Hello, thanks for feedback.

We followed the procedure described in the two links.

We're using Visual Studio 2012 to compile both the QuantLib1.4 and the QuantLib-SWIG.

Step followed

1) enabled for the QuantLib Solution the BOOST_SP_ENABLE_DEBUG_HOOKS preprocessor directive

2) Replaced the files observable.hpp and observable.cpp (got from here ) and rebuild the entire QuantLib library 

3) enabled for the QuantLib-swig Solution the BOOST_SP_ENABLE_DEBUG_HOOKS preprocessor directive (maybe this is wrong but we failed also without the directive)

4) restart build for the QuantLib-SWIG solution.

we had following errors (here just a row of the error list)

QuantLib::Observer::unregisterWith(class boost::shared_ptr<class QuantLib::Observable> const &)" (?unregisterWith@Observer@QuantLib@@QEAA_KAEBV?$shared_ptr@VObservable@QuantLib@@@boost@@@Z) unresolved external

-- It seems that the new quantlib did not considered the preprocessor directive

5) we have done some different attempts changing the directive inside the QuantLib-swig Solution without success

Where do you think we had done some error ?

Thanks in advance, Cheers.

Hello,

    sorry, there's no setting to enable logging. I'll make a guess though: might your crashes in Java be related to the problem described by Klaus at <http://hpcquantlib.wordpress.com/2012/02/27/quantlib-swig-and-a-thread-safe-observer-pattern-in-c/> and <http://hpcquantlib.wordpress.com/2013/07/26/multi-threading-and-quantlib/>?

Hello, and thanks in advance for feedback.

Is there a setting, can we use, to increment LOG verbosity of the quantlib and quantlib-swig libraries ?

We're using the C++/Quantlib64bit + Quatlib-swig-Java 64 library and we have some rare crash but we're not able to collect any information on it.

All the best, Roberto
