If MQBNO is not found, then you've probably got an older (9.1?) version of MQ. Looks like something to be fixed in the C code as it ought to work

[Reopening just to give a chance for the raiser to close it (default on github was to auto-close issues after a PR).]

Although you say you're using 9.4, that dspmqver says there is at at least one other installation. Which I suspect is in the default /opt/mqm path, and which is older. That would have been being picked in preference for the compilation. You might have set the 9.4 as a primary MQ installation, but that's not known to the pip install process.

This ought to be sorted with the 2.0.0b2 level I just released, so that the default path is not used if a custom path (MQ_FILE_PATH env var) is specified during the install.

I did check the rpm modules. I did see old MQ stuff around. Environment did not seem to reference it. Rather than fight with it. I de-installed everything MQ and and reinstalled MQ 9.4.0.5. ibmmq installation worked!! Thanks. Proceed with testing my scripts under ibmmq.
