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

From: Adityadham <adi...@gm...> - 2013-03-22 14:37:49

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.

I believe you have cross-compiled gnu-classpath with an incompatible set of
options.
If you want to use the gtk-peer to implement awt and swing then remove the
–disable-gtk-peer option to GNU Classpath configure.

Thanks for your reply Xerxes. I made 2 different changes while compiling GNU
Classpath. Both compiled successfully.

1. ./configure --host=arm-xscale-linux-gnueabi  --prefix=/usr/local
--disable-examples --with-x --disable-qt-peer --enable-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.gtk.GtkToolkit

After transferring the above compiled gnu classpath and jamvm to the device,
when I run a sample swing application, it shows nothing. When I did verbose
it loads and links so many classes and finally stops with following two
lines

[Loaded gnu/java/awt/BitMaskExtent from
/usr/local/share/classpath/glibj.zip] 
[Linking class gnu/java/awt/BitMaskExtent]


2. This was another variation which I tried in which I disabled gtk and
default toolkil I gave of X.
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 

After transferring the above compiled gnu classpath and jamvm to the device,
when I run a sample swing application, it gives me following error:

Exception in thread "main" java.lang.ExceptionInInitializerError

I am still not able to figure out what I am missing. Can you please give me
further pointers to that I can move in correct direction.

Thanks

The error above at
gnu.java.awt.font.OpenTypeFontPeer.<clinit>(OpenTypeFontPeer.java:93) if you
look at the source code for gnu classpath you can see that the null pointer
is caused by some issue for gnu classpath to locate the font.properties
resource file, that contains a list of system fonts to use for awt and
swing.
Most likely you have missed to copy some required file to your arm board or
the classpath do not contain the jar containing the
resource/gnu/java/awt/font/fonts.properties .
Remember that custom gnu classpath configure setups with lots of --enable
and --disable options are naturally much less tested by other gnu classpath
developers compared to using the default settings without any extra --enable
or --disable options.

None of these errors looks to be JamVM related therefore I recommend you to
ask classpath swing setup and configure questions on the GNU Classpath
mailinglist:
http://savannah.gnu.org/mail/?group=classpath

You may want to try run JamVM in combination with the OpenJDK classes that
also provide AWT and Swing support.

Cheers
Xerxes

Hello Xerxes,

Thanks a lot for your inputs. I have posted my query on gnu classpath
forums. Meanwhile can you please direct me towards a place from where I can
find openjdk classes source code which I can cross-compile for my arm xscale
machine.

Thanks,
Aditya

You can cross-compile OpenJDK 6 + jamvm and OpenJDK 7 + jamvm by using OpenEmbedded oe-core+meta-java
Woglinde is the active maintainer of the meta-java cross compile scripts.
Build instructions: https://github.com/woglinde/meta-java/wiki

To find out more about the OpenEmbedded cross compile infrastructure read:

Dear Andrews,

Thanks for your reply. I searched for the files which you asked in your
reply. All those files are present in our port on the device. Still no luck
