Linker Error

Hello All,

I have a Visual C++ 2003 dll solution in a directory called "Antenna
Test Range Control", and when I comile it, I get the error LNK1104:
cannot open file "antenna.ob j". When I remove teh spaces in my solution
directory, I get the following errors:

MastController. exp : error LNK2001: unresolved external symbol _Calibrate@8
MastController. exp : error LNK2001: unresolved external symbol _Initialize@8
MastController. exp : error LNK2001: unresolved external symbol _IsAlive@4
MastController. exp : error LNK2001: unresolved external symbol _IsMoving@4
MastController. exp : error LNK2001: unresolved external symbol _MoveAz@12
MastController. exp : error LNK2001: unresolved external symbol _MoveEl@12
MastController. exp : error LNK2001: unresolved external symbol
_NotifyOnComple te@8
MastController. exp : error LNK2001: unresolved external symbol _Stop@0
I know this is a linker problem, but I don't know what to do.

Any ideas? Thanks.

Don't remove the spaces - if you do that the path becomes invalid since
there's no such directory.

Put quotes around the full path : e.g. "c:\abc and zyx\lots of spaces in
this folder\a b c d....."

Ooops - I'm sorry - I should've specified that I renamed the containing
directory to a name with no spaces - I didn't change any of the code in
the project. However, the environment macros *did* change to reflect
the change in $(SolutionPath) and such.

Okay, I went into the linker options and put double quotes around my
"Additional Dependancies," which brings about the same effects as
putting the project in a path with no spaces, except that I now have a
new problem with "__DllMainCRTSt artup@12"...

Here are the errors that I get:

LINK : error LNK2001: unresolved external symbol __DllMainCRTSta rtup@12
MastController. exp : error LNK2001: unresolved external symbol _Calibrate@8
MastController. exp : error LNK2001: unresolved external symbol _Initialize@8

MastController. exp : error LNK2001: unresolved external symbol
_NotifyOnComple te@8
MastController. exp : error LNK2001: unresolved external symbol _Stop@0
Debug/MastController. dll : fatal error LNK1120: 9 unresolved externals

What do I do to resolve them?

Add /verbose to your linker command line options and study the output
produced. Are the files where you expect those symbols to be defined
actually being included in the link?

Use dumpbin /symbols on the .obj files that should define those symbols - do
they in fact define them?

For some reson my code is generating a LNK1215 error, which 'suggests' I re-install VS C++. So I did. which did NOT solve the problem.

After that I have to bring back in an old version of the code to make it work again (not fun)... This seems like a REAL LINKER error, not...

After porting a project from VC6 to VC.NET 2003 I have a very strange problem generating link error 1104 for import libraries. I just ported the project and made some small adaptions so it fits the new IDE. The project itself links against some import libraries belonging to dll's I wrote (these dll's have been ported too, of course). To keep things simple I only use one import library here.
