mfc, GetDocument( ) link error

1. CTestDoc* GetDocument() errors in view class

I am getting these errors in my view header:

error C2143: syntax error : missing ';' before '*'
error C2501: CTestDoc: missing storage-class or type specifiers
error C2501: 'GetDocument' : missing storage-class or type specifiers

for this statement:

CTestDoc* GetDocument();

Currently, I am using

class CTestDoc;

earlier in the file to satisfy the need.

Can I get some help on this?  Much appreciated!

2. A Linking Error in VC++.net when linking to a WinCE.net dll

3. Unresolved link error, link incremental DID NOT fix!!!!

I posted a message about including a GSM library in VC++ 6.0 on a new project and I thought I had fixed it by selecting "link incremental". Well, I found out that DID NOT FIX IT. I had commecnted out the offending line:
gsmh = gsm_create();
for other testing, and forgot to uncomment it when I made the linker change ( I blame a 13 hour day for that). However, now I am right back where I started Here is the original post. Any help greatly appreaciated.

I wrote an application in VC++ 5.0 that used an external library for GSM 6.10 encode/decode and it worked fine. I started using VC++ 6.0, built the app under it and it worked fine. Now I find myself creating a new app using GSM 6.10 in VC++ 6.0, but I have run into a problem.

I add the file gsm.lib by 
Project->Setting->link->Object/library modules for all configurations. winnmm is also declared there and all calls to it's functions work fine.

But, when I attempt to build and call gsm_create() I get the following error:
 error LNK2001: unresolved external symbol "struct gsm_state * __cdecl gsm_create(void)" (?gsm_create@@YAPAUgsm_state@@XZ)

It must be finding the gsm.lib file because if I change it's name to something like gsm.lib.t, the linker complains of no such file gsm.lib.

Why am I getting the unresolved error?

4. link error lnk2003 while linking IA64 application

5. Project links just fine in VC6 but link errors in 7.1

Posted this in the MFC group.  I did not get any response over there and 
I realized this is probably a more appropiate group so I am now posting 
it here,

I wrote a DLL using VC++ 7  (unmanaged) .  I have a small application 
that uses this DLL.  The application links just fine using VC6.  But if 
I try linking the same application using VC7, I get the following link 
error:

TestLink error LNK2019: unresolved external symbol 
"__declspec(dllimport) public: unsigned int __thiscall 
GarXface4::GxList<class GarXface4::ComPortName>::GetCount(void)" 
(__imp_?GetCount@?$GxList@VComPortName@GarXface4@@@GarXface4@@QAEIXZ) 
referenced in function "protected: virtual int __thiscall 
CTestLinkDlg::OnInitDialog(void)" (?OnInitDialog@CTestLinkDlg@@MAEHXZ)


There are other class and methods within the lib / dll that give no link 
errors.  I am exporting them and importing them all the same way.


Strange thing is that some methods of GarXface4::GxList<class 
GarXface4::ComPortName> link just fine.

for example this links:

GarXface4::GxList<class GarXface4::ComPortName> comportlst;
comportlst.Clear();


but I get a link error with:


GarXface4::GxList<class GarXface4::ComPortName> comportlst;
unsigned c = comportlst.GetCount();


Any idea what I should look for?  Why would it link under VC6 but not VC7?


BTW

GarXface4::ComPortName cpn;
cpn.GetDeviceName();


links just fine so I am pretty sure it is not GarXface4::ComPortName 
causing the problem.
