How to find ruby header file without platform dependency

Ruby
1

Hello everyone.

Now I am wondering to have a way to find a location of the ruby header
file in various platforms whenever I try to configure to compile my
sources.

in case of python, it provide the ‘python-config’ executable file to
find a location of python.h.

how about ruby?

Is there any possible way to get a location(path) of it.

thanks for all.

You can look at the Config module and, in particular, at Config::CONFIG,
which
is a hash containing a number of build-time settings.

For example (using ruby 1.9):

require ‘rbconfig’ #you don’t need this line in ruby 1.8
puts Config::CONFIG.keys.sort
