Compiling STIDE
===============

There were binary executables for STIDE in earlier time at the official Web site
(http://www.cs.unm.edu/~immsec/software/), but I don't find them now. 

I needed to compile STIDE and found that it was not compiled on current Linux 
systems (at least, popeye). Instead, g++ complained with several errors. It is hard 
to find the fixes on the Web. So, I made this document for those who want 
to compile STIDE.

To compile the source codes, you gotta do two following simple things 
(I hope UNM guys fix them sometime.):

1. In stide_v1.1/Seq-code directory, open opt_info.h.

In line 3 and 4:

#include <string>
#include "../Utils/arrays.h"

Insert "using std::string;" between line 3 and line 4 like this 
to specity that you are using a string class in C++ STL:

#include <string>
using std::string;
#include "../Utils/arrays.h"


2. And do these. These are from http://www.xcf.berkeley.edu/~paolo/ids-res/status.txt.
