version?

Fish-Git commented 7 years ago

I have marked this issue "Invalid" and added the "Question" label until Ricardo (@hackob) responds with which version of Hyperion he is using (shown at the very beginning of the hercules log file, -or-, as displayed by the hercules 'version' command). (Why so many users fail to report which version of the product they are using when they file a problem report never ceases to amaze me. I guess they think we're all psychic mind readers?)

Thank you, Ricardo! I'm sure @herc4mac (Enrico) will very likely now be able to help you with this issue. (He's our Apple/Mac expert)

hackob commented 7 years ago

False alarm. This issue is not an issue. After reviewing this message I discovered the problem was that the directory where hercifc existed was not in the PATH variable.

HHC00136E Error in function execlp(): No such file or directory

Thanks !

Fish-Git commented 7 years ago

Thank you for finding and reporting back to us with that, Ricardo. Much appreciated.

You should know of course that such is usually why we ask people to include a complete copy of their hercules log file with their problem reports -- from beginning to end -- and not just a tiny snippet of it. ;-)

In any case I'm very happy you found it. Well done and thank you!
