regarding .so files and dynamic linking

[pratap]

Is there any way in which one can link a.so(Class implementation by
Vendor A in a dynamic library) and b.so(Class implementation by Vendor
A in a dynamic library) and use it in 1.cpp
where 1.cpp
would contain
int main()
{
A a,Bb
return 0;
}

The idea here is to instantiate class object a from class A which is
defined in a.so and class object b from class B which is defined in
b.so.

This is off-topic here since it's vendor-dependent, but usually you
have to include some files, like a.h and b.h, so 1.cpp would look
something like:

#include "a.h" // or perhaps <a.h>
#include "b.h"

int main()
{
A a;
B b;
}

The rest is then up to the linker.

Does not work
Have tried that

Don't quote signatures.

Does not work

What happens? Doesn't compile? doesn't link? compiles and links but
doesn't run correctly? Makes computer explode?

Have tried that

Tried what??? What did you do to compile/link/run?

How can we help you if you don't give us any information?

SUCCESS!!!

tried

gcc -rdynamic -o 1 1.cpp -L/path of so files/ -la -lb
where -la and -lb are liba.so and libb.so
and it worked.
was using the wrong flags while making.
