Redefinition and other errors
in [Win32 API]
|
From: Rayne on 8 Dec 2009 22:39 Hi all, I'm sorry, but this is going to be a long post, because I'm trying to be as detailed as possible. I'm running the code on Visual Studio .NET 2003. The entire project has 28 header files, and corresponding .c files where applicable. I'm new to programming in Windows, and I'm getting confused with all the different Windows header files that seem to be causing these errors. I'm going to split the post into 2 since it is long. The 28 self-defined header files (A.h - Z.h, AA.h, BB.txt) are listed below, showing what other header files are included. All header files have #include guards. A.h ---- #include <WinSock2.h> #include <Ws2tcpip.h> #include <windows.h> #include <stdio.h> #include <stdlib.h> #include <pthread.h> #include <string.h> #include <curses.h> #include <tchar.h> #include <strsafe.h> #include "X.h" #include "AA.h" #include "R.h" B.h ---- #include "X.h" #include "M.h" C.h ---- #include <WinSock2.h> #include <windows.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include "M.h" D.h ---- No #includes E.h ---- #include <windows.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <tchar.h> #include <strsafe.h> #include "D.h" #include "R.h" F.h ---- #include <stdio.h> #include <stdlib.h> #include <string.h> #include <ctype.h> G.h ---- #include <time.h> #include <curses.h> #include <pthread.h> #include <time.h> #include <pcap.h> #include "A.h" H.h ---- #include <WinSock2.h> #include <windows.h> #include <stdio.h> #include <stdlib.h> #include <pcap.h> #include <string.h> #include <strsafe.h> #include <signal.h> #include "D.h" #include "U.h" #include "F.h" #include "BB.txt" #include "M.h" #include "R.h" I.h ---- #include "V.h" #include "Y.h" #include "K.h" #include "J.h" J.h ---- #include <stdlib.h> #include <vector> #include "X.h" K.h ---- #include <WinSock2.h> #include <Ws2tcpip.h> #include <stdio.h> #include <string.h> #include "L.h" #include "X.h" L.h ---- #include <stdio.h> #include <stddef.h> #include <stdlib.h> M.h ---- #include <WinSock2.h> #include <ws2tcpip.h> #include "X.h" N.h ---- #include <winsock2.h> #include <windows.h> #include <pthread.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include "X.h" #include "A.h" #include "P.h" O.h ---- #include <windows.h> #include <tchar.h> #include <stdio.h> #include <pcap.h> #include <pthread.h> #include <strsafe.h> #include "Z.h" #include "K.h" P.h ---- #include <WinSock2.h> #include <Windows.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <errno.h> #include <ctype.h> #include <time.h> #include <fcntl.h> #include "X.h" Q.h ---- #include <stdlib.h> #include <pthread.h> #include <vector> #include <algorithm> #include "K.h" #include "V.h" #include "C.h" #include "S.h" #include "I.h" R.h ---- #include <windows.h> #include <tchar.h> #include <stdio.h> #include <strsafe.h> S.h ---- #include <stdlib.h> #include <stdio.h> #include <windef.h> T.h ---- #include <stdio.h> #include <stdlib.h> #include <string.h> #include <pthread.h> #include <pcap.h> #include <signal.h> #include <strsafe.h> #include "V.h" #include "Y.h" #include "W.h" #include "Q.h" #include "N.h" #include "G.h" #include "A.h" U.h ---- #include <stdio.h> #include <stdlib.h> #include <string.h> #include <ctype.h> V.h ---- #include "K.h" #include "O.h" #include "B.h" #include "I.h" #include "M.h" W.h ---- #include <stdlib.h> #include <time.h> #include <pthread.h> #include "K.h" #include "Q.h" X.h ---- No #includes Y.h ---- #include "K.h" #include "O.h" #include "B.h" #include "S.h" #include "I.h" #include "M.h" Z.h ---- #include <Windows.h> #include <time.h> #include "X.h" AA.h ----- #include <WinSock2.h> #include <WS2tcpip.h> #include <Windows.h> BB.txt ------- No #includes
