What‘s Ruby

Ruby is the interpreted scripting language for quick and easy object-oriented programming. It has many features to process text files and to do system management tasks (as in Perl). It is simple, straight-forward, and extensible.

Features of Ruby

Simple Syntax
Normal Object-Oriented features(ex. class, method calls)
Advanced Object-Oriented features(ex. Mix-in, Singleton-method)
Operator Overloading
Exception Handling
Iterators and Closures
Garbage Collection
Dynamic Loading of Object files(on some architecture)
Highly Portable(works on many UNIX machines, and on DOS, Windows, Mac, BeOS etc.)

How to compile and install

This is what you need to do to compile and install Ruby:

  1. If ./configure does not exist or is older than configure.in,
     run autoconf to (re)generate configure.

  2. Run ./configure, which will generate config.h and Makefile.

     Some C compiler flags may be added by default depending on your
     environment.  Specify optflags=.. and warnflags=.. as necessary
     to override them.

  3. Edit defines.h if you need.  Usually this step will not be needed.

  4. Remove comment mark(#) before the module names from ext/Setup (or
     add module names if not present), if you want to link modules
     statically.

     If you don't want to compile non static extension modules
     (probably on architectures which does not allow dynamic loading),
     remove comment mark from the line "#option nodynamic" in
     ext/Setup.

  5. Run make.

  6. Optionally, run 'make test' to check whether the compiled Ruby
     interpreter works well.  If you see the message "test succeeded",
     your ruby works as it should (hopefully).

  7. Run 'make install'

     You may have to be a super user to install ruby.

If you fail to compile ruby, please send the detailed error report with the error log and machine/OS type, to help others.
