Thread: 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.

Match,
That did the trick. FWIW, my copy of time.h did not have the "#ifndef __MINGW_H" enclosures around that block.
Hopefully this'll find its way into the search engines and save somebody else the trouble.

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.

So your workaround is to downgrade to an older version of mingw. (Or do the manual header hackery that someone posted, but I'd really recommend something that works without changing the libc headers) Now that I see it again, I do think I have a patch sitting around somewhere to fix that, I guess I'll have to find and review that one. If we can't fix it, we at least need to get it into the FAQ. I'll write up a suggestion for text there if I can't get the code fixed. Unfortunately, keeping up with mingw is developing against a moving target, so these things happen :-( //Magnus
