threads be created? For example, we need to run Akka, which will need like 4 threads to schedule actors within the lib instance.

HI @jperedadnr. I fetched your sample code. And I built shared lib for iOS Simulator. i tried run my code on simulator on m1 laptop(Arm/Silicone) And faced with few errors: First case: build shared lib for simulator. Get dylib from folder x86_64-ios and faced with error: "Ignoring file /Users//projects/TestGraalvm/TestGraalvm/HelloSharedLib.dylib, building for iOS Simulator-arm64 but attempting to link with file built for iOS Simulator-x86_64" It is expected for me. Second case: build shared lib for iOS(arm arch). Arch looks the same with real devices. But faced with another error: "building for iOS Simulator, but linking in dylib built for iOS, file '/Users//projects/TestGraalvm/TestGraalvm/HelloSharedLib.dylib' for architecture arm64"

Could you help me with correct building shared lib for simulator on M1 MacBook?

@jperedadnr I tried the HelloSharedLib sample on Windows 10 and Ubuntu 20.04 (WSL2), but I can't get it to create a shared library.

It "succeeds", but there is no compilation or output binaries. It works when I use GraalVM's plugin, but that fails when I use JavaFX:
