我正在尝试使用使用 g++ 的示例库 Mocapy++。

通过调用安装时cmake .出现此错误：

-- Boost version: 1.52.0
-- Boost version: 1.52.0

现在，如果我尝试调用make我会得到错误：

请让我知道该怎么做。谢谢！

CMake 过程中没有错误（似乎您可以忽略有关找不到 Boost 的多条消息）。

但是Mocapy++ 代码中有一个错误，它试图使用 min/max 而不是 std::min/std::max，这就是编译失败的原因（并且在最新版本中仍然失败）。

如果你想修复它，编辑src/utils/mdarray.h，找到MDArray<T>::clip函数并替换这两行：

values[i] = max(minimum, values[i]);
values[i] = min(maximum, values[i]);

和：

values[i] = std::max(minimum, values[i]);
values[i] = std::min(maximum, values[i]);

输入“make”，等待并享受 :)
