Dear MQ Programming Gurus,
I have compiled the following Exit program and installed in the Exit directory; setup svrconn channel to include this Exit, but got an error message saying "The application DLL c:\MqExits\fexit.dll is not a valid windows image..."
I compiled this simple c program with "cl fexit.c -o fexit.dll -LD -DEFAULTLIB mqm.lib mqmvx.lib"
Here is the source code of the dll file
Your help is much appreciated.
Thanks |

Sorry, I was struggling to repost this with the source code, but the website returned wtih message "the service is tempoary unavailable..."
Now I can only post the message with out source code.
How can I post the source code?
Thanks |

Did you read and  the user exit documentation?
Did you verify you used one of the authorized compilers?
Did you verify that your linkage table was passed correctly?
Did you build the exit in 32 and 64 bits?
Finally what is the error with error number that you are getting?
Hope this helps someone with more programming experience to help you.
Have fun

Your cl command will produce an intermediate object file (.obj), not a Dynamic Link Library file.
I prefer the 2 step compile + link approach:
cl /c /MD fexit.c
link /DLL /out:fexit.dll fexit.obj mqm.lib mqmvx.lib
