Re: C++ program with C shared object?

[Joshua Pollak <joshp at cra dot com>]

Thank you,

I finally got the program to compile by using gcc to call the linker, and 
specifying -lstdc++ as well. Now I have one more problem. My goal is to 
have the library call a callback function from the executable. This 
callback function will throw an exception, which will be caught by the 
function in the application that initially called the shared library. The 
goal is to create an Exception based error handling system, even though the 
shared object is written in C, not C++.

The same code base works as a Windows C DLL and C++ Program, so I'm sure 
I'm just missing a compiler flag or something.

Both the library and program are compiled with the command line options 
-fexceptions -frtti

But at the point where the exception should have been thrown, I only see 
the text, 'Aborted' on stdout, although that phrase is not in my source 
code at all.

Is the library having trouble calling the callback function, or is 
the  exception having trouble making its way through the C library back to 
the application?

Again, thanks to the response to the initial question, and thank you for 
any help you can lend me.
