#.rst: # FindRuby # -------- # # Find Ruby # # This module finds if Ruby is installed and determines where the # include files and libraries are. Ruby 1.8, 1.9, 2.0 and 2.1 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 # # Also: # # ``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}${RUBY_FIND_VERSION_MINOR}") # we can't construct that if only major version is given set(_RUBY_POSSIBLE_EXECUTABLE_NAMES ruby${Ruby_FIND_VERSION_MAJOR}.${Ruby_FIND_VERSION_MINOR} ruby${Ruby_FIND_VERSION_MAJOR}${Ruby_FIND_VERSION_MINOR} ${_RUBY_POSSIBLE_EXECUTABLE_NAMES}) else() set(Ruby_FIND_VERSION_SHORT_NODOT "18") endif() if(NOT Ruby_FIND_VERSION_EXACT) list(APPEND _RUBY_POSSIBLE_EXECUTABLE_NAMES ruby2.1 ruby21) list(APPEND _RUBY_POSSIBLE_EXECUTABLE_NAMES ruby2.0 ruby20) list(APPEND _RUBY_POSSIBLE_EXECUTABLE_NAMES ruby1.9 ruby19) # if we want a version below 1.9, also look for ruby 1.8 if("${Ruby_FIND_VERSION_SHORT_NODOT}" VERSION_LESS "19") list(APPEND _RUBY_POSSIBLE_EXECUTABLE_NAMES ruby1.8 ruby18) endif() list(REMOVE_DUPLICATES _RUBY_POSSIBLE_EXECUTABLE_NAMES) endif() find_program(RUBY_EXECUTABLE NAMES ${_RUBY_POSSIBLE_EXECUTABLE_NAMES}) if(RUBY_EXECUTABLE AND NOT RUBY_VERSION_MAJOR) function(_RUBY_CONFIG_VAR RBVAR OUTVAR) execute_process(COMMAND ${RUBY_EXECUTABLE} -r rbconfig -e "print RbConfig::CONFIG['${RBVAR}']" RESULT_VARIABLE _RUBY_SUCCESS OUTPUT_VARIABLE _RUBY_OUTPUT ERROR_QUIET) if(_RUBY_SUCCESS OR _RUBY_OUTPUT STREQUAL "") execute_process(COMMAND ${RUBY_EXECUTABLE} -r rbconfig -e "print Config::CONFIG['${RBVAR}']" RESULT_VARIABLE _RUBY_SUCCESS OUTPUT_VARIABLE _RUBY_OUTPUT ERROR_QUIET) endif() set(${OUTVAR} "${_RUBY_OUTPUT}" PARENT_SCOPE) endfunction() # query the ruby version _RUBY_CONFIG_VAR("MAJOR" RUBY_VERSION_MAJOR) _RUBY_CONFIG_VAR("MINOR" RUBY_VERSION_MINOR) _RUBY_CONFIG_VAR("TEENY" RUBY_VERSION_PATCH) # query the different directories _RUBY_CONFIG_VAR("archdir" RUBY_ARCH_DIR) _RUBY_CONFIG_VAR("arch" RUBY_ARCH) _RUBY_CONFIG_VAR("rubyhdrdir" RUBY_HDR_DIR) _RUBY_CONFIG_VAR("rubyarchhdrdir" RUBY_ARCHHDR_DIR) _RUBY_CONFIG_VAR("libdir" RUBY_POSSIBLE_LIB_DIR) _RUBY_CONFIG_VAR("rubylibdir" RUBY_RUBY_LIB_DIR) # site_ruby _RUBY_CONFIG_VAR("sitearchdir" RUBY_SITEARCH_DIR) _RUBY_CONFIG_VAR("sitelibdir" RUBY_SITELIB_DIR) # vendor_ruby available ?
