这是我第一次使用cygwin gcc，之前我在linux上使用过它。 我遇到了一个我在网上找不到的问题解决方案。
我想编译C源文件并包含此源
// Value type defenitions
// --- chars --- //
typedef unsigned char UChar;
typedef char Char;
// --- short int --- //
typedef unsigned short UShort;
typedef short Short;
// --- int --- //
typedef unsigned int UInt;
typedef int Int;
// --- long int --- //
typedef long Long; // 32 bits length
typedef unsigned long ULong; // unsigned 32 bits length
// --- long long int --- //
typedef unsigned long long UBig; // 64-bit length unsigned
typedef long long Big; // 64-bit length
// --- decimals --- //
typedef float Float;
typedef double Double;
typedef long double Triple; // 80-bit length. Actual properties unspecified.
并且出现了此错误
Include/null.h:6: error: redefinition of typedef 'UChar'
Include/null.h:6: error: previous declaration of 'UChar' was here
Include/null.h:7: error: redefinition of typedef 'Char'
Include/null.h:7: error: previous declaration of 'Char' was here
Include/null.h:9: error: redefinition of typedef 'UShort'
Include/null.h:9: error: previous declaration of 'UShort' was here
and so on...
谢谢你的帮助！
