[kaffe] Question about porting kaffe to PXA255

[¼ª¹âƬÓð5000]

Hello,
  I wanted to port kaffe to the Sitsang PXA255(Xscale),i had meeted too many  errors when building the cross-compiling kaffe,and now i was luck,It came through finally!I was not familier with cross-compiling,It's my first time to do it.When i burned kaffe to the board,it error again!
i think though it passed in the making,may be there're still some errors in my settings.

the environment variables as follows:

export PATH=/opt/qt-2.3.2-new/bin:/usr/local/arm-linux/bin:$PATH
export QTDIR=/opt/qt-2.3.2-new/
export JAVAC=/usr/java/j2sdk1.4.2_05/bin/javac

the compiling parameters as follows:

CFLAGS="-D__XSCALE__" NM=arm-linux-nm AR=arm-linux-ar CC=arm-linux-gcc ./configure   --with-awt=qt   --disable-debug   --enable-xscale   --host=arm-linux   --build=i686-linux   --enable-pure-java-math KAFFEH=/usr/local/kaffe/bin/kaffeh   --with-rt-jar=/usr/local/kaffe/jre/lib/rt.jar   --with-threads=unix-jthreads   --prefix=/cvs/xscale  --enable-static=yes --without-esd  --with-qtdir=$QTDIR
--with-jikes=$JAVAC

then make,make install

After building,i port the whole directory of /cvs/xscale to SITSANG,the absolute path of kaffe was the same in both host and Sitsang.
(My Sitsang Board was installed linux-2.4.19,qt-embedded-2.3.2,qtopia-1.5;)

then i tryed this:
export PATH=/cvs/xscale/bin:$PATH
kaffa

end of return:****************************************

I was really confused,What was the problem?I have tryed setting CLASSPATH=KAFFE/lib
,kaffe/jre/lib,but it still can't work,I also tryed javac -classpath.
Is this really the error of CLASSPATH?
Did i must do some more settings on the board?

Does someone meet the same thing to me?Can anybody help me
Any sugestion is appreciate!Thx Reading.
