'Trying to complie ICU by unicode on RHEL7 system
I am trying to install ICU from git clone repo.
I run ./cnfigure and everything seems fine.
When i go to run make I get a bunch of errors.
I am new to Linux and cannot find any fixes anywhere.
it seems to be a problem with the uarrsort.ccp but that is the extent of what i know.
Here are the errors i run into when running make:
g++ ... uarrsort.cpp

Sorry I am a noob. any help will be much appreciated.
thanks :)
