Hello everyone,
First of all I apologize for this direct message. I went through the
website https://savannah.gnu.org/ and only found this address where I can
post my query. I am sorru if I posted at the wrong place. Below is the
description of the problem we are facing.
You have reached the mailing list for people who hack on Savannah.
Savannah is the software forge for people committed to free software.
The web site, the version control hosting, that type of thing.
But you are asking about GNU Classpath. We don't know too much
about specific projects here. It would be better to look at the
project and see what it says about where to get help.
Looking at the Savannah web page here I see this list of mailing lists
for the Classpath project.
https://savannah.gnu.org/mail/?group=classpath
I suggest starting off by sending your request to the
classp...@gnu.org mailing list as a general good place to start asking
questions about your problem.
Good luck!
Bob
We have cross-compiled the gnu classpath 0.98 and jamvm 1.5_4 for our arm
xscale device. When we run helloworld program, it works perfectly fine. But
when we run gui applications, there is no response. Below are our commands
which we gave for cross-compiling:
GNU CLASSPATH:
./configure --host=arm-xscale-linux-gnueabi --prefix=/usr/local
--disable-examples --with-x --disable-qt-peer --disable-gtk-peer
--disable-gconf-peer --disable-plugin --enable-alsa --disable-dssi
--with-escher=/home/warrior/java-project/escher-0.3/src
--enable-local-sockets --enable-collections --enable-xmlj --disable-Werror
--enable-tools --enable-default-toolkit=gnu.java.awt.peer.x.XToolkit
make
make install
JAMVM:
./configure --host arm-xscale-linux-gnueabi --prefix=/usr/local
--with-classpath-install-dir=/usr/local –enable-ffi
make
make install
We then transfer the required files to our device.
we run our programs as
jamvm helloworld
jamvm -verbose Button
helloworld runs perfectly fine and gives the desired output in proper time.
But when we run any gui sample we receive following error:
Exception in thread main java.lang.ExceptionInInitializerError
at gnu.java.awt.peer.x.XToolkit.getClasspathFontPeer(XToolkit.java:208)
at java.awt.Font.getPeerFromToolkit(Font.java:329)
...
Caused by: java.lang.NullPointerException
at java.io.InputStreamReader.init(InputStreamReader.java:208)

at gnu.java.awt.font.OpenTypeFontPeer.clinit(OpenTypeFontPeer.java:93)
at gnu.java.awt.peer.x.XToolkit.getClasspathFontPeer(XToolkit.java:208)
Can someone please guide us on this. This is becoming very critical.
Earlier we thought this to be jamvm issue, but on jamvm forums , it can out
that we are missing something while cross-compiling gnu classpath.
It will be a great help if someone can direct us towards fixing this to see
what we are missing to get the gui applications running with jamvm. We have
made a small sample using java swing which creates a frame and 2 buttons
over it.
Thanks in advance.
Aditya
