# SYNOPSIS
|
||||
#
|
||||
# AX_RUBY_DEVEL([version])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# This macro checks for Ruby and tries to get the include path to
|
||||
# 'ruby.h'. It provides the $(RUBY_CPPFLAGS) and $(RUBY_LDFLAGS) output
|
||||
# variables. It also exports $(RUBY_EXTRA_LIBS) for embedding Ruby in your
|
||||
# code.
|
||||
#
|
||||
# You can search for some particular version of Ruby by passing a
|
||||
# parameter to this macro, for example "1.8.6".
