The part I don't understand is why you want to install it in system space in the first place.

We never have. Install it somewhere you have write access to and add that to your $PATH?

Hi Ralph, Abdalla,

I understand. Because there's no separate "installation phase" it

doesn't seem possible to achieve what I was thinking.

Thanks,

Lucas

Hi Lucas,

Why not? Unless I misunderstood what you want, you could do

make INSTALL_LOCATION=${HOME}/tmp/staging/ FINAL_LOCATION=/opt/test
sudo mv ${HOME}/tmp/staging/ /opt/test
sudo chown -R epics:epics /opt/test  # Or root, or whatever

Perhaps having the staging directory under $(TOP) or /tmp makes more sense, it depends on your case, but you get the idea. Would this work for you?

Or, if you really want to use make, you can obviously use INSTALL_LOCATION for your staging area, FINAL_LOCATION for the target area and add something like

final-install:
       mkdir -p $(FINAL_LOCATION); cp -a $(INSTALL_LOCATION)/* $(FINAL_LOCATION)

to the end of your top Makefile.

Cheers,
~Ralph
