[xmlvm-users] Cross-compiling Java-classes into Objective-C

[Miggi <mig...@go...>]

Hi there

I've some problems with cross-compiling Java-files into Objective-C. 
When I tried it, I got a .h and .m for every .class file. That's ok. But 
when I tried to build it in Xcode, I got several errors because things 
like java.lang.Object or java.lang.String couldn't be found. What did I 
wrong that such simple and basic classes weren't found?

The way I've cross-compiled the classes were:
     java -jar <path to xmlvm.jar> --in=<path to folder with java-files> 
--out=<path to an empty folder> --target=objc

Do I have to add something? Or isn't it possible to copy the resulting 
files in an empty Xcode-project and to build it?

Thanks for your answers.

I believe if you have a look at the documentation 
http://www.xmlvm.org/documentation/
you will be able to solve your problem.

note that --target=objc only cross-compiles to Objective-C, nothing 
else. The dependent classes (such as the ones you've mentioned) will not 
be copied to the --out directory. The other targets (such as 'iphone') 
will do this.
