Hello,
I was trying to add a c-function to postgreSQL, running under cygwin.
I have installed and compiled the 8.0.0cvs from scratch, postmaster is
working fine :-)
#define _XOPEN_SOURCE
#include "postgres.h"
#include "fmgr.h"
#include <unistd.h>
#include <fcntl.h>
#include <stdio.h>
#include <sys/types.h>
#include <sys/wait.h>
PG_FUNCTION_INFO_V1(pg_crypt);
Datum
pg_crypt(PG_FUNCTION_ARGS)
{ int32 new_varchar_size=13+VARHDRSZ;
VarChar *new_t = (VarChar *) palloc(new_varchar_size);
/* ... */
PG_RETURN_VARCHAR_P(new_t);
}
compiling is successful, but linking leads to
pg_func.o(.text+0x4f):pg_func.c: undefined reference to
`__imp__CurrentMemoryContext'
If I try using pgport_palloc() instead of palloc() ( in my despair;-)
the source is compiled and linked without error but as soon as the pg_crypt
is executed from within a psql session, the postmaster crashes with signal
11.
Any Help?
Would be really great !!!
Helmut
P.S.: The function is tested and works fine under a LINUX environment
