Silly linker question

Grześ Andruszkiewicz
Hi,

I have some blackout currently... I just added a test project to my
solution, but it fails to link:
1>------ Rebuild All started: Project: CatBonds, Configuration:
Release Win32 ------
1>  CatBond.cpp
1>  catcoupon.cpp
1>  CatRisk.cpp
1>  Main.cpp
1>  riskynotional.cpp
1>  Generating code
1>  Finished generating code
1>  CatBonds.vcxproj ->
C:\Users\ga\Documents\dev\imperial\Oasis\Release\CatBonds.exe
2>------ Rebuild All started: Project: Test, Configuration: Release Win32 ------
2>  catrisktests.cpp
2>  exampletests.cpp
2>  testrunner.cpp
2>catrisktests.obj : error LNK2001: unresolved external symbol
"private: static long __cdecl QuantLib::Date::yearOffset(int)"
(?yearOffset@Date@QuantLib@@CAJH@Z)
2>catrisktests.obj : error LNK2001: unresolved external symbol
"private: static int __cdecl QuantLib::Date::monthOffset(enum
QuantLib::Month,bool)" (?monthOffset@Date@QuantLib@@CAHW4Month@2@_N@Z)
2>catrisktests.obj : error LNK2001: unresolved external symbol
"public: static bool __cdecl QuantLib::Date::isLeap(int)"
(?isLeap@Date@QuantLib@@SA_NH@Z)
2>catrisktests.obj : error LNK2001: unresolved external symbol
"public: int __thiscall QuantLib::Date::year(void)const "
(?year@Date@QuantLib@@QBEHXZ)
2>catrisktests.obj : error LNK2001: unresolved external symbol
"public: enum QuantLib::Month __thiscall
QuantLib::Date::month(void)const "
(?month@Date@QuantLib@@QBE?AW4Month@2@XZ)
2>catrisktests.obj : error LNK2001: unresolved external symbol
"public: __thiscall QuantLib::Date::Date(void)"
(??0Date@QuantLib@@QAE@XZ)
2>catrisktests.obj : error LNK2001: unresolved external symbol
"public: __thiscall QuantLib::Date::Date(int,enum
QuantLib::Month,int)" (??0Date@QuantLib@@QAE@HW4Month@1@H@Z)
2>C:\Users\ga\Documents\dev\imperial\Oasis\Release\Test.exe : fatal
error LNK1120: 7 unresolved externals
========== Rebuild All: 1 succeeded, 1 failed, 0 skipped ==========

It seems to have the same library paths as the first project that
works... What am I missing?


Cheers,
Grzegorz

Re: Silly linker question

Luigi Ballabio
Besides the library path, did you add the library itself? (It is done
implicitly if you add its project as a dependency; otherwise, you have
to add it in the linker options.)

Re: Silly linker question

Grześ Andruszkiewicz
Hi,

Thanks for your replies, I found it finally! Indeed as Peter suggested
the autolinker thing was missing, so adding:
#include <ql/auto_link.hpp>

to the main file fixed the issue. In the project that worked Lorenzo
added the whole #include <ql/quantlib.hpp>, so I didn't even realize
that the autolinker was needed and that it was hidden inside it!


Cheers,
Grzegorz
