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).
