[Jamvm-general] Unable to run GUI application using cross-compiled jamvm for arm

[Adityadham <adi...@gm...>]

Hello everyone,

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
--enable-local-sockets --enable-collections --enable-xmlj
--enable-default-toolkit=gnu.java.awt.peer.gtk.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 and give verbose option it shows that it is
loading and linking a lot of classes which are all present and finally it
stops after displaying the following statements: 
[Loaded gnu/java/awt/BitMaskExtent from
/usr/local/share/classpath/glibj.zip] 
[Linking class gnu/java/awt/BitMaskExtent]

Can someone please guide us on this. This is becoming very critical.


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.
