Executable size #64

Closed joprice closed 8 years ago

Running the 'hello' example gives me an executable of 76M. This doesn't give much room until apple's 100m wireless download limit. I turned on the aggressive treeShaker, but I got the exact same executable. Is the treeShaker not used when running the iphoneSim task?

If you are running in 32bit mode (which is default IIRC), the tree shaker does not run "due to bug in linker", this is a RoboVM bug, you should find that in the logs. That, combined with heavy scala-library contributes to pretty big executables. You can always use proguard though.

That tip helped!

Perhaps this should be mentioned in the readme?

Do you know of an example sbt-rovovm ios proguard project?

Darkyenus commented 8 years ago

I can't think of any, but it shouldn't be hard. Simply configure sbt-proguard plugin and plug it into the RoboVM plugin with something like:

robovmInputJars := (proguard in Proguard).value
