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

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hello Panayotis

Sorry, but I'm too blind to see it. I can't find any solution for my 
problem in the documentation. The only thing that I can find is the way 
how to compile Java-classes into Objective-C and this is exactly the way 
I've done it.

Perhaps my problem was not described clear enough:
The process to cross-compile Java-classes into Objective-C-classes works 
absolutly fine. Theres no error message or something like that. But I 
don't know how to make a project out of the cross-compiled files on 
Mac-site. The result of cross-compiling the classes is a folder full of 
.m and .h-files. So can you tell me how I can get a complete project out 
of these files? And it's not an iPhone-app what I want to create, if you 
think so.

If there's a fitting part in the documentation, so I wasn't able to find 
it. So can you please give me another hint? ;)

Thank you and sorry to cause you inconvenience.

Miggi
