[Winpcap-users] Various fixups (was: libpcap.a)

[Ouroborus]

I finally got the first step of the tutorial to compile with MingW. This took a number (7) of fixes:


1. Add "-DHAVE_REMOTE" to "CFLAGS" in the relevant make files


2. Add "../libpcap/Win32/Src/gai_strerror.o" to the object list in wpcapsrc_3_1\wpcap\PRJ\GNUmakefile


3. Copy "struct bpf_stat {...};" from wpcapsrc_3_1\Common\Packet32.h to wpcapsrc_3_1\wpcap\libpcap\pcap-bpf.h


4. Comment out "#define IN_MULTICAST..." from wpcap\libpcap\Win32\Include\ip6_misc.h


5. Add 'pcap_findalldevs_ex' to Wpcap_no_extensions.def'


6. Change line 678 in wpcapsrc_3_1\wpcap\libpcap\inet.c as per:
### Begin ###
678c678,679
<    (char*)tUstr += strlen(tAstr) + 1;;
---
> //   (char*)tUstr += strlen(tAstr) + 1;;
>    tUstr = (WCHAR*)(((char*)tUstr) + strlen(tAstr) + 1);
### End ###


7. Add file wpcapsrc_3_1\wpcap\libpcap\Win32\Src\gai_strerror.c:
### Begin ###
#define WIN32_LEAN_AND_MEAN
#include <windows.h>

#define GAI_STRERROR_BUFFER_SIZE 1024
//#define WS2TCPIP_INLINE extern inline
#define WS2TCPIP_INLINE __stdcall

WS2TCPIP_INLINE
char *
gai_strerrorA(
    IN int ecode)
{
    DWORD dwMsgLen;
    static char buff[GAI_STRERROR_BUFFER_SIZE + 1];

    dwMsgLen = FormatMessageA(FORMAT_MESSAGE_FROM_SYSTEM
                             |FORMAT_MESSAGE_IGNORE_INSERTS
                             |FORMAT_MESSAGE_MAX_WIDTH_MASK,
                              NULL,
                              ecode,
                              MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
                              (LPSTR)buff,
                              GAI_STRERROR_BUFFER_SIZE,
                              NULL);

    return buff;
}

WS2TCPIP_INLINE
WCHAR *
gai_strerrorW(
    IN int ecode
    )
{
    DWORD dwMsgLen;
    static WCHAR buff[GAI_STRERROR_BUFFER_SIZE + 1];

    dwMsgLen = FormatMessageW(FORMAT_MESSAGE_FROM_SYSTEM
                             |FORMAT_MESSAGE_IGNORE_INSERTS
                             |FORMAT_MESSAGE_MAX_WIDTH_MASK,
                              NULL,
                              ecode,
                              MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
                              (LPWSTR)buff,
                              GAI_STRERROR_BUFFER_SIZE,
                              NULL);

    return buff;
}
