to add to Sascha's comments: if you are just trying to cross-compile 
some self-contained Java code, the C backend is already superior to the 
Objective-C backend. We are still shaking out some bugs with 
multi-threading and exception handling, but by and large it is usable. 
What will need more work is the conversion of the iOS API for the C 
backend. Here the Objective-C backend is still more complete.

I will send updates over the mailing list when we reach certain milestones.

Re: [xmlvm-users] Could not find target by name: android-on-iphone

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

there is no target android-on-iphone anymore. Please consult the 
documentation:

http://xmlvm.org/documentation/

In particular look at sections 4.2 and 6.1. They describe what you were 
trying to do.

That is correct. The reason the documentation doesn't mention C or Posix yet
is because these targets are still in development and not yet recommended
for general use, although you are of course happy to try them out.

Yes so with the move to C one of the things we do is cross-compile most of
Harmony, which should enable you to use most classes from the standard JDK.

The C target will just take every class you feed it and spit out c files.
Not more and not less. The POSIX target does more. It's goal is to spit out
a whole project that contains all JDK dependencies that your app needs and a
MakeFile that you can simply use to build your app. If you want to target
the iPhone, then there is one more target (or for you it's actually the only
one) that is important: iphonecandroid.

Once these targets are more complete and stable, we will most deprecate the
ObjC targets and move everybody to the C backend.

I leave it to the people actually working on these parts right now to reply
with more detail, but I know that the C backend will probably not enable
this quite yet. I know that Wolfgang is working on getting networking going
right now. I don't think we touched audio processing with the C backend yet
at all.

With the ObjC backend you might have more luck, but again I leave it to
Arno, Wolfgang and Panayotis to give the details. But at least we were able
to to cross-compile apps with networking and audio in the past. I guess it
depends on the exact API you are using and whether the ObjC compat lib
supports those.

[xmlvm-users] Advice

[Andrew H. <a.s...@gm...>]

I've been in the xmlvm mailing list for a while.

Im am now starting a port of a complex standard java application to the
iphone using xmlvm.

It does currently run on android but most of it was developed under linux
(Just added a GUI for the android)

After reading the mailing list and the documentation I'm a bit confused.

The documentation doesn't mention the C or posix targets. The mailing list
suggests using the posix target as it has translated most of Harmony.

Posix sounds great as when I last tried this with the Obj-C version it had
too many standard bits missing (System.err, java.util.Hashtable ...)

Now for the questions.

   1. What is the difference between the posix target and C target
   2. What target would the group recommend for porting a standard java
   application with minimal GUI's, lots of complex multi-threaded algorithms,
   networking and audio processing ?

Any assistance/advice greatly appreciated.

I'm try to build an xcode project from a fresh android project.


I did the following:

Re: [xmlvm-users] InvocationTargetException

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

Hi,

xmlvm is cross compiling the .class bytecode files and not the .java source
files. So --in should point to the directory containing them. Does src/java
contain them in your case?

[<xm...@pa...>]

Hello, well after a lot of searching futzing and banging my head against
the wall  I finally got it to compile, and got it setup as an external
tool. inside eclipse and I'm looking at your demo android projects and
i can't figure out what I'm supposed to do to make it into an iphone
app  your presentation on what's going on under the hood and what is
possible with your system was nice and certainly is something I'd be
very interested in  not having to learn yet another programing language
to bring my android apps to the iphone market.  still I have no idea how
I actually tell it to do the deed.

so can you give me a bit more clear instructions?  I know how to make
android apps in eclipse and how to use eclipse to export them to apk
files
but I really don't know a whole lot about eclipse outside strictly using
it for android app development. also I haven't set about learning java
or c  before taking on this project. and you did say in your
presentation that shouldn't be necessary.  yet your instruction seems
to imply that I should know how to do a ton of stuff from the command
line.  which I have no clue how nor did I need to learn when i was
making my android app.  I did gleam from your video that your system
runs off the finished apk from my android code instead of using the
source directly.  I make those using the export function of eclipse how
though do I put yours in to the mix? or what am I missing?

I think you need to add xmlvm.jar to CLASSPATH when you try to run 
ihelloworld.jar.

Re: [xmlvm-users] Problem with java application execution

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

Hi,

The easiest way to run the iphone demos is to use the same ant-script you
use to build them.

Building ihelloworld (e.g. the portrait version):
cd [xmlvm_root]/demo/iphone/ihelloworld/portrait
ant

Running ihelloworld:
cd [xmlvm_root]/demo/iphone/ihelloworld/portrait
ant run

The ant script does a lot of steps in that target to launch the application
in the Java iphone emulator. You can take a look at the script and reproduce
those steps if you don't want to launch through ant.