From: Rayne on 8 Dec 2009 22:41 I'm getting mostly redefinition errors that point to Winsock2.h and WS2tcpip.h. They all refer to "see previous definition if '<variable>'" in WinSock.h. I'm also getting errors (not redefinition) that point to WSPiAPi.h, even though this file is not explicitly #included by me. There are over a hundred errors, and I'm showing the representative ones: error C2011: 'fd_set' : 'struct' type redefinition error C2011: 'hostent' : 'struct' type redefinition error C2011: 'ip_mreq' : 'struct' type redefinition error C2011: 'linger' : 'struct' type redefinition error C2011: 'timeval' : 'struct' type redefinition error C2011: 'WSAData' : 'struct' type redefinition error C2375: 'accept' : redefinition; different linkage error C2375: 'bind' : redefinition; different linkage error C2375: 'connect' : redefinition; different linkage error C2375: 'gethostbyname' : redefinition; different linkage error C2375: 'gethostname' : redefinition; different linkage error C2375: 'htonl' : redefinition; different linkage error C2375: 'inet_addr' : redefinition; different linkage error C2375: 'inet_ntoa' : redefinition; different linkage error C2375: 'WSAAsyncGetHostByAddr' : redefinition; different linkage error C2375: 'WSAStartup' : redefinition; different linkage error C2440: '=' : cannot convert from 'char *(__stdcall *)(in_addr)' to 'char *' error C2440: '=' : cannot convert from 'char *(__stdcall *)(in_addr)' to 'char *' There is no context in which this conversion is possible error C2440: '=' : cannot convert from 'hostent *(__stdcall *)(const char *)' to 'hostent *' error C2440: '=' : cannot convert from 'hostent *(__stdcall *)(const char *)' to 'hostent *' There is no context in which this conversion is possible error C2440: '=' : cannot convert from 'servent *(__stdcall *)(const char *,const char *)' to 'servent *' error C2440: '=' : cannot convert from 'servent *(__stdcall *)(const char *,const char *)' to 'servent *' There is no context in which this conversion is possible error C2440: '=' : cannot convert from 'u_long (__stdcall *)(u_long)' to 'DWORD' error C2440: '=' : cannot convert from 'u_long (__stdcall *)(u_long)' to 'DWORD' This conversion requires a reinterpret_cast, a C-style cast or function-style cast error C2450: switch expression of type 'int (__stdcall *)(void *) is illegal Integral expression required error C3861: 'gethostbyaddr': identifier not found, even with argument- dependent lookup error C3861: 'getservbyname': identifier not found, even with argument- dependent lookup error C3861: 'htonl': identifier not found, even with argument- dependent lookup error C3861: 'htons': identifier not found, even with argument- dependent lookup error C3861: 'inet_ntoa': identifier not found, even with argument- dependent lookup error C3861: 'inet_addr': identifier not found, even with argument- dependent lookup error C3861: 'ntohs': identifier not found, even with argument- dependent lookup error C3861: 'WSAGetLastError': identifier not found, even with argument-dependent lookup warning C4005: 'AF_IPX' : macro redefinition warning C4005: 'AF_MAX' : macro redefinition warning C4005: 'FD_ACCEPT' : macro redefinition warning C4005: 'FD_CONNECT : macro redefinition warning C4005: 'IP_ADD_MEMBERSHIP' : macro redefinition warning C4005: 'IP_DROP_MEMBERSHIP' : macro redefinition warning C4005: 'IP_TOS' : macro redefinition warning C4005: 'SO_DONTLINGER' : macro redefinition warning C4005: 'SOMAXCONN' : macro redefinition I don't know why I'm getting these errors, and I would greatly appreciate any help I can get. Thank you! Regards, Rayne

Everywhere you use any Windows API stuff. Cheers & hth., - Alf
From: Rayne on 9 Dec 2009 04:04 I added the Command Line Option /D_WINSOCKAPI_ and can now compile and run the program. Thank you for all your help!
