Need advice trying to get this app to build (running into 2 errors)

26th September 2020 android-studio, android-studio-2.3, android-studio-3.0, c++

I’m trying to implement a feature found in Dolphin emulator into an unofficial build while learning about C++ coding on my own. Right now I was able to decrease the amount of errors to one file but these are the errors that I am getting for it.

First code errors are for this:

const u64 bytes_per_chunk = std::min(out_data_per_chunk, VolumeWii::GROUP_DATA_SIZE);
      const u64 total_size = blocks_in_this_group * VolumeWii::BLOCK_DATA_SIZE;
      const u64 data_offset = parameters.data_offset + write_offset_of_group;

I get an error that says "No matching function for call to min" when referring to the " std::min " It appears in here as well:

const u64 bytes_to_write = std::min(bytes_to_write_total, VolumeWii::GROUP_DATA_SIZE);

The next error I get (again all this is within the same .cpp file) is also from the same lines of code:

const u64 bytes_per_chunk = std::min(out_data_per_chunk, VolumeWii::GROUP_DATA_SIZE);
      const u64 total_size = blocks_in_this_group * VolumeWii::BLOCK_DATA_SIZE;
      const u64 data_offset = parameters.data_offset + write_offset_of_group;

and here too:

const u64 bytes_to_write = std::min(bytes_to_write_total, VolumeWii::GROUP_DATA_SIZE);

The error I get for the later set is " default initialization of an object of const type ‘const 64’ (aka ‘const unsigned long’) " –> this is related/highlighted by the "bytes_to_write" line in Android Studio.

So far those are the 2 errors that stop me from building the app.
