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

Features of Ruby

• Simple Syntax

• Normal Object-oriented Features (e.g. class, method calls)

• Advanced Object-oriented Features (e.g. mix-in,singleton-method)

• Operator Overloading

• Exception Handling

• Iterators and Closures

• Garbage Collection

• Dynamic Loading of Object Files (onsome architectures)

• Highly Portable (works on many Unix-like/POSIX compatible platforms as wellas Windows, macOS, Haiku, etc.) cf. github.com/ruby/ruby/blob/trunk/doc/contributing.rdoc#platform-maintainers

How to compile and install

Md Readme

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

1. If you want to use Microsoft Visual C++ to compile Ruby, read win32/README.win32 instead of this document.

2. If ./configure does not exist or is older thanconfigure.ac, run autoconf to (re)generateconfigure.

3. Run ./configure, which will generate config.h andMakefile.

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

4. Edit defines.h if you need. Usually this step will not beneeded.

5. Remove comment mark(#) before the module names fromext/Setup (or add module names if not present), if you want tolink modules statically.

   If you don't want to compile non static extension modules (probably onarchitectures which do not allow dynamic loading), remove comment mark fromthe line '#option nodynamic' in ext/Setup.

   Usually this step will not be needed.

6. Run make.

   • On Mac, set RUBY_CODESIGN environment variable with a signing identity. Ituses the identity to sign ruby binary. See also codesign(1).

7. Optionally, run 'make check' to check whether thecompiled Ruby interpreter works well. If you see the message 'checksucceeded', your Ruby works as it should (hopefully).

8. Optionally, run make update-gems and makeextract-gems.

   If you want to install bundled gems, run make update-gems andmake extract-gems before running make install.

9. Run 'make install'.

   This command will create the following directories and install files intothem.

   • ${DESTDIR}${prefix}/bin

   • ${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}

   • ${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}

   • ${DESTDIR}${prefix}/lib

   • ${DESTDIR}${prefix}/lib/ruby

   • ${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}

   • ${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}

   • ${DESTDIR}${prefix}/lib/ruby/site_ruby

   • ${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}

   • ${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}

   • ${DESTDIR}${prefix}/lib/ruby/vendor_ruby

   • ${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}

   • ${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}

   • ${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}

   • ${DESTDIR}${prefix}/share/man/man1

   • ${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system

   If Ruby's API version is 'x.y.z', the${MAJOR} is 'x', the ${MINOR} is'y', and the ${TEENY} is'z'.

   NOTE: teeny of the API version may be different from oneof Ruby's program version

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

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

Some extension libraries may not get compiled because of lack of necessaryexternal libraries and/or headers, then you will need to run'make distclean-ext' to remove old configuration afterinstalling them in such case.
