Hello, 
I'm trying to link Mathematica to an external c++ lib using the following 
script from command prompt:

SET CL=/nologo /I "C:\QuantLib\QuantLib-1.0.1" /I "C:\Boost\boost_1_43" /c 
/DWIN32 /D_WINDOWS /W3 /O2 /DNDEBUG

SET LINK=/NOLOGO /SUBSYSTEM:windows /INCREMENTAL:no /PDB:NONE /LIBPATH:"C:
\QuantLib\QuantLib-1.0.1\lib" QuantLib-vc80-mt-s.lib kernel32.lib advapi32.lib 
user32.lib gdi32.lib winspool.lib comdlg32.lib shell32.lib ole32.lib oleaut32.
lib uuid.lib odbc32.lib odbccp32.lib opengl32.lib glu32.lib glaux.lib

MPREP QL.tm -o QLtm.cpp

CL QL.cpp QLtm.cpp

LINK QL.obj QLtm.obj ml32i3m.lib /OUT:QL.exe

It seems everithing goes well till the last command where I get the following 
error:

C:\QLMma\QL\QLibMma>LINK QL.obj QLtm.obj ml32i3m.lib /OUT:QL.exe
QLtm.obj : error LNK2019: unresolved external symbol "void __cdecl

QL.exe : fatal error LNK1120: 2 unresolved externals

Any suggestion is appreciated...
