Hi MQers,

I have a working channel message exit that I'm migrating to HP-UX11i. It runs correctly on earlier versions of HP-UX, on Solaris, and on AIX. Building it on HP-UX11i requires my use of the "aCC" compiler. The exit as specified in the channel exit is a shared library. It does a fork and exec of an executable. The executable communicates subsequently with the shared library using IPC (shared memory and semaphores). My symptom: The channel agent successfully finds and loads the shared library and starts correctly at the designated entry point. The fork call correctly returns a PID. However, the exec call - I'm using execl - appears to fail to load the executable. However, no error is returned to the caller. When I examine the running processes, the forked process' PID is not present.

If anyone has a C-based exit that is built as a shared library and that runs successfully on HP-UX11i, I'd very much appreciate it if I could see your build logic. If you'd be so kind, please include it in an email to the following email address: doug.pierson@state.ma.us. A shell script or a make file would be gladly accepted, as would your invocation of the compiler/linker embedded right in the email.

Thanks in advance for your help,
Doug Pierson
