Trouble building WALA on my Samsung Galaxy Z Fold 5

[juliandolby]

Using Andronix to get a user-mode Linux on my phone, I cloned WALA, but the build failed as shown below. It appears not to understand that the phone is an aarch64 device. There is magic to use the native SWT libs, but the phone seems to confuse it. Does anyone know how it works?

`dolby@localhost:~/WALA$ ./gradlew clean build Calculating task graph as no cached configuration is available for tasks: clean build Type-safe project accessors is an incubating feature.

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.11/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

There is magic to use the native SWT libs, but the phone seems to confuse it. Does anyone know how it works?

We trigger that magic here:

https://github.com/wala/WALA/blob/a44aa599fbe19890c5f657f73b16d730ade8a03c/build-logic/src/main/kotlin/com/ibm/wala/gradle/eclipse-maven-central.gradle.kts#L74

Documentation for useNativesForRunningPlatform can be found here.

If there is some platform-specific JAR containing natives suitable for a Samsung Galaxy Z Fold 5, but we’re just not picking that dependency correctly, then perhaps we need to allow substitution in the style shown here.

If there is no platform-specific JAR containing natives suitable for a Samsung Galaxy Z Fold 5, then either:

• we cannot build WALA on this platform,
• we need to exclude the ide subproject on this platform, or
• we need to extract the ide subproject into its own GitHub project that depends on core WALA as previously considered in #462.

@juliandolby are you able to build just the projects you need? E.g., ./gradlew :core:assemble, or ./gradlew :cast:java:ecj:assemble? I'm assuming you don't need the IDE functionality for this scenario.

Thanks! That worked. And I can even publishToMavenLocal.

BTW, I think I tracked the issue to code in diffplug just reporting unknown for arm64 on Linux, and I opened an issue with them.

Thanks for chasing the problem into diffplug. Can you provide a link to the diffplug issue that you filed? That will help us keep track of the relationship between this initial report and that possible root cause.

Looks like it's https://github.com/diffplug/durian-swt/issues/29
