undefined reference to `_Jv_FindSymbolInExecutable(char const*)'

 hello

 i'm trying to build a gcc-crosscompiler for a mpc823 with java support.
after some little hacks in the configure file of libffi and libjava, i was
able to compile gcc-3.0.1.
i used the following command to configure:

p2:~gcc-build #
../gcc-3.0.1/configure --host=i586-pc-linux --target=powerpc-linux --prefix=
/opt/cross --with-gnu-as --with-gnu-ld --with-cpu=860 --nfp --enable-languag
es=c,java,c++ --enable-threads=posix --disable-multilib

now, after make install, i tried to compile a helloworld program, but it
fails with the following error:

p2:~#gcj --main=helloworld helloworld.java
/opt/cross/lib/gcc-lib/powerpc-linux/3.0.1/../../../../powerpc-linux/lib/lib
gcj.so: undefined reference to `_Jv_FindSymbolInExecutable(char const*)'
/opt/cross/lib/gcc-lib/powerpc-linux/3.0.1/../../../../powerpc-linux/lib/lib
gcjgc.so: undefined reference to `dlopen'
collect2: ld returned 1 exit status

any idea?

thanks for helping
