I'm trying to use the fix from 'int8_t' : redefinition error in config.h when trying to connect mysql cpp connector to visual studio 2010 which suggests setting a macro
我正在尝试使用'int8_t'中的修复：在尝试将mysql cpp连接器连接到visual studio 2010时，在config.h中重新定义错误，建议设置一个宏
HAVE_INT8_T=1
HAVE_INT8_T = 1
I know how to use the Preprocessor to define variables, but in that case, I would have expected the answer to be in the form
我知道如何使用预处理器来定义变量，但在这种情况下，我希望答案可以在表单中
#define HAVE_INT8_T 1
#define HAVE_INT8_T 1
Is this an equivalent suggestion? Or do I need to set the macro in a project settings menu somewhere?
这是一个相同的建议吗？或者我是否需要在某个项目设置菜单中设置宏？
If so, I've read the documentation for Property Pages, but I can't locate the Macros menu. A screenshot would be helpful, if this is the way I need to go.
如果是这样，我已阅读Property Pages的文档，但我无法找到Macros菜单。如果这是我需要的方式，屏幕截图会有所帮助。

The scope is different if you declare it into the property pages for the entire Project or into just one file:
如果将其声明为整个Project的属性页或仅声明一个文件，则范围会有所不同：
If you need that into one file only (or if you're comfortable with a header for that), go for it. Otherwise do it at project scope.
如果您只需要将其放入一个文件中（或者如果您对标题感到满意），那就去吧。否则在项目范围内进行。
