Re: [xmlvm-users] Problem while cross-compile from android to iOS

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

you are making use of an external JSON library that XMLVM doesn't know 
about. If that library is bundled as a .jar file, you can try adding it 
via --in. You should also look at the Android API that is supported by 
XMLVM (check xmlvm/src/android2iphone).

That's probably a better question for tigris.org, but make sure you have
administrator rights & since you're on a Mac, make sure you have JavaHL
setup:

downloaded from http://www.open.collab.net/downloads/community/ the package
will not install after accepting the license agreement.

After that there is only one item: Install for all users ... which is

Any guidance will be appreciated.

Re: [xmlvm-users] Problem while cross-compile from android to iOS

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

please note that XMLVM requires .class files as input; not .java files. 
The directory you reference with --in= needs to contain .class files. 
Take a look at the slides in xmlvm/doc/slides (towards the end of the 
slides) that explain how to import an Android project as a Java project 
and link it with XMLVM. If Eclipse should show any errors, you won't be 
able to use XMLVM to cross-compile your app.

[xmlvm-users] Problem while cross-compile from android to iOS

[Rudolf S. <sch...@ha...>]

Hello,

I tried to cross-compile an android project to iOS. My first try was to use the following command for an existing android project created by eclipse "xmlvm --in=Test/ --target=iphone --lib=android --iphone-app=Test2" where I got a warning for every .java, .xml and .png file like these:

[…]
[03/30/12 13:08:08.745]  WARNING: Unable to create InputProcesses for input: […]Test/src/de/Test/TestActivity.java
[03/30/12 13:08:08.745]  WARNING: Unable to create InputProcesses for input: […]Test/res/values/strings.xml
[03/30/12 13:08:08.745]  WARNING: Unable to create InputProcesses for input: […]Test/res/layout/main.xml
[03/30/12 13:08:08.745]  WARNING: Unable to create InputProcesses for input: […]Test/res/drawable-mdpi/ic_launcher.png 
[…]

In the created Xcode project, I got a message "Update to recommended settings" 
"Target '../Test2' - Upgrade Compiler configuration to LLVM"
"Project 'Test2' - Upgrade to latest Project Format'

After that, I got some errors. 4 times in the file "java_lang_String.h "Redefinition of 'java_lang_String' as different kind of symbol" at the line "typedef NSMutableString java_lang_String;"
and one time in the file "org_xmlvm_iphone_NSObject.h" "Redefinition of 'org_xmlvm_iphone_NSObject' as different kind of symbol" at the line "typedef NSObject org_xmlvm_iphone_NSObject;"

I deleted these lines for test and got the next error in "java_io_ByteArrayOutputStream.h" "Cannot declare variable inside @interface or @protocol" at the line "static int const DEFAULT_CAPACITY;"



So I thought cross compiling a project defined by eclipse does maybe not work yet and I started the next try by migrating the eclipse project using "xmlvm --skeleton=android:migrate --out=../Test" to a xmlvm android project where I got the following warnings:

[03/30/12 12:33:25.045]  WARNING: Using Test as application name
[03/30/12 12:33:25.052]  WARNING: InputProcess.getOutputFiles(): Input File is null.

The resulting project does not contain the "src", "bin" and "res" folder.

Can somebody help me?

Best regards,
Rudolf Schillack

Re: [xmlvm-users] Using the posix backend

[Markus H. <ma...@ti...>]

Seems you are trying to do UDP stuff. I have implemented some UDP stuff in this patch: http://xmlvm-reviews.appspot.com/136001/

It is not in the mainline yet, and may have some errors, but you could try to apply it to the current trunk version of xmlvm. Unfortunately I have currently no time to complete the patch. :(

Markus

Re: [xmlvm-users] Using the posix backend

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

look at src/android2iphone to see which Android classes can be 
cross-compiled to iOS.

As for standard J2SE API, XMLVM cross-compiles Apache Harmony. We have 
deemed some classes as not required for iOS. We call these "red 
classes". You can see a list of those classes in xmlvm/lib/redlist.txt. 
If you happen to need a class that is on the red list, simple remove it 
in redlist.txt.

