Hi again, I've digged a bit further on my problem. Compiling the vala code to C code, showed a temporary variable which was a float. Changing this variable to a double fixes the problem of the 'random' value. I've attached a minimal sample vala program, and diff to change the resulting c code. (all with vala 0.7.5) This still leaves me wondering why i need to box a double to use it as a generic type, while an int can be used just like that. Kind regards, Thomas Meire On Fri, Aug 7, 2009 at 8:53 PM, Thomas Meire<blackskad gmail com> wrote:
Hi all, I tried to store a double in a Gee.Map for some algorithms I'm writing, but the program failed to compile (with valac errors). After reading a bit in the tutorial[1] and the reference draft[2], I decided to try the example in the reference manual[3]. However, the program failed to compile with the same error I had in my algorithms: "error: `double' is not a supported generic type argument, use `?' to box value types" So I changed that line a bit to look like: var t = new Two < int, double? > (); With that line, it compiles (with some warnings), but the output is not correct. It outputs some 'random' value instead of 5. So what can i do to make the program compile and make it do what it's supposed to do?
