how to find ruby header file without platform dependency.

[Jun Young Kim]

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

=>
