Linker Error using Dev-C++ when including quantlib.hpp for test reasons

[thomas ehlenz]

Hi,

 

I am using Dev-C++ and got boost 1.47.0, built it, got QuantLib 1.0.1, built it using the Dev-C++ project file "QuantLib.dev" --> library "libQuantLib-mgw.a" was created.

 

To test QuantLib I just included quantlib.hpp (#include <ql/quantlib.hpp>) in a standard 6 line code template and got tons of linker Errors (... undefined reference to 'Quantlib::...). Without the #include <ql/quantlib.hpp>, there's no problem.

 

I set up all include and library paths for boost as well as for quantlib in Dev-C++ (as you can see in the compiler log further down), so that should be fine.

 

What's the problem, why can't the linker find all the Quantlib methods, attributes and so on?

 

Greetings,

Thomas

 

The first lines of the compiler log reads:

Hello Thomas,
    you're adding the library path, but not the library itself. You
have to tell Dev-C++ to add libQuantLib-mgw.a to your project.
