Re: [ALACPP] compilation error

[Frank <fmoody-ug-alacpp@xxxxxxxxxxx>]

	Throwing a pair of parens at the end of the "throw MyException;" line seems to solve the problem.  I think the issue is that the parameter to the throw is actual data where MyException is a classname.  The int(1) (and the MyException()) bring a temporary variable into existence which is apparently valid.  I think...  But my books are still packed up from my move...
