Arch Linux User Repository

This package hasn't been updated for ages and fails to build anyway. I created a new, current, binary version at https://aur.archlinux.org/packages/swt-bin, which seems to work fine for me.

I had the same issue as last time with the latest version (4.25-1). I have java-11-temurin installed, which includes the missing jni.h file and also fulfills the necessary jdk11-openjdk dependency; however, the PKGBUILD sets the JAVA_HOME to /usr/lib/jvm/java-11-openjdk regardless of whether the openjdk version is installed or not. I could build the package by changing the path to /usr/lib/jvm/java-11-temurin.

It would be great if you could consider cases like this for building the package, @carsme. In the meantime, I'll leave this comment with the workaround for me or anyone else to find the next time I stumble with the same problem.

Does not build:
Caught an exception while logging the end of the build. Exception was:

-> Fehler beim Erstellen: swt

@cknoblauch I cannot reproduce your issue. Installing works fine in the standard Arch Linux Docker image..

jni.h should be included in jdk11-openjdk:

$ pacman -Ql jdk11-openjdk  | grep jni
jdk11-openjdk /usr/lib/jvm/java-11-openjdk/include/jni.h

Can you provide the exact changes to the PKGBUILD that fixed your issue?

Just in case anyone else runs into the same problem: I had both java-11-openjdk and java-11-temurin installed. openjdk is a dependency of this package, and does not include either libawt.so or the jni.h header, at least in my installation.

After manually changing the java-11-openjdk dependency and library path to temurin in the PKGBUILD, the package built correctly. You might consider switching the dependency in the package, @carsme.

I cannot build the latest version (4.23-1). This is the output I get:

Disowned the package. Turns out I don't need it anymore.

Nothing I can do about this, I think.

Edit: Maybe report upstream?
