[MacRuby-devel] CorePlot success?

[Laurent Sansonetti]

Hi Russ,

I suspect this CorePlot framework does not include a BridgeSupport file. 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).

You can try to generate a BridgeSupport file using gen_bridge_metadata(1). Check out the end of the man page for examples. The generated file should be installed within the framework.
