Update to newer C++ standard: std::auto_ptr to std::unique_ptr

[larry104]

I am using c++ 20 and I get lots of warning like that:
warning: ‘template class std::auto_ptr’ is deprecated: use 'std::unique_ptr' instead [-Wdeprecated-declarations]

It seems std::auto_ptr was deprecated in C++11 and removed in C++17. They might keep around as it seems since I compiled with C++20 and 23. But nevertheless the flood warnings coming from linking to OLA is annoying.

Any plans to update the code?

Thanks a lot!

There's a pull request to fix this, #1889, but for unknown reasons it is not getting merged. I have the feeling that the library is entering a state of being unmaintained.

I would be a shame if it would really go into the state of being unmaintained.

@larry104 we're making good progress on finishing up the lingering tasks so we can get this fixed ASAP. See #2035
