[MacRuby-devel] CorePlot success?

[Laurent Sansonetti]

Hi Russ,

Could you try MacRuby trunk? (Try the latest nightly build: http://www.macruby.org/files/nightlies/)

I changed the compiler to recognize C-style arrays in structs and I'm believe it's the problem you're hitting.

Also, I believe that gen_bridge_metadata will generate 32-bit metadata by default, and I suppose you run MacRuby in 64-bit mode (as it is the default on 64-bit hardware). You may want to pass the --64-bit argument to the generator.

This could explain why MacRuby cannot use the CPDecimalFromFloat() C function or the kCPDarkGradientTheme C constant (note that it must be called KCPDarkGradientTheme from MacRuby, as constants must always start with a uppercase letter).
