SITES is a software by Hey’s lab at Rutgers University. Like some other softwares, you have to compile it yourself for it to be able to run on Intel Macs.
Instruction(First one is easiest, but might not produce a working binary. Later one require you to download the makefile I wrote, but it definitely works, because I tested it.):
Download the source from SITES official website. Extract the archive. From terminal, change directory to where these .c and .h files are.
use command
gcc -O2 *.c
And you will get a a.out file. Change the name of a.out to SITES or other name you want it. Chmod 755 to make it executable. Now you can run it from command line. Mac OS X is a better environment for command line programs. So even we could run Windows on Intel Mac with Boot Camp or Parallels, I would prefer to use our very best native UNIX environment on Mac OS X.
If it doesn’t work properly, then try download the attached Makefile. Put this file in the same directory as source code, and in terminal, type “make”, then you will get the SITES executable!
