Merci Laurent. That's progress. I generated a BridgeSupport file.
Now, I'm getting this: >> theme = CPTheme.themeNamed(KCPDarkGradientTheme) => #<CPDarkGradientTheme:0x200621300> But now: >> z = CPDecimalFromFloat(4.1) Assertion failed: (size > 0), function convert_type, file compiler.cpp, line 5803. Abort trap CPDecimalFromFloat and friends are not inline functions so I don't need to generate a dylib file, as far as I can tell. And: >> xLow = 0.0 => 0.0 >> xLow = NSNumber.numberWithFloat(xLow.to_f).decimalValue => #<NSDecimal:0x20055fc60> >> fDays = 398.0 => 398.0 >> fDays = NSNumber.numberWithFloat(fDays.to_f).decimalValue => #<NSDecimal:0x2005ebe60> >> xrange = CPPlotRange.plotRangeWithLocation(xLow, length:fDays) Assertion failed: (size > 0), function convert_type, file compiler.cpp, line 5803.
