Hello,
[[[
fix Ruby 1.9 deprecation warning for Config, use RbConfig
* configure.ac
replace Config with RbConfig
* build/ac-macros/swig.m4
replace Config with RbConfig
]]]
The configure script reads the Ruby major and minor version to reject
configuring swig bindings for Ruby 1.9. It does this by accessing
Config::CONFIG which is deprecated in that release.
ruby -rrbconfig -e 'print Config::CONFIG.fetch(%q(MAJOR))'
ruby -rrbconfig -e 'print Config::CONFIG.fetch(%q(MINOR))'
So instead of meaningful message we get:
checking for Ruby major version... -e:1: Use RbConfig instead of
obsolete and deprecated Config.
checking for Ruby minor version... -e:1: Use RbConfig instead of
obsolete and deprecated Config.
The same warning is triggered when trying to configure SWIG_RB_COMPILE
and SWIG_RB_LINK, although that is moot as these are useless with Ruby
1.9 anyway for now. The following works with at least Ruby 1.8:
ruby -rrbconfig -e 'print Config::RbCONFIG.fetch(%q(MAJOR))'
ruby -rrbconfig -e 'print Config::RbCONFIG.fetch(%q(MINOR))'
This was found during work on the openSUSE package. Please review,
especially concerning backwards compatibility with Ruby versions older
than 1.8.
