c++ - 从limemicro编译lms6suite时出现枚举错误

Question

我刚刚从https://github.com/limemicro/lms6suite从lime Microsystem下载了lms6002的控制软件。
我尝试编译但出现错误

这里是有问题的头文件:

 16                 void Initialize( ConnectionManager *pControl);

 46 
 47                 DECLARE_EVENT_TABLE()
 48 };

 50 #endif

复制步骤:

git clone https://github.com/limemicro/lms6suite lms6suite
cd lms6suite
cd build
cmake ../
make

有人可以告诉我这是哪里来的吗？

非常感谢:)

问题几乎可以肯定是由于使用“状态”一词作为枚举的名称。该名称会导致编译器错误，因为Xlib.h(显然间接包含在上述程序中)包含以下行:

#define Status int

因此，在预处理之后，定义为:

enum int { SUCCESS, FAILURE };

这是无效的C++。最好重命名该枚举。
