puzzel: cannot open file 'QuantLib-vc90-mt-sgd-0_9_7.li
Locked

Hi All, I am very new to quantlib. I use vs team system 2008, quantlib 0.97, boost 1.39. Here is the problem puzzled me; 1. I built quantlib, 'QuantLib-vc90-mt-sgd-0_9_7.lib' is in the lib directory. 2. I build static library libCrr.lib with essentially two files: clsLGM.h: #ifndef _CLS_LGM_H #define _CLS_LGM_H #ifdef __cplusplus extern "C" #endif int testQL(); #endif clsLGM.cpp: #include "stdafx.h" #include <ql/quantlib.hpp> #include <boost/timer.hpp> #include <iostream> #include <iomanip> //#include "clsLGM.h" using namespace QuantLib; #ifdef __cplusplus extern "C" #endif int testQL() { boost::timer timer; std::cout << std::endl; Date todaysDate(15, February, 2002); Calendar calendar = TARGET(); Date settlementDate(19, February, 2002); Date startDate = calendar.advance(settlementDate,1,Years, ModifiedFollowing); return startDate.year(); //return 1; } 3. 'testQL' function is called from xll addin project (xllCrr) written in C, ( I have to compiled it as C, excel 2003 don't recognise it's a addin if compiled as C++). Now is the puzzle: The xllCrr's link failed: cannot open file 'QuantLib-vc90-mt-sgd-0_9_7.lib' I don't see why xllCrr need to link with QuantLib-vc90-mt-sgd-0_9_7.lib. Isn't everything quantlib is in libCrr.lib I built? How does xllCrr know there is a lib called QuantLib-vc90-mt-sgd-0_9_7.lib. I checked environment variable, but nowhere link to QuantLib-vc90-mt-sgd-0_9_7.lib. I set 'Ignore Specific Library' to QuantLib-vc90-mt-sgd-0_9_7.lib in the project setting, I then will get some other errors include quantlib related: libCrr.lib(clsLGM.obj) : error LNK2019: unresolved external symbol "public: int __thiscall QuantLib::Date::year(void)const " (?year@Date@QuantLib@@QBEHXZ) referenced in function _testQL May be the project setting for the static library libCrr.lib setting is wrong?

My intention is to write a C library wrapping Quantlib time/date function. The library will be statically linked, means the lib will be independent of Quantlib when built. In other word, when other program can use the lib independent of Quantlib. Is it possible? Many thanks, Yan

This means that if you don't want to link QuantLib, you'll have to include the time/date QuantLib sources in your library and compile them together with your wrappers.

Hi Luigi and Nando, Thanks for the help. I built my c wrapper. The other project xCrr can't find 'QuantLib-vc71-mt-sgd-0_9_7.lib', I did anything possible to set the lib dependence. I don't mind xCrr knows QuantLib-vc71-mt-sgd-0_9_7.lib, as long as it links. Why I need to do the wrapper? My excel addin code doesn't work properly if I compiled as C++. That's why I need to write a C wrapper. I think all the problems are caused of vs 2003, my installation even refused to install SP1.Now I have updated to vs 2008. I will need to update to excel 2007 to use sdk 2007 shortly. So I have moved on, but the question is still remaining. Under vs 2008, my c wrapper becomes a small C++ price library. In my current project, I start to use quantlib's swaption vol cube, I found it is good. I will only use vol cube, date function of quantlib, may try PDE if I got time, as I already got my PDE code. That means my price libary is not a standalone library. Is QuantLib-vc90-mt-sgd-0_9_7.lib the only binary it depends on? (From auto_link.hpp, it appears to be). Is my addin XLL a standalone application? If the XLL is standalone dll, doesn't that mean I can make dll standalone, but not a static library? Sorry I never heard of autolink before. I can't think it's C++ standard. What's the advantage? How do I enable it? How do I disable it? Also I can't see any direct test cases of PDE in testsuite? Is there any indirect test cases on PDE in the suite? A more general question would be: when a developer submits/checks in new lib, does she/he have to submit test cases? Wouldn't be that the test cases being added to the official suite? Cheers, Yan

OK, I realised static library is just object files, Compiler/(Linker?) doesn't add the binary from the dependant library to the static library. However with autolink, Compiler/(Linker?) put the dependant library name string (QuantLib-vc90-mt-sgd-0_9_7.lib defined in autolink.hpp) into the static library. So the dll or exe using the static library 'know' which library which the static library depends on to link. Sorry for the confusion, Yan
