Thanks for reply Tom!
I've tried several version:
#define _USE_32BIT_TIME_T
#include "postgres.h"
#include "fmgr.h"
#include "executor\spi.h"
/*
#ifdef PG_MODULE_MAGIC
PG_MODULE_MAGIC;
#endif
*/
extern Datum count_person (PG_FUNCTION_ARGS);
PG_FUNCTION_INFO_V1(count_person);
__declspec(dllexport)
Datum count_person(PG_FUNCTION_ARGS) {
int32 ret;
SPI_connect();
ret = SPI_exec("SELECT count(*) FROM person", 0);
SPI_finish();
PG_RETURN_INT32(ret);
}
but still the same error occurs.
I also tried to include pgmagic.h, which I found in here:
http://archives.postgresql.org/pgsql-committers/2006-05/msg00369.php
http://anoncvs.postgresql.org/cvsweb.cgi/pgsql/src/include/Attic/pgmagic.h?rev=1.1&content-type=text/x-cvsweb-markup
but this produces a compiler error:
G:\PostgreSQL\8.3\include\server\pgmagic.h|40|error: conflicting types for 'Pg_magic_struct'|
G:\PostgreSQL\8.3\include\server\fmgr.h|367|error: previous declaration of 'Pg_magic_struct' was here|

G:\PostgreSQL\8.3\include\server\fmgr.h|370|warning: this is the location of the previous definition|
||=== Build finished: 4 errors, 4 warnings ===|
I tried to build it in Visual C++ Express 2010 but compiler error occur (SPI_connect())
Any Idea to solve the problem ?
