我正在使用VS2012 ARM Cross Tools命令提示符从命令行编译源代码。我发现我需要添加_ARM_WINAPI_PARTITION_DESKTOP_SDK_AVAILABLE才能让项目开始编译。
许多文件干净地编译。例如：
cl /Fotmp32dll\fips_drbg_selftest.obj -Iinc32 -Itmp32dll /MD /Ox /O2 /O
b2 -DOPENSSL_FIPSCANISTER -DOPENSSL_THREADS -DDSO_WIN32 -D_ARM_WINAPI_PARTITIO
N_DESKTOP_SDK_AVAILABLE -DOPENSSL_USE_APPLINK -I. -DOPENSSL_NO_RC5 -DOPENSSL_NO_
MD2 -DOPENSSL_NO_KRB5 -DOPENSSL_FIPS -DOPENSSL_NO_JPAKE -DOPENSSL_NO_STATIC_ENGI
NE /Zi /Fdtmp32dll/lib -D_WINDLL -c .\fips\rand\fips_drbg_selftest.c

现在我遇到了一个宏重定义问题（在编译了大约25个文件之后）：
C:\Program Files (x86)\Windows Kits\8.0\include\shared\ws2def.h(96) : warning C4
005: 'AF_IPX' : macro redefinition
C:\Program Files (x86)\Windows Kits\8.0\include\um\winsock.h(452) : see
previous definition of 'AF_IPX'
C:\Program Files (x86)\Windows Kits\8.0\include\shared\ws2def.h(136) : warning C
4005: 'AF_MAX' : macro redefinition
C:\Program Files (x86)\Windows Kits\8.0\include\um\winsock.h(471) : see
previous definition of 'AF_MAX'
...
C:\Program Files (x86)\Windows Kits\8.0\include\shared\ws2def.h(217) : error C20
11: 'sockaddr' : 'struct' type redefinition
C:\Program Files (x86)\Windows Kits\8.0\include\um\winsock.h(477) : see
declaration of 'sockaddr'
...
我发现INCLUDE envar同时包含include\shared和include\um个路径：
INCLUDE=C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\INCLUDE;C:\Progra
m Files (x86)\Microsoft Visual Studio 11.0\VC\ATLMFC\INCLUDE;C:\Program Files (x
86)\Windows Kits\8.0\include\shared;C:\Program Files (x86)\Windows Kits\8.0\incl
ude\um;C:\Program Files (x86)\Windows Kits\8.0\include\winrt;
当我看到差异时，警告是次要的：
// shared/windosck.h
#define AF_IPX 6 /* IPX and SPX */
#define AF_NS 6 /* XEROX NS protocols */
// um/ws2def.h
#define AF_NS 6 // XEROX NS protocols
#define AF_IPX AF_NS // IPX protocols: IPX, SPX, etc.
但错误存在重大差异：
// shared/ws2def.h:
typedef struct sockaddr {
#if (_WIN32_WINNT < 0x0600)
u_short sa_family;
#else
ADDRESS_FAMILY sa_family; // Address family.
#endif //(_WIN32_WINNT < 0x0600)
CHAR sa_data[14]; // Up to 14 bytes of direct address.
} SOCKADDR, *PSOCKADDR, FAR *LPSOCKADDR;
// um/winsock.h
struct sockaddr_in {
short sin_family;
u_short sin_port;
struct in_addr sin_addr;
char sin_zero[8];
};
include\shared和include\um之间的区别是什么？
