Hi I have written a simple code in C for connecting to the queue manager.
It is getting compiled , however giving linking error . The error and make file content are follow

# make -f MQconn.mak
/usr/vacpp/bin/xlC_r -q64 -oMQconn.o -c MQconn.c
/usr/vacpp/bin/xlC_r -q64 -bloadmap:loadmap.out -oMQconn.exe MQconn.o
ld: 0711-317 ERROR: Undefined symbol: .MQCONN
ld: 0711-344 See the loadmap file loadmap.out for more information.
make: 1254-004 The error code from the last command is 8.
Stop.

When i check loadmap.out , it gives me
(ld): addgl /usr/lib/glink64.o
ADDGL: Glink code added for 13 symbols.
(ld): er full
ld: 0711-318 ERROR: Undefined symbols were found.
The following symbols are in error:
Symbol Inpndx TY CL Source-File(Object-File) OR Import-File{Shared-object}
RLD: Address Section Rld-type Referencing Symbol
----------------------------------------------------------------------------------------------
.MQCONN [24] ER PR MQconn.c(MQconn.o)
00000050 .text R_RBR [6] .main
ER: The return code is 8.

Below in my C file
#include <cmqc.h>
int main()
{
MQHCONN ConnH; /*Connection Handle */
MQHOBJ ObjH; /*Object Handle */

MQLONG CompCode; /* Completion code */
MQLONG Reason; /* Qualifying reason */

char QueMgr[] = "OIMDEV01";

strncpy(QMName,QueMgr,MQ_Q_MGR_NAME_LENGTH);

MQCONN(QMName,&ConnH,&CompCode,&Reason);

if(CompCode != MQCC_OK)
{
printf("\nMQCONN ended with Error cc %ld rc %ld\n", CompCode, Reason);
exit(Reason);
}

printf("\n Connected to queue manager");
}

Please le me know what can be the prolem here...
Thanks.
