fatal error LNK1104: cannot open file 'QuantLib-vc80-mt-0_9_7.lib'

[Norman Fung-2]

hello

I created a simple WIN32 console application. I keep getting this error as soon as I add this line to main.cpp:

#include <ql/quantlib.hpp>

The linker error is:

Error    29    fatal error LNK1104: cannot open file 'QuantLib-vc80-mt-0_9_7.lib'    SimpleWIN32Console   

I have already included ...
STEP 1: Tools\Options\VC++ Directories\Library Files\
                I:\dev\QuantLib\QuantLib-0.9.7\lib

STEP 2: Tools\Options\VC++ Directories\IncludeFiles\
                I:\dev\QuantLib\QuantLib-0.9.7

I then checked lib folder, there exists the following two files (but not the one in linker error message):
(file-a) QuantLib-vc80-mt-s-0_9_7.lib
(file-b) QuantLib-vc80-mt-sgd-0_9_7.lib

What's with "-s-" and "-sgd-" in lib file name? And where in "QuantLib" can I find reference to "QuantLib-vc80-mt-0_9_7.lib"? I cheated and manage to successfully compile and get rid of linker problem by renaming "file-a" to "QuantLib-vc80-mt-0_9_7.lib", thought there should be a more elegant way to do this!

Thanks!

Norman

You compiled the static-runtime version of QuantLib. In your application
project, instead, the run-time settings tell the linker to look for the
shared-runtime version. You'll have to sync the two; either recompile
QuantLib in Release mode (no static runtime), or change your project
settings (in the properties, they're under Configuration Properties /
C/C++ / Code Generation; choose "Multi-threaded DLL".)

P.S. The other issue you have with multiply-defined symbols is probably
due to your using a renamed library, thus pulling in two versions
(static and shared) of the runtime.

Just managed to compile+run the examples as well!

Thanks guys
