Problem with calling from Unity

[cybie]

I am trying to call Camera SDK from Unity.

However, when I called a DLL function it die trying to create the single CameraManager::X()

In singleton.h

Code: Select all

        static T& X()
        {
            if (m_instance == 0) 
            {
                if(m_Lock==0)
                    m_Lock = new LockItem();

                m_Lock->Lock();
                if(m_instance==0)
                {
                    m_instance = new T; // << Die here
                }
                m_Lock->UnLock();
            }

            return *m_instance;
        };

The "new T" was successful in allocating memory, but failed to continue to go to next line. So I suspect it might be dying in the constructor.

Any Ideas?

Thanks

I'm not entirely sure what the issue is here but would love to know the answer.

For the Camera SDK the run-time is statically linked. Perhaps that is the problem. If anyone has any additional insight, I would like to track this down so that our Camera SDK will place nice with Unity.

Hi Doug,

I am not sure if that is the problem, but is it possible for you to release the Camera SDK as dynamically linked DLL?

Thanks

Email support and I'll have them send you a dynamically linked DLL, hopefully that will solve the problem. I will likely add this build to the installer so it's available to everyone.

Hi Doug,

I have contacted the support through the support contact form. I am still waiting for the library.

Thanks

A link to the library should be in your mail.

Hello! I have the same problem here!

I have created a dll I want to call from another program but it dies at singleton creation.
The weird thing is that it works sometimes if I put a printf instruction before creating the singleton. Unfortunately, this is not an acceptable solution.

Have you found any solution? Can I also have an access to that dll please?
