I have complied a small program :

int main()
{
DB *dbp; /* DB structure handle */
u_int32_t flags; /* database open flags */
int ret; /* function return value */

ret = db_create(&dbp, NULL, 0);
if (ret != 0) {
fprintf(stderr,"BDB create error %s\n",db_strerror(ret));
}

flags = DB_CREATE | DB_THREAD |DB_TRUNCATE;
ret = dbp->open(dbp, NULL, "/var/vx/isis/swap/gridnode.__objectdb__",
NULL, DB_HASH, flags, 0700);

if (ret != 0) {
/* Error handling goes here */
fprintf(stderr,"BDB open error %s\n",db_strerror(ret));
}

return 0;
}


I compiled it using gcc version 3.2.3 20030502 ((Red Hat Linux
3.2.3-34)) on a i686 machine which has the following configuration:

Linux x3th2 2.4.21-15.EL #1 Thu Apr 22 00:27:41 EDT 2004 i686 i686 i386
GNU/Linux

It runs fine when i execute it on this machine.When i try to run it on
a AMD x86_64 redhat machine DB open is failing with the following
error:

Function not implemented

The configuration of the redhat machine where i am running it is :
Linux xtest 2.6.9-22.ELsmp #1 SMP Mon Sep 19 18:00:54 EDT 2005 x86_64
x86_64 x86_64 GNU/Linux

Please help.

Try checking for error output, with:

dbp->set_errfile(dbp, stderr);

before the DB->open call.

Thanks Michael .
The error is now getting printed as :

unable to initialize mutex: Function not implemented
process-private: unable to initialize environment lock: Function not
implemented

What could be done to fix this?

I see that if i compile my program on this machine(x86_64) and then
everything works fine.
but the same problem compiled on i686 gives me the above errors

got the problem !!

The machine had LD_ASSUME_KERNEL set to 2.4.19.This was causing the
program to pick up older versions of libpthread. which possibly did not
support pthread mutexes.
After i unset it things worked fine.

Thanks for the help
