Subject: [Unison-hackers] is it normal that 'make' produces different
 results each time
Message-ID: <20180927045416.GK11082@ofb.net>

Hi,

I'm trying to compile Unison on Raspbian so that I can get the
protocol versions to match the recent version on my laptop.

I noticed that if I go into the src directory and run "make" then it
produces different results each time I run it, is that normal?
Eventually it seems to converge but I wonder why it takes more than
one invocation. (see transcript below) Also, is there a way to specify
the destination directory for when I install it?

Thanks,

Frederick
