[gentoo-embedded] jamvm

Hi,

Has anybody managed to install jamvm and classpath with hardened/uclibc?

gnu-classpath fails to emerge because there is no java vm - and the
javavm is supposed to be jamvm.

Any hints?

According to the ebuild gnu-classpath requires jikes to compile due to
other compilers requiring a particular jvm or incorrect compilation of
the app.  With this is mind is that the error you are receiving?

Yes. jikes can't find the java vm, which is what im trying to install. I
need to bootstrap java somehow.

I tried to run "emerge --nodeps jamvm" and it complains about not
finding classpath. However, if I run ./configure without the 
--with-classpath-install-dir=/usr then it compiles just fine.

I managed to compile jamvm-1.4.4-r1 with --nodeps and this patch:

gnu-classpath failed on configure due to missing gconf though.
