我正在我的 macOS Catalina 10.15.6（使用 Apple clang 版本 12.0.0 (clang-1200.0.32.2)）上编译 Apache ORC，这里有一些错误。请问是什么原因造成的？

附：以下是我运行 cmake 的方式：cmake -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DOPENSSL_LIBRARIES=/usr/local/opt/openssl/lib ..

【问题讨论】：

问题的根源是源代码使用了marco，这是一个C++关键字名称，是一个警告，并且类的构造函数有返回类型，这是语法错误。

Apache ORC 的确切版本是什么？你修改过源代码吗？

【参考方案1】：

_LIBCPP_CONSTEXPR 是 LibCxx 标准库编译器定义。 你的兽人库代码的定义与编译器定义冲突，所以在这个文件中/Users/karlkatzen/Documents/code/orc/c++/src/Adaptor.hh:177:9: error: keyword is hidden by macro definition [-Werror,-Wkeyword-macro] #define constexpr const 只需评论此行#define constexpr const。