Markus

[xmlvm-users] Google Android tools & XMLVM

[Panayotis K. <pan...@pa...>]

Dear all!

It has been reported that the latest version of Google tools for the Android platform are incompatible with the XMLVM ant targets.
This is really the case, so a new patch is now committed to the SVN repository which fixes this problem.

Unfortunately this update will break the old development tools. If you wish to update to the latest XMLVM version, it is required to update to the latest version of Google tools also.

Apart from this problem, the latest version of XMLVM supports MapKit for iOS and some other random fixes (i.e. projects are now more easily relocatable).

Sorry for the inconvenience!

[xmlvm-users] Using Auto-gen tools to build platform extensions .aka. Plug-ins ?

[Jeff P. <jcp...@ro...>]

Hello,
Have been watching your progress for sometime.  Never even got a
distribution till today.  The reason being if SQLite was not available, then
there is no point. 

I have also used JavaCL, which is built up around running opencl.h through a
program called JNAerator ( http://code.google.com/p/jnaerator/).  This
produces a .java file similar to the ones I see in ³plugins² directories.
Here is one based on a SQLite header file (
http://code.google.com/p/nativelibs4java/issues/attachmentText?id=47&aid=-47
83055163521202661&name=Sqlite3.java&token=1f1d1e7779a2abd4ad5fec4a43b618b0 )

This class calls some BridJ  classes & binaries (
http://code.google.com/p/bridj/).  BridJ & JNAerator are both written by
Olivier Chafik, my personal hero.  BridJ is BSD, so licensing is a
non-issue.

My thought was to try to get the Bridj part into the objc directory of the
plugin.  If this can be made to work, maybe the iphone compatibility layer
could be computer generated too, since I the plugin directory structure
there.  This could all too much work.  I do not know, but if not you might
be able to ditch hand building bindings code, outside of Harmony, anyway.
Wait does harmony use .h files?

Please feel free to tell me I am whacked,

That does make sense, if you want to have it somewhere else. I think .cache
is already on the .svn ignore list, if not it should be. So you cannot
accidentally submit it.

Apart from that feel free to send me a change for review which lets you
specify the cache directory location.

I believe caching is fine, as long as it is not in my way.
Keeping it with the name ".cache" is a good naming convention of course, but there should be at least a way to redirect this to another location, probably with a command line argument ? or... use some other heuristics where to save it?

Keeping temporary garbage in the root tree of a project I don't think it is a good idea. There should be a way to redirect this (useful) garbage to a place which can be easily collected :)

Well, it's not really hidden. It's just that some operating system or file
browsers decide to hide files and folders that start with a dot :)

I think it's fine the way it is. The purpose of this directory is that
normal XMLVM users don't have to worry about it at all. Naming it .cache is
a convention I have seen in other tools as well.

Btw, you can also switch of caching, if you want to, using the --no-cache
option with XMLVM. It can help in certain situation, e.g. if you make
changes to the style sheet. Again, a normal user doesn't need to care about
that flag at all.

Although in general I understand the reason for being hidden, I believe that there should be a way to make it "visible" to the user.
At a minimum I believe that this folder should not be hidden, so that the user might understand what is happening.
If this is not elegant enough, we can make other optimizations, like produce in the tmp folder, or specify a target directory where all possible temporary/intermediate files could be stored.

What do you think?

Re: [xmlvm-users] .cache directory

[Sascha H. <sa...@gm...>]

That, too but since then it's become a cache for xmlvm resources as well to
speed IP execution.

i think that in the past it was used to save backups of your wrappers
before all the injection of the old wrapper code into the newly
generated wrappers happens.

Probably then, should it moved inside the "build" directory?
It will be less file/directory pollution in the main directory and it will be cleaned properly with most "clean" ant tasks :)

It holds intermediate data to speed up consecutive XMLVM runs. You can
safely remove it at any time.

[xmlvm-users] .cache directory

[Panayotis K. <pan...@pa...>]

Good day!

What is the purpose of .cache directory?
Can be safely deleted after cleaning a project?

Re: [xmlvm-users] Using XMLVM to generate a Cocoa library

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

it sounds like the categories are not defined for the Cocoa classes. I'm 
assuming that you are linking in all files that are contained in 
src/xmlvm2objc/compat-lib/*, correct?

If the code you are compiling is just plain Java code, I would suggest 
you use the new C backend. Try --target=posix and have a look at the 
code. One benefit is that it pulls in cross-compiled versions of Apache 
Harmony, so the J2SE API is much more complete than what we have right 
now on the Objective-C side.
