[Quantlib-dev] pure virtual function call in observable update

[Fischbein, A. C. (NYK) <Ala...@C1...>]

Hi,

This message is intended as a follow-up to:
 http://old.nabble.com/Issues-with-C--Swig-Bindings%2C-NUnit-and-Settings.instance%28%29.setEvaluationDate%28%29-to30549787.html#a30663710
I am experiencing the same issue as the one reported: random occurrences of "pure virtual function call" in the 'update' method in 'notifyObservers'. I tried the solution suggested by Henner Heck - using his new observable.hpp that uses "enable_shared_from_raw.hpp".
I got that file, and the new shared_ptr.hpp from the trunk referenced by Henner. I also made the changes in his post. Boost and QuantLib compile OK, but when I build my own project (managed C++), I get an array of warnings (though it does build.)
Many like this:
2>c:\program files (x86)\boost\boost_1_44\boost\thread\win32\thread_primitives.hpp(314): warning C4793: 'boost::detail::win32::interlocked_bit_test_and_set' : function compiled as native :
2>      Found an intrinsic not supported in managed code

plus others related to features not supported by clr/managed code.

Plus one these for each source file:
I_EuropeanOption.obj : warning LNK4248: unresolved typeref token (01000024) for 'boost.detail.win32._SECURITY_ATTRIBUTES'; image may not run


though I managed to get rid of these with this: http://exold.com/article/using-boost-with-managed-c

As I mentioned, it does build. The real problem is that when I run my project, I immediately get:
BadImageFormatException: Could not load file or assembly 'Interface.dll' or one of its dependencies.  is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)

Interface.dll is my managed C++ project.

My setup:

Windows XP 64-bit Professional (though all code is compiled for 32-bit / x86)
Visual Studio 2010
Boost 1.44
QuantLib 1.0.1
A 'core' project that is native C++ that uses quantlib; compiled to a static library.
A 'Interface' project that is managed C++, built into a DLL. (so the code is not linked until this project is built.)
An 'add-in' project that is C#/.NET 4.0. The above error is thrown when this project tries to create an instance of a class in Interface.dll

Everything runs fine (except for the occasional 'pure virtual function call') with the original setup - not even any build warnings.

Does anyone have any suggestions on how to proceed? Please let me know if you need more details about my setup.
Thanks.

         - Alan
