It's looking for the constructor:

    std.stream.File.this(char[], enum std.stream.FileMode)

_D: prefix for all D functions
3std: std is 3 characters long
6stream: stream
4File: File
5_ctor: the 'this' constructor
F: function, next comes parameter types
A: array of
a: chars
E: enum
3std6stream8FileMode: std.stream.FileMode
Z: end of function parameter types, next comes return type
C: class
3std6stream4File: std.stream.File

__init_: initializer for class
30TypeInfo_PC5world11SectorCache: TypeInfo class generated for type:
   P: pointer
   C: class
   5world11SectorCache: world.SectorCache

P.S. These are not templates, so this isn't the template issue discussed earlier.

Where is the initializer inserted?
I don't see how it could be missing since I can do this:

class SectorCache {}
class CacheList : CList!(SectorCache) {}

and it still gives the same error.

If I strip these classes down, however the error goes away.  I dropped it to the 6 most basic files and I got no error at all.  The CList class I posted is fairly simple; it doesnt seem to be missing anything.

I just dropped my CList implementation for Ben's CircularList and I still get:

>>> E:\proj\d\game\obj\world.obj(world)
>>>  Error 42: Symbol Undefined __init_29TypeInfo_C5world11SectorCache

this is with :

class SectorCache {}

I suggest doing a grep for __init_29TypeInfo_C5world11SectorCache across all your .obj and .lib files.

I reverted back to my original list class and did a grep for the missing symbol:
"__init_50TypeInfo_C5clist26CList_C5world11SectorCache5CList"

which was found in world.obj.

I also double checked that this file is included in the link command.

You can use obj2asm.exe to see if it is a definition or an extern reference.

But anyhow, there's not much anyone can do without being able to reproduce the problem you're seeing.

Its an extern reference when i disassemble.

extrn   __init_29TypeInfo_C5world11SectorCache

I still do not understand the _why_ of this problem, Walter.
Is the TypeInfo a pseudo class and just isnt instantiated?
If I have violated some rules within D then its my fault, but all I see is plain, vanilla D code which fails under these circumstances.

I would much like to find this problem on my own, I simply do not understand what is happening nor how to proceed.

I can send anyone the project (a 3d game editor, or the beginnings of one ) who wishes to try( although it isnt what I would call 'ready for the public').

PS. The other reference is also an extrn

extrn	__init_50TypeInfo_C5clist26CList_C5world11SectorCache5CList

I wouldn't mind giving it a try troubleshooting.  brk_6502@yahoo.com

I don't know either, but these problems become understandable when everything else gets stripped away. They nearly always boil down to 10 lines of code or less. Then they become understandable, and fixable.
