Hi,
I have an IOC directory which is revision controlled using Git. It
contains iocBoot directories for multiple IOC instances. An automatic
deployment system runs something like this (simplified):

git pull
make

This generally works fine. But whenever we are retiring an IOC instance
which means we are removing the corresponding sub-directory in
$(TOP)/iocBoot from the Git repo. Now running the commands above fails.
Turns out this is because the first make run generated
iocBoot/ioctest2/envPaths which is left behind when running "git pull"
(Git only manages files, it automatically deletes empty directories but
it can't delete my iocBoot directory since it still contains an
auto-generated file).

I'm wondering if it would be possible/safe to use a Make rule that only
considers sub-directories of iocBoot that actually contain a Makefile.
Any thoughts?

Thanks,

Martin

P.S.: Steps to reproduce:

mkdir test
cd test/
git init
makeBaseApp -t ioc test
makeBaseApp -t ioc -i -a linux-x86_64 -p test test
git add -A
git commit -m "IOC with one boot dir"
makeBaseApp -t ioc -i -a linux-x86_64 -p test2 test2
git add -A
git commit -m "add 2nd IOC boot dir"
make -s
git revert HEAD
make
