Has anyone tried to build a Java compiler package for OpenWrt? I am investigating doing this. I see the lang/jamvm JVM, but no compiler akin to devel/gcc or lang/golang. I have packaged a number of things, but I suspect this will be a bit more of a challenge. Hence my question here.
In a related context, I recently wrote: ----- I updated classpath and jamvm over 5 years ago to support a project I am no longer involved with. Upstream jamvm has not changed in almost 6 years, with language support frozen at Java 8. Upstream classpath has not changed in 8 years, with language support frozen at Java 7. (My project was specifically compiled at v1.5). jamvm depends on classpath; if classpath is removed, jamvm should be as well. I am no longer in a position to actively maintain either of these packages. ----- So, Java support in OpenWRT arguably requires starting with the JVM and making sure it supports a modern revision of the language. Then, either updating classpath to a modern version or possibly adopting the classlib from OpenJDK. With this done, you may be able to run Java classes compiled with modern tools; IIRC, support for v1.5 compilation was removed from the JDK several versions ago. [ Also, My application pared-down classpath to just the necessary classes; even if the OpenWRT platform in use has a lot of memory, classloading from flash is _slow_. ] Running JDK (javac) per se on OpenWRT strikes me as not being worth the effort. Just getting the Java run-time environment modernized on OpenWRT is a full-time job :-) Cheers, Dana _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
