Accessing .so libraries using dlopen() throws undefined symbol error

I'm trying to dynamically load a camera library .so file into a Linux executable to gain access to simple camera functions.

I'm attempting to do this by:

  if ( (newHandle = dlopen("./libCamera.so",RTLD_LAZY | RTLD_GLOBAL)) == NULL )
  {
     printf( "Could not open file : %s\n", dlerror() );   
     return 1;
  }

However this fails and I receive the following output: "Could not open file : libCamera.so: undefined symbol: ZTVN10_cxxabiv117__class_type_infoE"

How do I find out what symbols it is relying on?
