You don't necessarily need to run configure as root, but there are
some tests, especially for daemons which start as root, which need the
additional privileges to execute. For example, in Asterisk, I've
written a test to check whether one may provide a bitfield longer than
1024 bits to the select(2) kernel call. This functionality is
necessary to see if we can practically have more than 1024 file
handles open, or if things would simply not work in that case. The
problem is that you cannot have a file handle numbered greater than
1023 by default in any process, so you have to increase the available
number of file handles in order to run that test.
I realize that is a very technical answer, but you have to understand
the purpose of the test in order to understand why it's necessary
sometimes to run as root.
In terms of the compile process, that could just as easily run as root
as the user, but you should definitely always run something with the
least privilege necessary to get the job done, and in terms of the
compile, root privileges are not necessary.
Thank you! That makes sense in the context (package) I am installing.
No doubt it does all manner of tests in the nature of things.
Your point is very well taken. Run with the least privilege necessary.
I understand why make install needs elevated privileges.
