Compiling MD5 on linux shell

[xivShin]

Hi guys,

I need to compile a MD5.cc on Linux shell but I keep getting these errors :

user@ubuntu /Desktop/Hash12$ g++ -Wno-deprecated md5.cc -o md5
In file included from md5.cc:48:
md5.hh:48:21: error: fstream.h: No such file or directory

md5.cc: At global scope:
md5.cc:140: error: variable or field ‘update’ declared void
md5.cc:140: error: ‘istream’ was not declared in this scope

Anyone have any idea what I need to do to compile successfully? Thanks alot!

Change fstream.h to fstream, and iostream.h to iostream, then prefix
all usages of istream, ostream, ifstream, cerr, and endl with std::.

The problem is that md5.cc is too old (or your compiler is too new).
