That also results in a blank.

I was playing with different ways of using Docker to containerise an EPICS installation, and in one of my experiments I tried using makeBaseApp.pl and discovered this.
To be honest, I don’t think that this would be the best way of using Docker for this task, but I thought that it was worth reporting something that looked like a bit of a weakness in makeBaseApp.
I’d be happy to make a suggested fix and submit a pull request via Git if that’s ok with you?

Hi Steve,

The EPICS Base upstream repo is on LaunchPad using Bazaar, so a patch

file would be as good.

If you do a PR, the changes would be applied to the upstream repo anyway.

Thanks a lot for your help!
