Thread: compiling postgres for 64 bit windows using mingw64

Hello,

I am wondering if anyone has successfully compiled postgres for 64 bit windows using mingw64?  I tried doing so but the
"configure"step fails with the following message: 

conftest.c:50: error: conflicting types for 'accept'

The config.log file shows the following additional message:

c:/mingw_64/lib/gcc../../x86_64-w64-mingw32/include/winsock2.h:1291: note: previous declaration of 'accept' was here

The definition of 'accept' in winsock2.h is: "WINSOCK_API_LINKAGE SOCKET WSAPI accept(SOCKET s, struct sockaddr *addr,
int*addrlen);", where "SOCKET" is defined as "int *".  The definition of "SOCKET" back in the 32 bit version of mingw
was"unsigned int", which appears to be what the postgres "configure" tool expects. 

Thanks in advance for any help,
Steve

We don't currently support 64-bit builds on Windows.  There are a pile
of issues there, most coming from Microsoft's nonstandard decision to
make sizeof(long) != sizeof(pointer).  In practice you probably wouldn't
get any noticeable performance improvement over a 32-bit build anyway,
seeing that large shared_buffers settings don't seem to be useful on
Windows.
