Arch Linux User Repository

Thanks you, that helped some. I did have those things installed and up to date already already, but even after reinstalling them, /usr/bin/javac was a broken link to /usr/lib/jvm/default/bin/javac. I had to make it link to this instead: /usr/lib/jvm/java-11-openjdk/bin/javac

Now I can get a little farther in the build process for kawa but it can't find libjli.so. I tried putting /usr/lib/jvm/java-11-openjdk/lib/jli/ in my $PATH but that didn't help.

Maybe I haven't configured java right

@after javac is included in the 'java-environment-common' package, which comes as a dep of jdk-openjdk.

I didn't manage to build this, there's some dependency error.

I couldn't find javac in aurman. After googling, I guess I need to install jdk-devel too. I'll let you know if that works.

edit: i couldn't build jdk-devel either, something wrong with the pkgbuild. so i don't know if it would have worked or not.
