我试图将宏用于＆＃34; pragma include_alias＆＃34;在VS2010中，但是我得到了一个奇怪的编译警告，这意味着替换是不正确的。 这是代码：
18 #define RAPID_INCLUDES_PATH(MY_TARGET_HEADERS) "C:\\thirdpart\\rapidxml-1.13\\" ## #MY_TARGET_HEADERS
19 #define TEST(empty) "C:\\thirdpart\\rapidxml-1.13\\rapidxml_print.hpp"
//WORKS
21 #pragma include_alias( "rapidxml.hpp", "C:\\thirdpart\\rapidxml-1.13\\rapidxml.hpp" )
22 #pragma include_alias( "rapidxml_print.hpp" , TEST(empty) )
//FAILS
23 #pragma include_alias( "rapidxml_utils.hpp" , RAPID_INCLUDES_PATH(rapidxml_utils.hpp) )
24 #pragma include_alias( "rapidxml_iterators.hpp" , RAPID_INCLUDES_PATH(rapidxml_iterators.hpp) )
26 #include "rapidxml.hpp"
27 #include "rapidxml_iterators.hpp"
28 #include "rapidxml_print.hpp"
29 #include "rapidxml_utils.hpp"
错误消息：
1> Touching "Debug\xml2.unsuccessfulbuild".

似乎有一些误用宏 任何人都知道如何解决它？非常感谢。
