ruby-build

RUBY-BUILD(1)															     RUBY-BUILD(1)

NAME

       ruby-build - compile and install Rubies

SYNOPSIS

       ruby-build [-v|--verbose] [-k|--keep] definition prefix
       ruby-build --definitions
       ruby-build --version
       ruby-build [-h|--help]
       rbenv install [-k|--keep] definition

DESCRIPTION

       ruby-build provides a simple way to compile and install different versions of Ruby on UNIX-like systems.

       ruby-build  downloads,  builds  and  installs the Ruby version specified in a definition into a prefix directory. Definitions can be chosen
       from the list of installed definitions or by specifying a file path for a definition.

       rbenv(1) users can also use the provided rbenv install command, which installs Rubies into the rbenv directory.

OPTIONS

       --definitions
	      List available definitions.

       -k, --keep
	      Don't delete source code after installation.

       -v, --verbose
	      Display compiler messages on standard output.

       --version
	      Show ruby-build version and exit.

       -h, --help
	      Show usage information and exit.

EXAMPLES

       Install Ruby 1.9.3 (MRI, patch level 0) to ~/rubies/mri-1.9.3

	   $ ruby-build 1.9.3-p0 ~/rubies/mri-1.9.3

       Install Ruby Enterprise Edition 1.8.7 (patch level 2011.03) for rbenv(1):

	   $ rbenv install ree-1.8.7-2011.03

       Install Ruby from a custom definition into ~/your-ruby:

	   $ rbenv install /path/to/your/own/ruby/definition ~/your-ruby

ENVIRONMENT

       CC     Sets the path to the C compiler.

       CONFIGURE_OPTS
	      Options that are passed to configure when building a Ruby.

       MAKE_OPTS
	      Options that are passed to make when building a Ruby.

       MAKEOPTS
	      Used instead of MAKE_OPTS when MAKE_OPTS is not defined.

       TMPDIR Sets the location where ruby-build stores temporary files.

       RUBY_BUILD_BUILD_PATH
	      Sets the location in which sources are downloaded and built.
