I modified the programm amqsput0.c to be able to put a complete file toto.txt in a queue. I imported the library mqm.lib.
When I try to build the amqsput0.c file, I get an error : undefined reference to "MQCONN" and this message for all MQ command.
Any idea ?

Probable cause would be that mqm.lib is not linked properly or are using the wrong version of it. Are you using C compiler from command prompt, or are you using Visual Studio. If you are using the latter you need to add mqm.lib to project->settings->link->library module.
Cheers.

That's exactly the problem. This library isn't linked properly. But I don't use Visual Studio and I don't build my programs from the prompt. My compiler is called Dev-C++ 4 by "Bloodshed". It's a freeware. Do you know it?
I have copied the file called mqm.LIB in the Dev-C++ lib directory and I've still got the same error message given by the linker : "undefined reference to "MQCONN", undefined reference to "MQOPEN", etc...
What could be the solution? Thanks. |

Hi!
Thank you for your tip but it still doesn't work. I have built this program with another compiler and ther's the same problem. So, I tried to build a source file of an executable supplied by MQSeries and there's the same linker errors again. I'm really lost... |

Hi,
1) In the LIB Environment variable add "X:...MQSeriestoolslib"
2) In the INCLUDE Environment variable add "X:..MQSeriestoolscinclude;X:..MQSeriestoolscplusinclude;"
Where X is the drive and directory where MQSeries is installed
Regards
Ved

There's no LIB variable on my system and I'm not allowed to create any (I'm not the administrator). Is there another solution?
Thank you for your help. |

If you are running from the prompt using your DEV C++ compiler, there should be a flag to supply Library paths. Check the compiler flags through it's help. If it is an IDE, then there must be a way out in it to specify the Library paths.
Check them out.
Hope this helps.
Cheers.
Kumar

Well reading your subject you used the word CLIENT does that mean you have MQ Client installed, if so the correct lib to link on NT is mqic32.lib not mqm.lib

Sorry for having made you wait for my answer.
I'm using Windows 2000. Finally, I've found the environment variable LIB and I set it like you told me.
I have checked all the Libraries paths on my IDE. And with the mqic32.lib there is the same errors. I'm beginning to think that someone put a spell on me to prevent me to work.
I'm really lost. I've never met such a strange problem and I have built thousands of programs yet!
Once again thank you so much for trying to help me! |

One of the c++ features of have the same function name with different parameters
requires the function names be modified at link link time to some mangled name
This is just a made up sample to give you and idea about mangling, actual mangled names look real strange and every c++ compiler appears to do it differently (bright idea)
ie add(int,int)
add(long,long)
mangled names addINT
addLONG
Check cmqc.h header file find the following
does your c++ compiler generate the ___cplusplus symbol if so then name mangling isnt the issue if not then remove the if defined
#if defined(__cplusplus)
extern "C" {
#endif

OK, I am going to add to that lengthy discussion... 
I just downloaded the compiler and tried it; with no problems.
If you open the Project options (Alt-P), you will see an entry field at the bottom titled: 'Linker Options/Optional Libs or Object files'. If you put in c:msmqctoolslibmqic32.lib, replacing the path with your path to the library, it should work.
Cheers,
Stefan
