I am trying to load a dynamic library using dlopen function. This library contains a static object, which throws an exception in its constructor. I have a ‘try-catch(…)’ block around the dlopen call, but it doesn’t catch the exception, and I just see ‘Abort’ printed.
How am I able to catch this exception?
Short Answer: You Can’t
Thinking about it again.
The original statements holds, but you must also remember that dlopen() is a C library function. C does not support exceptions. Thus throwing an exception that crosses from C++ code to C ( Your global object back upto dlopen() ) code will also cause application termination.
See here:Why destructor is not called on exception?
These are the situations under which throwing an exception will terminate the application. Your specific situation is covered by:
An exception escapes the constructor/destructor of a non local static (ie global)
