OpenJDK on ARM

Today I pulled myself together and tried to build IcedTea for ARM again. I had two options: to build it natively on an ARM board or try to cross-compile it. I decided to try the cross-compile approach.

The build did not fully finish, because I don't have ALSA libraries in my cross-build enviroment, so I just took an j2re-image from an x86_64 build and replaced

bin/java

with the cross-compiled one and copied

openjdk/control/build/linux-arm/lib/arm/

into the x86_64 j2re-image.

And it works!!!

$ uname -m
armv5tejl
$ java -version
java version "1.6.0"
IcedTea Runtime Environment (build 1.6.0-b06)
CACAO (build 0.98+svn, JIT mode)

(btw. this output calls 10273 Java methods)

Now I'm testing applications like DaCapo and most benchmarks of DaCapo already pass in small size.
