DRLVM bootclasspath
As a PhD student looking for open-source infrastructure, it's
exciting to see how much progress is being made in the Harmony project!
That said, I've run into some strange behavior trying to run the
DRLVM on my machine (x86 running Fedora Core 1). The VM itself seems
to build fine, but I get the following error when I try to run it
(from <exctract_dir>/build/lnx_ia32_gcc_release/deploy/jre/bin)
> ./ij.sh Hello
java/lang/NoClassDefFoundError : java/lang/VMClassRegistry
After tinkering around a bit, I have managed to run Hello.class by
explicitly setting the bootclasspath:
> ./ij.sh -Xbootclasspath:<extract_dir>/build/lnx_ia32_gcc_release/
deploy/jre/lib/boot/kernel.jar:<extract_dir>/build/
lnx_ia32_gcc_release/deploy/jre/lib/boot/luni.jar:<extract_dir>/build/
lnx_ia32_gcc_release/deploy/jre/lib/boot/luni-kernel-
stubs.jar:<extract_dir>/build/lnx_ia32_gcc_release/deploy/jre/lib/
boot/nio.jar:<extract_dir>/build/lnx_ia32_gcc_release/deploy/jre/lib/
boot/security.jar:<extract_dir>/build/lnx_ia32_gcc_release/deploy/jre/
lib/boot/nio_char.jar:<extract_dir>/build/lnx_ia32_gcc_release/deploy/
jre/lib/boot/icu4jni-3.4.jar Hello
Any ideas what is wrong?
FYI, I am using the latest (as of yesterday) prebuilt Harmony class
libraries.
Thanks,
Naveen

Yes, provided you run the debug build (built with BUILD_CFG=debug):
Just run it with the flag
-Xtrace:init.properties
To make this possible on the release build, you'd need to apply the following patch
and to use different command-line argument:
-verbose:init.properties
--- a/vm/vmcore/src/init/properties.cpp
+++ b/vm/vmcore/src/init/properties.cpp

Whether does it mean your issue exists yet? Just FYI I have no problem for
Fedora 5.
All works fine.
Is there a way to check what the current setting for the
> bootclasspath is?
Yep. Look at the
build/lnx_ia32_gcc_release/deploy/jre/lib/boot/bootclasspath.properties
file.
Thanks,
Vladimir.

It is unset.
Is there a way to check what the current setting for the
bootclasspath is?

I'm not sure but could you please unset the CLASSPATH env variable and try
again?

I believe there are no needs to make this.
