property dynamic getter/setter issue on Android

[Aleksandar Bogdanovic]

Hi, all.

I'm playing with HAXE these days. Trying to make cross-platform library and I need for it dynamically added setters and getters.

As I see it works on Flash and Windows but when I try to compile for Android I get following error:

./src/be/zajac/test/Test.cpp: In member function 'virtual Dynamic be::zajac::test::Test_obj::__Field(const String&, bool)':

./src/be/zajac/test/Test.cpp:307: error: operands to ?: have different types 'Dynamic' and 'int'

Which is related to this line:

public var backgroundColor(dynamic, dynamic): Int;

But when I replace Int with Dynamic it passes compilation and it works.

As this is library I want to limit 3rd party to set other values than Int.

I was digging deeper and figure out why is this error raising. My backgroundColor variable is compiled to Test.h file as this:

int backgroundColor; /* REM */ 

Dynamic get_backgroundColor;

Dynamic set_backgroundColor;

And in Test.cpp getting value from backgroundColor is compiled like this:

if (HX_FIELD_EQ(inName,"backgroundColor") ) { return inCallProp ? get_backgroundColor() : backgroundColor; }

so VisualC++ do not care about data type returned after "?", but Android NDK is strict in this case.

Is there any way to solve this situation? I need interface to stay as it is.

Hi,

This looks like a bug in the cpp backend that can't be resolved without a compiler update.

You could work around it by not using (dynamic,dynamic), like:

public var backgroundColor(_getBG, _setBg): Int;

public var get_backgroundColor:Void->Int;

var backgroundColor:Int;

inline function _getBg():Int { return get_backgroundColor(); }