You ran into an unimplemented native method. Although we cross-compile 
Harmony, some classes require access to the native layer (in your case 
you are trying to create a socket). That code is in 
xmlvm/src/xmlvm2c/lib/native. You would have to provide a C 
implementation for the API you need.

Re: [xmlvm-users] Using the posix backend

Is there a list of the Android/Java classes that are supported by the various backends anywhere?

Following your advice, I have managed to get the Boehm GC installed, and a posix project compiled to an executable. However, when I run it, I get the message:

XMLVM Error: Unimplemented native method: (org_apache_harmony_luni_platform_OSNetworkSystem_createDatagramSocket___java_io_FileDescriptor_boolean):../src/native_org_apache_harmony_luni_platform_OSNetworkSystem.c:447

Re: [xmlvm-users] Using the posix backend

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

try --target=iphonec (which will use the C backend instead of the 
Objective-C backend). The C backend cross-compiles Apache Harmony so 
your chances of making this work are higher. The older Objective-C 
backend manually implemented a few J2SE classes (see 
xmlvm/src/xmlvm2objc/compat-lib/objc).

Re: [xmlvm-users] Using the posix backend

[Bruce J. <bru...@go...>]

Hi Arno

Thanks for your help. In a seperate thread you said that:

Note that XMLVM only supports a subset of Android API that can be 
cross-compiled. Take a look at xmlvm/src/android2iphone. If you are 
using API that is not in that folder, your app won't cross-compile.

When I open the generated project using the out=iphone switch in XCode, I get a collection of compilation problems relating to header files missing. All of these are within the standard java.* namespace, for example:

#import "java_net_InetAddress.h"

Is there something else I need do when I build the project, or something else to setup in Xcode?

Thanks

Bruce

Re: [xmlvm-users] NSData Bug

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

I think that code is correct. If you look at the documentation of 
InputStream.read(byte[]) you will see that if will read at most the 
length of the array. That is that the i == READ_BUF_SIZE is for: it 
indicates that there is potentially more data to be read.

But to mention something else: the code you are referring to is the Java 
implementation of class NSData. This code belongs to XMLVM's Java 
emulator for iOS (meaning you can run a Java-based iOS application on a 
JVM). That was more an experiment and we stopped adding functionality a 
long time ago because we would have to re-implement iOS in Java (which 
is clearly out of scope). Note that that Java implementation you are 
seeing is *not* used during cross-compilation.

Re: [xmlvm-users] Using the posix backend

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

XMLVM bundles a garbage collector pre-configured for iOS. For all other 
platforms (i.e., Posix) you need to download and install the Boehm GC 
yourself. Note that the Boehm GC recently moved to github:
http://www.hpl.hp.com/personal/Hans_Boehm/gc/

Re: [xmlvm-users] (no subject)

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

unfortunately the documentation is out of date. The target 
android-on-iphone is deprecated. You should use --target=iphonec (to use 
the C backend) or --target=iphone (for the Objective-C backend) in 
conjunction with --lib=android.

Note that XMLVM only supports a subset of Android API that can be 
cross-compiled. Take a look at xmlvm/src/android2iphone. If you are 
using API that is not in that folder, your app won't cross-compile.

Re: [xmlvm-users] XMLVM opengl

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

sorry for the slow response. XMLVM supports some OpenGLES API for iOS. 
Look at class NeHeLesson4 in xmlvm/demo/iphone. Note that XMLVM's 
Android Compat Lib (that is used when cross-compiling from Android to 
iOS) has no OpenGLES support.

Thank you, thats great. If I am actually wanted to end up with a library that I can use in an existing iOS application, is this the ight way to go, or should I just set the --out=iphone ?

Thanks

Nothing in the documentation tells me I need to have anything else installed on my system in order to build for a posix backend, but obviously I'm missing something (probably the boemgc library?) or I don't have a path to appropriate headers set up.

Re: [xmlvm-users] Using the posix backend

[Paul P. <bay...@gm...>]

You are correct.  You can find the instructions to install the boehm GC in
the comments at the beginning of "xmlvm/var/posix/Makefile".

Thanks,

[xmlvm-users] Using the posix backend

[Bruce J. <bru...@go...>]

Hello there

I have a simple Java library that I use in an Android application and I would like to convert it using xmlvm using the posix backend on MacOS X 10.6.

