Are you importing certain modules without compiling those same modules 
and linking them with your code?

I am using my DManager project tool so I am certain all files are 
compiled and on the link line. (posted below)

dmd E:\proj\d\game\obj\actor.obj E:\proj\d\game\obj\bmp.obj 
E:\proj\d\game\obj\client.obj E:\proj\d\game\obj\editor.obj

Ive been lazy about learning Dereks Build, so I haven't attempted that 
yet :( but the command line version should work.  Amazingly this happens 
when I attempt to use my CList (circular list) template class( posted ) 
with the SectorCache class.  A constructor for CList uses TypeInfo 
arguments, but I don't see how it could result in missing symbols.

This even more proof of the similarity to the problem I was having with 
optlink.  My linux version worked the same way despite the failure of 
the windows version.

I'm pretty sure this is very similar to the "template-in-library" 
problem that I had.  It's been diagnosed and it is windows specific. 
It's due to the OMF format short-comings.

There is a workaround.

Look at "Hair-pulling, D, and Optlink" on the d.newsgroup.  Walter 
explains it.

CList in and of itself isnt the problem. Its using CList with another 
class(SectorCache).

Like I said I commented out all of SectorCache class members and the 
error persists.  Of course putting CList and SectorCache in a simple 
file alone does not generate the error.

I can send you the project if you want to peruse it but the bottom line 
is the error message makes no sense whatsoever.  I could probably fix 
this on my own if I had some clue what was happening.

Please try to reduce the test case before sending it.
I'd be surprised if this requires more than 3 source files.

Try deleting all the obj files and recompiling cleanly. Also it seems odd 
that std.stream symbols can't be found so I'd check your phobos version or 
path to phobos or something. But first I'd to a clean rebuild to see if the 
problem is crufty obj files.

Can you wipe up a simple file that uses std.stream.File and
std.stream.FileMode ?

Note: Those messages aren't produced by dmd but by the linker.

Actually the file stream issue was due to a mis-copy of the link command 
into a command window.

Only the following two errors are the issue:

E:\proj\d\game\obj\world.obj(world)
  Error 42: Symbol Undefined __init_29TypeInfo_C5world11SectorCache
E:\proj\d\game\obj\world.obj(world)
  Error 42: Symbol Undefined 
__init_50TypeInfo_C5clist26CList_C5world11SectorCache5CList
--- errorlevel 2

I went ahead and commented out all the members and methods of 
SectorCache, did a full build, and still the error remains.

The only line I can remove from my project to eliminate the error is

alias CList!(SectorCache) CacheList;

Heh... This looks like a similar error to the one I just finished 
experiencing.  I noted it in the digitalmars.d newsgroup.

See "Hair-pulling, D, and Optlink"

Walter explains the problem of having a template-only-containing object 
file inserted into a library.  You don't appear to be using a lib file 
here... but perhaps the problem is related?

 seems odd that std.stream symbols can't be found so I'd check your 
 phobos version or path to phobos or something. But first I'd to a 
 clean rebuild to see if the problem is crufty obj files.




 Dmanager has a full build option, so I had tried that.  I just 
 deleted them by hand and retried with the same results.





 Can you wipe up a simple file that uses std.stream.File and
 std.stream.FileMode ?

 Note: Those messages aren't produced by dmd but by the linker.

 Actually the file stream issue was due to a mis-copy of the link 
 command into a command window.

 Only the following two errors are the issue:

 E:\proj\d\game\obj\world.obj(world)
  Error 42: Symbol Undefined __init_29TypeInfo_C5world11SectorCache
 E:\proj\d\game\obj\world.obj(world)
  Error 42: Symbol Undefined 
 __init_50TypeInfo_C5clist26CList_C5world11SectorCache5CList
 --- errorlevel 2

 I went ahead and commented out all the members and methods of 
 SectorCache, did a full build, and still the error remains.

 The only line I can remove from my project to eliminate the error is

 alias CList!(SectorCache) CacheList;

 -DavidM


 
 
 Heh... This looks like a similar error to the one I just finished 
 experiencing.  I noted it in the digitalmars.d newsgroup.
 
 See "Hair-pulling, D, and Optlink"
 
 Walter explains the problem of having a template-only-containing object 
 file inserted into a library.  You don't appear to be using a lib file 
 here... but perhaps the problem is related?
 
 -JJR



I just read Walter's reply in that thread, and I am not sure I fully 
understand.

If I use:

alias  CList!(SectorCache)	CacheList;

Then explicitly link in 'clist.obj' it should be linked in with the exe 
no matter what.  Why would the _type_ above be removed? There are no 
duplicates of it anywhere.  Even if I replace the line with

class CacheList : CList!(SectorCache) {}

it still does not link!

Walter, little gotchas like this can really doom D.  Whether or not its 
fast, simple, garbage collected, etc doesn't matter if legal constructs 
within the language will not compile or link.  I am not trying to 
trivialize the technical issue, but I am emphasizing the usability issue 
here.

Well... true. It may not be the same issue then.  This problem should 
not surface with a single object file.  I wasn't sure how you were 
linking things in or where that particular object was.  It's only likely 
to happen if this object file resides in a library.

I'm afraid I don't understand what's going on here.

Just out of curiosity, maybe you can try Walter's trick... it can't hurt 
trying.

1) add "int foo;" to the bottom of the clist.d file.
2) add "int* pfoo = &clist.foo" to one of the files that uses the CList 
template (any one that imports it).

See if you can link again.

 Walter, I _IMPLORE_ you to clean up the error messages.

 In the meantime can someone please help to decode what the following 
 gibberish means?  I don't have an init() method for the class SectorCache 
 (nor its TypeInfo???) so I am pretty stumped here.


Note the __init_ isn't for an init() method but is the initial values of the 
class instance. Right after allocating the instance the __init values are 
copied to the allocated space and then the ctor is called. Do you have any 
variables of type CacheList declared in the same module where the CacheList 
alias is declared?

Yes.  The type CList is still not making its way into the object file.

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.

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

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').

Hehe, a new twist to my dilemma.

Currently my project pulls files from about 5 different directories.

When I put everything into one directory(to send to John)...it links fine.

Sigh.

In each case all the obj files are dumped into a single directory, so I 
don't see how where they are relative to each other could affect the 
link process.
