需要建议来尝试构建此应用程序（运行 出现 2 个错误）
Need advice trying to get this app to build (running into 2 errors)
我正在尝试将 Dolphin 模拟器中的一项功能实现到非官方版本中，同时自己学习 C++ 编码。现在我能够减少一个文件的错误数量，但这些是我得到的错误。
第一个代码错误是这样的：
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;
我在引用“std::min " 它也出现在这里：
const u64 bytes_to_write = std::min(bytes_to_write_total, VolumeWii::GROUP_DATA_SIZE);
错误 = (C:\Users\Desktop\dolphin\Source\Core\DiscIO\WIABlob.cpp:1488:42: 错误: 没有匹配的函数来调用 'min')
---------------------------------------- ------------------------------------
我得到的下一个错误（同样所有这些都在同一个 .cpp 文件中）也来自相同的代码行：
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;
还有这里：
const u64 bytes_to_write = std::min(bytes_to_write_total, VolumeWii::GROUP_DATA_SIZE);
我在后面的设置中得到的错误是 [C:\Users\Desktop\dolphin\Source\Core\DiscIO\WIABlob.cpp:1465:21: 错误：const 类型 'const u64' 对象的默认初始化（又名 'const unsigned long')] --> 这是 Android Studio 中“bytes_to_write”行的 related/highlighted。
也出现在下方仍然与另一个“bytes_to_write”行相关 [C:\Users\Desktop\dolphin\Source\Core\DiscIO\WIABlob.cpp:1488:25: error: default initialization of an object of const type 'const u64' (aka 'const unsigned long')]
到目前为止，这些是阻止我构建应用程序的 2 个错误。

如果您想从这里的 .cpp 文件中查看我正在使用的原始代码：
https://github.com/JosJuice/dolphin/blob/660d81a10b4a8ff9a61631e69fb93e9010bccbc0/Source/Core/DiscIO/WIABlob.cpp
我希望我能得到任何好的建议来解决这个问题并最终构建 Apk（现在已经坚持了几个星期）
你的错误信息应该很清楚了。相关部分：
../../../../../../Core/DiscIO/WIABlob.cpp:1465:39: error: no matching function for call to 'min'
const u64 bytes_per_chunk = std::min(out_data_per_chunk, VolumeWii::GROUP_DATA_SIZE);
^~~~~~~~

min(const _Tp& __a, const _Tp& __b)
关键部分是您将不同的类型传递给 std::min，这是不允许的（想想 return 类型会是什么）。您需要将一个参数转换为另一种类型，或者您可以明确说明您想要哪个版本的 std::min。
转换看起来像这样：
const u64 bytes_per_chunk = std::min(out_data_per_chunk, static_cast<unsigned long>(VolumeWii::GROUP_DATA_SIZE));
显式调用版本如下所示：
const u64 bytes_per_chunk = std::min<u64>(out_data_per_chunk, VolumeWii::GROUP_DATA_SIZE);
