[Coin-discuss] Error when compiling with Visual Studio using the CoinBinary project

[Andreas Lundell]

Hi all,

The last couple of days I've been trying to compile a simple test 
project in Visual Studio using the binary libraries from the 
CoinBinary/CoinAll project (COIN-OR-1.7.3) dated 26-27 November 2013.

If I use the following code:

     #include "OSInstance.h"
     ...
     int _tmain(int argc, _TCHAR* argv[])
     {
         OSInstance * instance;
         instance = new OSInstance();
         return 0;
     }

The compiler gives back something like "error LNK2019: unresolved 
external symbol "public: __thiscall OSInstance::OSInstance(void)" 
(??0OSInstance@@QAE at XZ) referenced in function _wmain".

The same is true if I change the OSInstance to some other class. I've 
included the libraries in the lib-folder of the COIN-OR-1.7.3 package 
and the header files in the include-folder are also used by the 
compiler.  I've also tried the different versions available of the 
package (msvc9-11) in combination with the corresponding version of 
Visual Studio (2008, 2010 and 2012).

The binary files bundled with the package works well.

Any ideas what's wrong and how to fix it?

Regards,

Andreas Lundell
