# - Find Ruby # This module finds if Ruby is installed and determines where the include files # and libraries are. Ruby 1.8 and 1.9 are supported. # # The minimum required version of Ruby can be specified using the # standard syntax, e.g. FIND_PACKAGE(Ruby 1.8) # # It also determines what the name of the library is. This # code sets the following variables: # # RUBY_EXECUTABLE = full path to the ruby binary # RUBY_INCLUDE_DIRS = include dirs to be used when using the ruby library # RUBY_LIBRARY = full path to the ruby library # RUBY_VERSION = the version of ruby which was found, e.g. "1.8.7" # RUBY_FOUND = set to true if ruby ws found successfully # # RUBY_INCLUDE_PATH = same as RUBY_INCLUDE_DIRS, only provided for compatibility reasons, don't use it #============================================================================= # Copyright 2004-2009 Kitware, Inc. # Copyright 2008-2009 Alexander Neundorf # # Distributed under the OSI-approved BSD License (the "License"); # see accompanying file Copyright.txt for details. # # This software is distributed WITHOUT ANY WARRANTY; without even the # implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. # See the License for more information. #============================================================================= # (To distribute this file outside of CMake, substitute the full # License text for the above reference.) # RUBY_ARCHDIR=`$RUBY -r rbconfig -e 'printf("%s",Config::CONFIG@<:@"archdir"@:>@)'` # RUBY_SITEARCHDIR=`$RUBY -r rbconfig -e 'printf("%s",Config::CONFIG@<:@"sitearchdir"@:>@)'` # RUBY_SITEDIR=`$RUBY -r rbconfig -e 'printf("%s",Config::CONFIG@<:@"sitelibdir"@:>@)'` # RUBY_LIBDIR=`$RUBY -r rbconfig -e 'printf("%s",Config::CONFIG@<:@"libdir"@:>@)'` # RUBY_LIBRUBYARG=`$RUBY -r rbconfig -e 'printf("%s",Config::CONFIG@<:@"LIBRUBYARG_SHARED"@:>@)'` # uncomment the following line to get debug output for this file # SET(_RUBY_DEBUG_OUTPUT TRUE) # Determine the list of possible names of the ruby executable depending # on which version of ruby is required SET(_RUBY_POSSIBLE_EXECUTABLE_NAMES ruby) # if 1.9 is required, don't look for ruby18 and ruby1.8, default to version 1.8 IF(Ruby_FIND_VERSION_MAJOR AND Ruby_FIND_VERSION_MINOR) SET(Ruby_FIND_VERSION_SHORT_NODOT "${Ruby_FIND_VERSION_MAJOR}${RUBY_FIND_VERSION_MINOR}") ELSE(Ruby_FIND_VERSION_MAJOR AND Ruby_FIND_VERSION_MINOR) SET(Ruby_FIND_VERSION_SHORT_NODOT "18") ENDIF(Ruby_FIND_VERSION_MAJOR AND Ruby_FIND_VERSION_MINOR) SET(_RUBY_POSSIBLE_EXECUTABLE_NAMES ${_RUBY_POSSIBLE_EXECUTABLE_NAMES} ruby1.9 ruby19) # if we want a version below 1.9, also look for ruby 1.8 IF("${Ruby_FIND_VERSION_SHORT_NODOT}" VERSION_LESS "19") SET(_RUBY_POSSIBLE_EXECUTABLE_NAMES ${_RUBY_POSSIBLE_EXECUTABLE_NAMES} ruby1.8 ruby18) ENDIF("${Ruby_FIND_VERSION_SHORT_NODOT}" VERSION_LESS "19") FIND_PROGRAM(RUBY_EXECUTABLE NAMES ${_RUBY_POSSIBLE_EXECUTABLE_NAMES}) IF(RUBY_EXECUTABLE AND NOT RUBY_VERSION_MAJOR) # query the ruby version EXECUTE_PROCESS(COMMAND ${RUBY_EXECUTABLE} -r rbconfig -e "print Config::CONFIG['MAJOR']" OUTPUT_VARIABLE RUBY_VERSION_MAJOR) EXECUTE_PROCESS(COMMAND ${RUBY_EXECUTABLE} -r rbconfig -e "print Config::CONFIG['MINOR']" OUTPUT_VARIABLE RUBY_VERSION_MINOR) EXECUTE_PROCESS(COMMAND ${RUBY_EXECUTABLE} -r rbconfig -e "print Config::CONFIG['TEENY']" OUTPUT_VARIABLE RUBY_VERSION_PATCH) # query the different directories EXECUTE_PROCESS(COMMAND ${RUBY_EXECUTABLE} -r rbconfig -e "print Config::CONFIG['archdir']" OUTPUT_VARIABLE RUBY_ARCH_DIR) EXECUTE_PROCESS(COMMAND ${RUBY_EXECUTABLE} -r rbconfig -e "print Config::CONFIG['arch']" OUTPUT_VARIABLE RUBY_ARCH) EXECUTE_PROCESS(COMMAND ${RUBY_EXECUTABLE} -r rbconfig -e "print Config::CONFIG['rubyhdrdir']" OUTPUT_VARIABLE RUBY_HDR_DIR) EXECUTE_PROCESS(COMMAND ${RUBY_EXECUTABLE} -r rbconfig -e "print Config::CONFIG['libdir']" OUTPUT_VARIABLE RUBY_POSSIBLE_LIB_DIR) EXECUTE_PROCESS(COMMAND ${RUBY_EXECUTABLE} -r rbconfig -e "print Config::CONFIG['rubylibdir']" OUTPUT_VARIABLE RUBY_RUBY_LIB_DIR) # site_ruby EXECUTE_PROCESS(COMMAND ${RUBY_EXECUTABLE} -r rbconfig -e "print Config::CONFIG['sitearchdir']" OUTPUT_VARIABLE RUBY_SITEARCH_DIR) EXECUTE_PROCESS(COMMAND ${RUBY_EXECUTABLE} -r rbconfig -e "print Config::CONFIG['sitelibdir']" OUTPUT_VARIABLE RUBY_SITELIB_DIR) # vendor_ruby available ?
