Syslog link errors

David E. Cross — Tue, 03 Jul 2007 04:15:29 GMT

Hi,

I'm new to OpenVMS and getting to grips with the ONC RPC examples. My code works but I get 'undefined symbol SYSLOG' emanating from the RPC libraries. Should I have included some standard library or set up some default which is so obvious that nobody bothers to document it?

Dave,

I have no idea what you mean by "THE" ONC RPC examples. The RPC examples provided with HP TCP/IP V5.4 (in SYS$COMMON:[SYSHLP.EXAMPLES.TCPIP.RPC]) build cleanly on my OpenVMS ALpha V7.3-2 system.

So, obviously you mean some ONC RPC examples you've brought over from *ix. If that's the case, the answer is: there is neither a syslog() system function in OpenVMS' C RTL, nor is there a syslogd provided with the OS.

That said, you can build your own syslogd, see e.g. http://vms.process.com/scripts/fileserv/fileserv.com?SYSLOGD (the site seems to be down at the moment).

HTH,
Martin

I meant the examples in the text of the doc 'HP TCP/IP Services for OpenVMS - ONC RPC Programming'.

I've found out that OpenVMS doesn't have a Syslog whcih confuses me even more.

Dave,

I just looked through the examples in chapter 2 (http://h71000.www7.hp.com/doc/82FINAL/6528/6528pro_001.html#rpcgen_chap), but the code for those is in SYS$COMMON:[SYSHLP.EXAMPLES.TCPIP.RPC] and doesn't have a call to syslog().

Which specific example are you refering to?

Hi,

Stripped to the bare bones, this is the problem.

EV6::DEH.DINTSRC> type mintest.c
/* Mintest.c */

#include /* always needed */
/* partial contents of RPCGEN generated file copied below */
//#include "TCPIP$RPC:TYPES.H"
#define MYSERVER ((u_long)0x20000017)
#define MYSERVERVER ((u_long)1)

main(argc, argv) int argc; char *argv[];
{
CLIENT *cl;
cl = clnt_create("EV6", MYSERVER, MYSERVERVER, "tcp");
exit(0);
}

Dave,

which version of TCPIP and on which architecture:

$ TCPIP SHOW VERSION

This would smell like a bug in TCPIP, if they would deliver a version of TCPIP$RPCXDR.OLB with external references to SYSLOG... - did you try linking with the shareable image SYS$SHARE:TCPIP$RPCXDR_SHR as described in the documentation ?

Yes, it does appear the object library has a goof or there is something missing from your linker search path. You should log a call if you have a support contract. If you don't have any special requirement that mandates static linking, you can link against the shareable image (aka dynamic library) instead. To do that, just create a linker options file and add it to your link command like so:

$ type mintest.opt
SYS$SHARE:TCPIP$RPCXDR_SHR/SHARE
$ link mintest,mintest/options

Or specify it directly on the command line/in the build DCL procedure file:

$ link mintest,sys$input:/options
SYS$SHARE:TCPIP$RPCXDR_SHR/SHARE
$

Thanks Guys,

Using the shareable library solved the problem.

For reference Show Version reports:

HP TCP/IP Services for OpenVMS Alpha Version V5.5 - ECO 1
on an AlphaServer DS20 500 MHz running OpenVMS V8.2
