Re: [PORTS] Compilation failure: 8.2.4 and 8.1.0 under XPPro/MinGW

Phil,

I found the same problem. It seems that MinGW has a broken header file. I made the following changes:

In MinGW/include/sys/time.h

• Cut here ------------
  #ifndef __MINGW_H
  /* Provided for compatibility with code that assumes that the presence of gettimeofday function implies a definition of struct timezone. */ struct timezone { int tz_minuteswest; /* of Greenwich */ int tz_dsttime; /* type of dst correction to apply */ };

/*

   Implementation as per:
   The Open Group Base Specifications, Issue 6    IEEE Std 1003.1, 2004 Edition

   The timezone pointer arg is ignored. Errors are ignored. */
int __cdecl gettimeofday(struct timeval *__restrict__,

                         void *__restrict__ /* tzp (unused) */);
#endif

--------- Cut here ------------

This is not documented anywhere. On the postgres site or the mingw sites.
Hope that helps.

Match

Subject: [PORTS] Compilation failure: 8.2.4 and 8.1.0 under XPPro/MinGW

I've seen the build error below referenced in several messages, but haven't seen a clear answer for how to resolve it.

Environment: XP Pro with MSys/MinGW freshly installed according to the docs here: http://www.postgresql.org/docs/faqs.FAQ_MINGW.html Zlib is installed; Visual Studio and Cygwin are also on the system but should be out of the way.

Reason for building: increase NAMEDATALEN so it'll quit truncating my absurdly-large column names.

Output from Make (substantially the same whether I'm building 8.2.4 or 8.1.0):

Could someone please provide either:
* Better instructions for how to install/configure MSys and MinGW or * Better instructions for how to compile Postgres using MinGW?