I have built and installed xmlvm as described in the docs, and that all looks good. My java classes are in a directoty called java, and I want the output in the directory src.

When I enter:

xmlvm --in=./java --out=./src --target=posix

…I correctly get the directories src and dist created under src. diet contains just one file (Makefile) while src has a whole pile of .c and .h files as I would expect.

If I then go into dist and type:

make

… I get the following message:

mkdir -p build/
mkdir -p build/obj/
gcc -w -std=c99 -DALL_INTERIOR_POINTERS -DGC_THREADS -DTHREAD_LOCAL_ALLOC -DPARALLEL_MARK -DUSE_MMAP -DUSE_MUNMAP -DNO_DYLD_BIND_FULLY_IMAGE -I../src -c ../src/com_pure_media_MediaStore.c -o build/obj/com_pure_media_MediaStore.o
In file included from ../src/com_pure_media_MediaStore.c:1:
../src/xmlvm.h:51:16: error: gc.h: No such file or directory
make: *** [build/obj/com_pure_media_MediaStore.o] Error 1

I can see what's happening here, but I'm not sure what I need to install in order to get gc.h. Nothing in the documentation tells me I need to have anything else installed on my system in order to build for a posix backend, but obviously I'm missing something (probably the boemgc library?) or I don't have a path to appropriate headers set up. 

Can anyone help/advise?

Thanks

[xmlvm-users] (no subject)

[Tymen S. <tym...@it...>]

I encountered the exact same problem as the previous post (as written below).

"
 For some reason 'android-on-iphone' is not an acceptable xmlvm target for me.
 
 Why is this?

 Did I build xmlvm without the right path to Android? Has anyone else seen this?

 I am on Mac OS 10.7

"

In the documentation it states that the ' android-on-iphone'  target should be used to cross-compile an
Android application to the iPhone where the Android compatibility library will be copied to the output
directory.

"
xmlvm --in=/foo --target=android-on-iphone --iphone-app=TheApplication
Same as the previous example, but will also copy the Android compatibility library to the output directory. This effectively allows Java-based Android applications to be cross-compiled to the iPhone.
"

Anybody who can help with this issue?

Thanks in advance.

[xmlvm-users] NSData Bug

[Tim C. <ti...@vi...>]

Hi,

I am trying to consume a JSON response, however, NSData byte array size is only 26. I saw there was an earlier discussion about this, but no resolution.

When reviewing the code I see this logic:

	do {
                byte[] buf = new byte[READ_BUF_SIZE];
                i = in.read(buf);

                if (i > 0) {
                    l.add(buf);
                    bytesRead += i;
                }
                
            } while (i == READ_BUF_SIZE);

How is it possible that (i == READ_BUF_SIZE)? In other words read the input stream while i = 32767 - this will end after the first try. I can see that my InputStream does contain all of the data but the readData method only returns a 26 character portion.

I am fixing this for my own immediate needs but in the meantime I wanted to understand if I was missing something since I would assume this to be a fundamental need for a lot of apps???

Here is my fix for the time being:

private void readData(InputStream in) {
        data = new byte[READ_BUF_SIZE];
        
        try {
            int offset = 0;
            int numRead = 0;
            
            while (offset < data.length && (numRead=in.read(data, offset, data.length-offset)) >= 0)
                {
                offset += numRead;
                }

            in.close();
        } catch (IOException ex) {
            // Do nothing
        }
    }

[xmlvm-users] XMLVM opengl

[Joe L. <joe...@gm...>]

Hi,

I was wondering the status of OpenGL support in XMLVM?  I have a 3D game I
am developing for android that is designed to be platform independent.
Currently it should run on a desktop, applet, through javascript (gwt).  I
am thinking about creating an iphone version utilizing XMLVM, but before I
dive in I was wondering what everyones thoughts are on OpenGL ES in XMLVM.

Regards,
Joe

Is there some small set of native methods that we would need to implement, or would it be necessary to provide a complete implementation of native AWT peers (as I understand it is done for desktop Swing applications).

My understanding from Swing, is that it only needs a small subset of AWT to be ported and then everything is drawn by the library itself.
This "small" subset though is not so small, because all native 2D-3D methods should be implemented, as well most basic peers (like windows and awt canvas)
