Re: [xmlvm-users] Status of the project

[Kensuke M. <mat...@ki...>]

Hi,

http://xmlvm.svn.sourceforge.net/viewvc/xmlvm/trunk/xmlvm/lib/redlist.txt?revision=2338&view=markup

'redlist.txt' is a list of unsupported classes.
It would be help to estimate the amount of change to convert your project.

e.g. org.apache.commons.logging.Log isn't supported yet.

Re: [xmlvm-users] Problem with Cross Compilation using XMLVM

[Nikolai P. <ni...@np...>]

Hi John,

You should put un argument to let java use more memory. Try executing the same command, but with "-Xmx2G" argument:

java -Xmx2G -jar xmlvm.jar --in=/HelloWorld.class --target=iphone --iphone-app=TheApplication

Re: [xmlvm-users] Problem with Cross Compilation using XMLVM

[Markus N. <mar...@gm...>]

Hi John,

Several issues with what you are trying to achieve:

1. For the out of memory exception just add increase the heap space of the
vm like this:
java -Xmx 2G -jar xmlvm.jar --in=/HelloWorld.class --target=iphone
--iphone-app=TheApplication

2. If you want to cross-compile to the iPhone you can't just simply use a
Java program with a main
method as entry point but you will have to extend UIApplicationDelegate
instead. Check out the tutorial
under http://xmlvm.org/tutorial/ which steps you through creating a simple
HelloWorld and also
includes a ton of other example apps

Cheers,
Markus

[xmlvm-users] XMLVM and some OpenGL methods missing

[Carlo B. <car...@gm...>]

Dear all,

I am currently trying to cross compile my 3D game engine from Java (nearly
pure - platform specific code is separated) to Iphone ObjC. Things seems to
go well, but not all the Opengl methods are available in the GL header
file, for ex. GlNormalPointer. Also Direct Float Buffers are throwing an
exception of a Red class under Xcode, I switched to Non Direct Float
buffers. I would be interested in adding the missing wrapped opengl methods
but I do not know exactly the steps to take.
It would be nice if you could explain to me these steps, I would of course
supply a new patch if it is working well.

Thank you in advance,

Best regards,

Carlo

[xmlvm-users] OpenGL support in new IOS API

[JR S. <sc...@we...>]

It appears that OpenGL support isn't complete in the new IOS API. From 
what I can tell, not many changes would be needed:

0) The org.xmlvm.iphone.gl.GL wrapper class can still be utilized, 
unmodified, even in the new IOS API since it is a pure static warpper of 
OpenGL calls.  In other words, since nothing derives from NSObject, it 
does not "contaminate" the new API.
1)  A analogous UIViewGL class is needed to change the backing layer 
type to a CAEGLayer. This seems to be the trickiest part to me, since 
this requires making a new class and wrapper class.
2)  A few unimplemented methods (renderbufferStorage and 
presentRenderBuffer) need to be implemented natively.  This appears 
really easy, as it seems you an use the existing org.xmlvm.iphone.* 
native code with little or no modification.

Has anyone tried this?  Step 1) seems to be the trickiest part, at least 
for the uninitiated.  If someone is willing to do 1), I will give 2) a 
shot and be happy to forward on the results / patch.

[xmlvm-users] Status of the project

[Victor S. <vic...@gm...>]

Hi All,

I'm  developer of opensource app
http://github.com/osmandapp/Osmand(basically mobile navigation ). I
would like to know how feasible will be
to convert the project to iOs using xmlvm?
I'm fine with contribution and changing code from Android/Java approach to
compliant library. Application itself is quite simple however it consists
of >100K  lines. It uses threading/computation/IO/and custom UI heavily.

Where also I could find tutorial how to configure Android project to work
with llvm?

Many Thanks,
Victor

Re: [xmlvm-users] java.nio.ByteOrder unimplemented?

After removing the java.nio.ByteOrder class from the redlist, it appears 
to work without any issues. Since this is a relatively important member

Re: [xmlvm-users] java.nio.ByteOrder unimplemented?

