Hi,
I want to make read message on a wmq queue.
I use C++ on an Unix (SunOS) machine, and MQ Series client 5.3.0.12 .
MQ Series Client is installed in /produits/MQClient.5.3/
I want to compile a sample (amqsget0.c), but it does not work.
I use this command :
| Code: |
| gcc -o amqsget0 amqsget0.c -I/produits/MQClient.5.3/inc/ |
and i got this error :
| Code: |
Undefined first referenced
symbol in file
MQGET /var/tmp//ccDqth5W.o
MQCLOSE /var/tmp//ccDqth5W.o
MQCONN /var/tmp//ccDqth5W.o
MQDISC /var/tmp//ccDqth5W.o
MQOPEN /var/tmp//ccDqth5W.o
ld: fatal: Symbol referencing errors. No output written to amqsget0
collect2: ld returned 1 exit status |
How can i do ? |

Looks like the MQ client libraries aren't being supplied to the link step to me.....
Not used SunOS (and perhaps someone who has will kindly correct me) but I think as well as the include libraries on the -I switch, you need something like (and again I stress like):

The "Using C++" manual / information center section will provide more authoriative information. I commend it to you.

well done!
i've found a solution on :
http://publib.boulder.ibm.com/infocenter/wmqv6/v6r0/index.jsp?topic=/com.ibm.mq.amqzan.doc/amq5421.htm
it makes :
| Code: |
| gcc -o amqsget0 amqsget0.c -I/produits/MQClient.5.3/inc -L/produits/MQClient.5.3/lib -R/produits/MQClient.5.3/lib -R/usr/lib/32 -limqc23as -limqb23as -lmqic -lmqmcs -lmqmzse -lsocket -lnsl -ldl |
But, when i want to compile imqsget.cpp... i've this
| Code: |

Well the names of the missing symbols are the C++ class names. amqsget is actually a C program that uses the MQI directly (MQOPEN et al) rather than the classes.
I notice in your list of things undefined are the opperators "new" & "delete", which are C++ keyword. At the risk of sounding stupid (a risk I'm quite used to  ) are you sure this is a C++ compilation, you don't need another flag or something (as I said, not familiar with the platform).
Failing that, I would imagine you're either 1 library or some prototypes short. Do other C++ (non-MQ) compile and link ok?
