Hi,
First, a problem description:
I have written an application using the MQ C++ API and linked against the client version of the mq lib. the program works fine on computers with MQ client / MQ server installed.
Since this program is to be deployed on hundreds of windows workstations, the customer has expressed that it is a lot of work to install the MQ client installation on all the workstations. So I'm investigating if it is possible to extract the necessary MQ DLL files from an MQ Client installation and "ship" them with the appliaction in question. I have listed the dependancies for my application and included all the MQ DLL files referenced.
When trying to run the program on a machine with no MQ installation what so ever (as intended) I get the following error message on the console:
MQM could not display the text for error 536895891.
And also MQ result code 2195 (resolved to: unknown error)
I read in an earlier post that it might not be possible to accomplish a working solution by extracting the necessary DLL files from a client installation. - Is this true? It sure begins to look that way...
Now, I know it is easy to say "why don't you install the MQ client? it's free" - that is not the problem. It has to be installed on a couple of hundred hosts... So it would be very nice if this could work somehow..
What do you gurus think? theoretically and practically?
Have anyone succeeded in doing this?
Regards,

I wouldn't trust anything other than a full MQ client install.
If I were facing your requirements, I would write my app in Java, and include the MQ jar files in my jar. The Java client API is 100% pure java, and fully portable. The C++ API is not.

| Why not use silent installation? Write a simple script to silent install MQ Clients, put installation on some LAN drive, and run from all said workstations; I've never tried it with a client installation, but it should work. |

| Since you seem to have a big network, you could be having tools for mass installs. If you do package based install(script oriented) it could be fast and easy. If those are windows based machines, tools like netdeploy r handy. Cheers.... |

Jeff, I see your point  however, I described my c++ project as an application, which is actually missleading since it is a DLL developed in C++.
Sorry for not giving the full/correct info from the beginning.
The DLL is to be used by by another C++ program. Therefore, Java seems like a non-alternative at this point. Even though I personally generally prefer Java instead of C++. |

Thank you all for your help.
I think I will try to get the customer to accept the MQ Client silent installation mass deployment solution. It really seems like the best solution.
