RE: Can't catch any throw on gcc 3.0.4

[Tan-Long Phan]

Hi Lyle

Yes, I'm linking my stuff with g++ and the exceptions are thrown across
library boundaries. My main application was linked with different dynamic
libraries and static libraries, the try and catch are done in the static
library and the exceptions are thrown from the dynamic library.

Thanks & Regards

Long

Are you linking your application using g++ or gcc?  You should be using
g++.  Also, are you throwing the exception across library boundaries, or
is it all in the same executable or library?

Thanks,
Lyle

Hi 

I'm writing an application on Linux 7.3 using gcc 3.0.4 and having a
little
problem with the exception handling. It works fine with MSVC. The stack
was:

RE: Can't catch any throw on gcc 3.0.4

[Martin York]

Are you using exception-specifications on your methods?

The call to 
> #6  0x400a092a in __cxa_call_unexpected (exc_obj=0x81b9730) at

Suggests that you are throwing an exception that is not listed in a
callers list of valid (expected) exceptions.

eg.

#include <iostream>

struct X
{
   void test() throw (int)   // If anything but an int is thrown it will
not be caught.
   {
        throw char('a');
   }
};

int main(int argc,char *argv[])
{
    try
    {
        X  x;
        x.test();
    }
    catch(char& x)
    {
        std::cout << "Caught Char: (" << x <<")\n";
    }
    catch(int& x)
    {
        std::cout << "Caught Int: (" << x <<"(\n";
    }
    catch(...)
    {
        std::cout << "Something\n";
    }
    return(0);
}

[Joe Hughes]

try -fexceptions when compiling your application.
