C++ shared objects

[Suresh369]

I have written a program which inherits a calss from a different shared object. I have linked that shared object when I compile my program using the -shared <path>/blah.so

My question is how exactly do I include the parent class in my program. When I tried to use

#include<parent.h>

class child : public parent {

}

the compiler complains. The class parent is in blah.so which I am linking.

Please help

What exactly does the compiler complain about? The actual compiler message would be helpful in determining what might be the problem. Have you told the compiler where to find the include file? If it isn't in the working directory or the default include path it won't be found.

OK, I admit I dont know anything abt linking. This is the question I have.

Say I just have the .so file of another C++ program and dont have access to the source code (.h or .cpp). How do I inherit a class in my current program just by linking the .so file?

First of all, is it possible?

This is the situation I was in in the above post.

I tried to compile my program using :
g++ -shared <path>/parent.so ..... (where parent.so is the shared object)

Am I right with the command line?

You can't. You need the ".h" or ".cpp" file that contains the class definition you want to inheiret from just to compile your existing code into an object file.

i hope it will work but this is the key idea to solve it
