I am Facinf the following errors when i use the header files of VBoxManage.cpp in the tstVBoxAPILinux.cpp

There are more errors with the same type with other Header files . It's not recognising the data types declared in the various Header files included in .h files.

can some one tell me where's the problem..?

Which version do you run (OSE, PUEL)? Do you run a different kernel, like KVM or Xen? Those kernel builds are not suited for VB, because they already provide virtualisation and you can't run two at the same time.

No m not running separate kernal... I dont know abt the version. M working on i386 RHEL.

Sorry, so is no help possible.

We dont know anything about ist, too. This is not a quiz show.

Provide infos (exact approach / description what you done, version, etc.).

I searched over it and now i found that i am working on the Open source edition(OSE) version. Now,can nyone tell me where's the problem in my code.

Which code? Details or forget it.

Following is the function code which m trying to run.

Code: Select all

static nsresult showInfo (nsCOMPtr <IVirtualBox> virtualBox, nsCOMPtr<IMachine> machine,
                           nsCOMPtr <IConsole> console = nsCOMPtr <IConsole> (),
                           VMINFO_DETAILS details = VMINFO_NONE)
{
    nsresult rc;
    nsCOMPtr<IMachine> machine;

    nsID uuid (argv[0]);
    if (!uuid.isEmpty())
   /* {
        CHECK_ERROR (virtualBox, GetMachine (uuid, machine.asOutParam()));
    }
    else*/
    {
        CHECK_ERROR (virtualBox, FindMachine (Bstr(argv[0]), machine.asOutParam()));
        if (NS_SUCCEEDED (rc))
            machine->COMGETTER(Id) (uuid.asOutParam());
    }
    if (NS_FAILED (rc))
        return 1;

   
    VMINFO_DETAILS details = VMINFO_NONE;
    bool fDetails = false;
    bool fStatistics = false;
    bool fMachinereadable = false;
    for (int i=1;i<argc;i++)
    {
        if (!strcmp(argv[i], "-details"))
            fDetails = true;
        else
        if (!strcmp(argv[i], "-statistics"))
            fStatistics = true;
        if (!strcmp(argv[1], "-machinereadable"))
            fMachinereadable = true;
    }
    if (fMachinereadable)
        details = VMINFO_MACHINEREADABLE;
    else
    if (fDetails && fStatistics)
        details = VMINFO_FULL;
    else
    if (fDetails)
        details = VMINFO_STANDARD;
    else
    if (fStatistics)
        details = VMINFO_STATISTICS;

    nsCOMPtr <IConsole> console;
    nsCOMPtr <ISession> session;
        rc = virtualBox->OpenExistingSession (session, uuid);
    if (NS_SUCCEEDED(rc))
        
        rc = session->COMGETTER(machine)(machine.asOutParam());
    if (NS_SUCCEEDED(rc))
        
        rc = session->COMGETTER(console)(console.asOutParam());

    rc = showInfo (virtualBox, machine, console, details);


    if (console)
        session->Close();

    return NS_SUCCEEDED (rc) ? 0 : 1;
}

But its not recogniising the datatypes of .h files like types.h , time.h etc.
if i exclude these header files from my programm then its giving the following errors:
