How to install on a machine without root privileges.

[radwasherif]

I want to install HElib and its dependencies on a remote machine on which I do not have root privileges i.e. I cannot use "sudo" to install NTL system-wide. How can I do that, including any modifications to the makefile?

apppend he path of your NTL directory to the CFLAGS, for example, CFLAGS = -g -O2 -std=c++11 -fmax-errors=2 -Ipath_to_NTL_include, also append the path of your libntl.a to LDLIBS, such as LDLIBS = -L/usr/local/lib -Lpath_to_ntl_lib $(NTL) $(GMP) -lm

Now I am getting errors such as this:

include <string> some where.
