"Internal error" when compiling

Monkey Forums/Monkey Bug Reports/"Internal error" when compiling

Hello,

This is a report related to the problem discussed on the following thread: http://www.monkeycoder.co.nz/Community/posts.php?topic=4931

The problem specified by trans does not point to any specific error, so I'm a bit stumped, but it occurs when compiling, and trans is produces no code. It may or may not have something to do with how Generics are used in the code.

Steps to reproduce:

1. Clone or download the source located here: https://github.com/nobuyukinyuu/monkey-timsort
2. Attempt to compile
3. ??????

Can you please post a runnable example here?

The repo is a runnable example.

yes, the repo should have all the files you need. The entry point is located in TimSortTest.monkey. Let me know if there's any problems with any of this.

direct link to repo clone:
https://github.com/nobuyukinyuu/monkey-timsort/archive/master.zip

Here's an alternate version of TimSortTest.monkey that only uses the function call (same error occurs):

Import mojo
Import timsort

Function Main:Int()
	New Test()
End Function

Class Test Extends App
	Field arr:Int[]
	Const ARR_LEN:Int = 64
	
	Method OnCreate:Int()
		SetUpdateRate 60
		
		'Populate the array.
		arr = arr.Resize(ARR_LEN)
		For Local i:Int = 0 Until ARR_LEN
			arr[i] = Rnd($FFFFF)
		Next

	End Method
	
	Method OnUpdate:Int()
		If KeyHit(KEY_SPACE)
			Local ms:Int = Millisecs()

			TimSort<Int>.Sort(arr, New IntComparator)
			
			Local now:Int = Millisecs()
			now -= ms
			Print("Sort took " + now + " millisecs")
		End If
	End Method
	
	Method OnRender:Int()
		Cls
		For Local i:Int = 0 Until ARR_LEN
			DrawText(i + ": " + arr[i], 8, i * 16)
		Next
	End Method
End Class

Ok, can reproduce, but there's a lot of code there - any chance you can reduce it down a bit?

Think I've found it - there's an issue with Select statements in generic code.

Will fix, but you can get it around it for now by using If/Else If/etc instead of Select in Method TimSort.binarySort().

Thanks a bunch. That sounds like an obscure one! Guess now it's time for me to get back and see if I can get the rest of the code working -- there were a number of small things that I seem to have missed...
