Hey folks,

I am running a Ubuntu 24.04.1 on my Turing RK1 SoC. The build process aborts with failed Java2Swift execution.

I retried the build on a Raspberry Pi 5 having Ubuntu 24.04.1 LTS installed, got the very same result.

I installed debug symbols for libc to see where the tool crashed,

An quick update. After repo update I started a new build by issuing make javakit-run. It crashed again but with a different log. See below,

I went over to another build target, jextract-run. Build yielded error complaining about missing compiler flag -abi-comments-in-module-interface:

➜  swift-java git:(main) ✗ make jextract-run

make: *** [Makefile:121: generate-JExtract-interface-files] Error 1

Is there a specific Swift version that builds above target?

[ktoso]

The jextract question is separate from the runtime crash, I answered it here: #81

[DougGregor]

I fixed the crash on Linux as part of #105

I retried the build with make javakit-run but now I get complaints about redefinition of module 'JavaRuntime'. I used the latest toolchain.
Here's an excerpt from the build log
