I'm trying to cross-compile some code to the iPhone. One of the classes I need among others is java.math.BigInteger. I see there is a subset of the Java standard libraries already cross-compiled to Objective C. Is the recommended approach just to take the java.math.BigInteger class and cross-compile it manually. I'm trying to understand what is included vs. what I need to do manually? Thanks! |

Would it be sufficient in the meantime to just try to cross-compile BigInteger and all of it's transitive dependencies? I'm using a library that has this dependency on BigInteger among other things.

You can try, but my fear is that "transitive closure" will result in half of the JDK. At that point you will most likely run into deficiencies with the Objective C backend as well (which we don't have with the new C backend). Right now I am stalled with the C backend until we have sorted out the dependency problem.

We pursue the idea of cross-compiling the JDK to achieve better API coverage. One problem you will encounter is the dependencies within JDK: if you reference one class (such as BigInteger) you inadvertently pull in half the JDK because of all the dependencies. I know I have saying that we are working on this for the past three months without anything happening, but I hope we will make progress real soon.

So, are you saying that the current back-end may not be sufficient to support cross compiling this particular class until the new back-end is finished? Currently, I'm more worried about the functionality more than extra dependencies. Thanks again!

I believe it is easier to just create a wrapper (like the other java.*.* objects) in Obj-C and simulate more or less the functionality. A simple way to do this, if you really don't care about accuracy, is use a double (or long long) number to do the mathematics in the Obj-C world. |
