Dear Luigi and QuantLib Users,

Thank you very much for the reply. I am very appreciate your help.

 I was not aware of it. Thank you for pointing it out. I just recompiled library in release mode ( QuantLib-vc90-mt-0_9_7.lib). It also automatically runs test suite with success.

This is very helpful suggestion.  There is small issue with auto_link.hpp, though.

Line 63: #define QL_LIB_NAME "QuantLib-" QL_LIB_TOOLSET QL_LIB_THREAD_OPT QL_LIB_RT_OPT "-"
QL_LIB_VERSION ".lib"

QL_LIB_VERSION  macro is not defined in auto_link.hpp but in qldefines.hpp. So, I have included also qldefines.hpp  header.

I could compile main.cpp in debug/release mode including
    #include <ql/qldefines.hpp>
    #include <ql/auto_link.hpp>
 with following configuration properties:

Debug Mode:

    1.   Configuration Properties->General->Additional Include Directories   
          C:\....\QuantLib-0.9.7
     2.  Configuration Properties->Preprosessor->Preprocessor Definitions
          WIN32;_DEBUG;_CONSOLE;_SCL_SECURE_NO_DEPRECATE;_CRT_SECURE_NO_DEPRECATE;
     3.  Configuration Properties->Code Generation->Runtime Library
          Multi-threaded Debug (/MTd)
     4.  Configuration Properties->Linker->Additional Library Directories
          C:\....\QuantLib-0.9.7\lib

Release Mode:

    1.   Configuration Properties->General->Additional Include Directories   
          C:\....\QuantLib-0.9.7
     2.  Configuration Properties->Preprosessor->Preprocessor Definitions
          WIN32;_DEBUG;_CONSOLE;_SCL_SECURE_NO_DEPRECATE;_CRT_SECURE_NO_DEPRECATE;
     3.  Configuration Properties->Code Generation->Runtime Library
          Multi-threaded DLL (/MD)
     4.  Configuration Properties->Linker->Additional Library Directories
          C:\....\QuantLib-0.9.7\lib


Thank you,
Boris.

Just checking: you're aware that QuantLib-vc90-mt-sgd-0_9_7.lib is
compiled in debug mode and is much slower than the release version,
right?

This is not necessary. Instead of specifying the library directly, it's
better to add

#include <ql/auto_link.hpp>

to one of your source files. The above will try to pull in the correct
version of the library for your project settings, so that you won't have
linker errors like the ones you reported.  The downside is that, if you
want to link a specific library you compiled (such as
QuantLib-vc90-mt-sgd-0_9_7.lib) you'll have to adjust your project
settings accordingly. In your case, I think you'll to choose debug mode
and to set Configuration Properties -> C/C++ -> Code Generation as
"Multi-threaded".
