I'm attempting to get a development environment up and running for developing applications with Oracle C++ Call Interface (OCCI) in Visual Studio 2005.
My system specs are: OS: Windows 7, 64-bit Oracle: 11g release 11.2.0.2, 32-bit Instant Client: BasicLite and SDK version 11.2.0.4 32-bit Visual Studio 2005 Professional Edition version 8.0 with 32-bit tools enabled
I've followed this guide by Mark Williams and I got the example running but only in release mode. When I switch to debug mode the app will build, but when I run it I get the following error:
Problem signature:
Problem Event Name: APPCRASH
Application Name: OCCITest.exe
Application Version: 0.0.0.0
Application Timestamp: 53f5dfdd
Fault Module Name: KERNELBASE.dll
Fault Module Version: 6.1.7601.18229
The small example program that triggers this error is:
#include "employees.h"
using namespace std;
using namespace oracle::occi;
int main (void)
{
Employees *pEmployees = new Employees();
delete pEmployees;
return 0;
}
Employees::Employees()
{
user = "hr";
passwd = "hr";
db = "localhost:1521/service_name";
env = Environment::createEnvironment(Environment::DEFAULT);
try
{
con = env->createConnection(user, passwd, db);
}
catch (SQLException& ex)
{
cout << ex.getMessage();
exit(EXIT_FAILURE);
}
}
Employees::~Employees()
{
env->terminateConnection (con);
Environment::terminateEnvironment (env);
}
If I remove all calls to OCCI functionality the application doesn’t crash. That is, this program runs error-free:
#include "employees.h"
using namespace std;
using namespace oracle::occi;
int main (void)
{
Employees *pEmployees = new Employees();
delete pEmployees;
return 0;
}
Employees::Employees()
{
user = "hr";
passwd = "hr";
db = "localhost:1521/service_name";
cout<<"Look at me, I'm running"<<endl;
}
Employees::~Employees()
{}
In the guide Mark mentions that when running in debug mode, the linker should use the library file oraocci11d.lib. However, this file is not included in the Instant Client SDK version 11.2.0.4, so I’m using the input file oraocci11.lib for both the release and debug version.
I'm running out of ideas about how to proceed in solving this problem, and I would greatly appreciate any and all help.