[Markus N. <mar...@gm...>]

Hi,

java.nio.ByteOrder is on XMLVM's redlist (not sure why it was added there).
I don't know why it was originally added there.
To include it in the cross-compilation simply remove it from the
/lib/redlist.txt and give it another shot.

In case you get new errors after that (e.g. unimplemented native methods,
etc.) let us know.

[xmlvm-users] Performance impact of "synchronized" methods with XMLVM

[JR S. <sc...@we...>]

For the benefit of the community, I post the following observation:

With XMLVM code, the use of "synchronized" methods results in a massive 
performance hit as compared to unsynchronized methods.  This can crop up 
in many cases, e.g. the use of the old fashion "Vector" or "Hashtable" 
java classes (which are both synchronized). Replacing those by the 
newer, unsynchronized ArrayList / HashMap classes results in a huge 
(100-1000x!) performance increase in these functions.

While there is also some performance hit from synchronization in the 
corresponding "native" Java code, it is FAR more modest.

[xmlvm-users] java.nio.ByteOrder unimplemented?

[JR S. <sc...@we...>]

It appears that the java.nio.ByteOrder class is not implemented in the C 
interface.  This seems odd,as the rest of the java.nio.* class is 
entirely present and functional.  This means that it is impossible to 
switch the byte order from the default BIG_ENDIAN.

Is this an intentional omission (i.e. only one byte order is 
implemented)?  Is there an easy work around?  It would seem that the 
ByteOrder class should have been translated along with the rest of the 
package, automatically!

AFAIK iOS does not support animated GIFs. This page describes how to do 
this under iOS:

Note that you need the new C backend if you want to do this with XMLVM 
(look for --xmlvm-new-ios-api in this form to see how to use the new C 
backend).

Anybody tried using an existing animation as such:

UIImageView img = new UIImageView(new CGRect(5, 150, 300, 140));
img.setImage(UIImage.imageNamed("bob.gif"));

I'm new to XMLVM and would like to learn how to deploy simple animations.
bob.gif runs as an animated gif in the browser.
It works fine if bob.gif is a still image rather than animation.
Any other UI api available to run the animation?

Hi,

Is there anyone who working on "Accenture XMLVM enhancements for model-only translation"?
http://xmlvm-reviews.appspot.com/216001/

I think this patch can be split into three independent patches
A) model-only translation
   1, 2, 3
B) bug fix or lack of features.
   4, 6, 7, 8
C) mobile Qooxdoo
   5

I'm interested in A and B.

Re: [xmlvm-users] Proper method for including native code

[Arno P. <ar...@pu...>]

those comment markers are always emitted but only used for skeleton 
classes. For skeleton classes, XMLVM will inject the implementation 
between those comment markers into the generated code. This is meant as 
an internal mechanism and shouldn't be used by a developer.

You can mark methods as 'native'. In those cases XMLVM will not emit an 
implementation and you can link a separate file to your executable that 
provides the implementation of the native methods. In this case you have 
to comply to XMLVM's name mangling and passing of parameters. As a first 
step, add a static native method to a class and compile this with XMLVM. 
The linker's unresolved external error will guide you what to do.

[xmlvm-users] Proper method for including native code

[JR S. <sc...@we...>]

I am curious as for the recommended approach for including native C/ObjC 
implementations of Java functions, as is done for many of the 
XMLVM-included classes.  I am starting with an XMLVM skeleton project 
and using ant. The ant "run" target generated C code from Java.  But 
modifying the resulting code in Xcode between the 
//XMLVM_BEGIN_IMPLEMENTATION
//XMLVM_END_IMPLEMENTATION,
the resulting code is lost / overwriteen upon the next ant "run".  I see 
that XMLVM contains a "gen-c-wrappers" target which implies it preserves 
changes, but modifying the build.xml to use this target didn't see to 
help either.

Any references / suggestions would be appreciated.
