DB- get_byteswapped: method not permitted before handle's open method

Question

Hello.
I am trying to create a C++ class that can hold a Berkeley DB object as one of its instance variables. When I call the open method, I get the error "DB->get_byteswapped: method not permitted before handle's open method".
Question: How can this error appear when I am calling the open method?
The code is like this:
---DB.h
#include <db_cxx.h>
class myClass {
private:
Db* myDb; // A pointer to my Db object
---End of DB.h
-- DB.cpp
#include <db_cxx.h>
myClass::myClass(){
myDb = new myDb(NULL,0); // Create and call my object's constructor
myDb->open(NULL, "myFile.db", NULL, DB_HASH, flags, 0); // Open the db.
--- End of DB.cpp
Thanks for any help you might provide,
Erich

Hello,
This sounds like a build problem. What version of Berkeley DB are you wanting to use? Multiple versions of Berkeley DB can be found on a system. Please check to make sure that you are not picking up a header file from a different version, or linking with with a different version. Verify your paths are not picking up multiple versions of include files, libraries. Compiling, linking, running with a combination of versions could lead to such unusual runtime results.
Thanks,
