exception using QL_Fail/QL_Require

Dear all,

i have started a new project which depends on Quantlib and i have successfully built it (in fact i currently only use QL error macros, i.e QL_FAIL)

However whenever the compiler goes to QL_FAIL line, it gives exception message and stopped working:

First-chance exception at 0x7503b727 in project.exe: Microsoft C++ exception: QuantLib::Error at memory location 0x0041f424..

Unhandled exception at 0x771f15ee in project.exe: Microsoft C++ exception: QuantLib::Error at memory location 0x0041f424.

my code is very simple and i use QL_FAIL like:

if(!file.is_open())

{

QL_FAIL(" the file does not exist");

}

I tried QL_Require it gives same error.

I see ERROR macro works fine in Quantlib but cant figure out what goes wrong in my project. Could someone pls give kindly some advise?

Thanks in advance,

Hans

Re: exception using QL_Fail/QL_Require

Hi Hans,

QL_FAIL and QL_REQUIRE and the like throw an QuantLib::Error which extends std::exception. So what you see is perfectly expected, it is just the result from an uncaught exception. To see the error message you have to catch the exception and output it’s what()-result to std::clog or the like.

Kind Regards

Peter

答复: exception using QL_Fail/QL_Require

Hi Peter,

Thanks for your clarification. I understand how it works now.

In example folder i saw following code, which shows me how to use QL_FAIL properly.

try{..

} catch (QuantLib::Error e) {

std::cout << "terminated with a ql exception: " << e.what()

<< std::endl;

return 1;

} catch (std::exception e) {

std::cout << "terminated with a general exception: " << e.what()
