Hi,

I would like to compile Ruby with minimum features like Base Object,  
Number, File IO, etc. (ie., I wanted to exclude the unit test, xml, ssl,  
UI, etc)

Thanks,  
-Kuppa

Never tried it, but maybe you could just remove the contents of lib/,  
and remove all the subdirs of ext/. But none of these things go into the  
ruby executable (except extensions, and even then only if you requested  
it by playing with ext/Setup).

Thanks Joel,

Actually I wanted to build small ruby interpreter to fit into some small  
OS like DSL, feather Linux, etc.

Thanks,

When building ruby, a program called miniruby is built; it seems to be  
a full ruby interpreter with minimal libs included. At work, I use it  
as a FreeBSD sysinstall replacement (well, I wrote a sysinstall  
replacement in Ruby, and my statically linked ruby calls that from  
init). It seems to do what you need.

Thanks Guest, I think, it should work. I will try and let you know.
