Now you have to change Makefile to match your environment. If you’re using Linux,you can probably skip this step. If not, simply uncomment the lines for your operating system and comment out all the others. For example, if you’re using Mac OS X, do the following:
open Makefile : vim Makefile
- Comment out the following lines so they look like this:
# Linux defaults: #CFLAGS=-ggdb -Wall -DLINUX -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 #CFLAGS=-O2 -Wall -fomit-frame-pointer -DLINUX -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 #LDFLAGS=-s - Uncomment these lines, like so:
# Uncomment for OS X: CC=cc CFLAGS=-O2 -Wall -fomit-frame-pointer -no-cpp-precomp LDFLAGS= XOBJS=strverscmp.o
