Hey guys,

it’s my first post and I hope I put it in the right category.

1. 

Background: I’m experimenting a little bit with Ruby. I wanted to  
compile Ruby only with the only needed libs. So that the compiled Ruby  
only would have the primitive data types (including object, string etc)  
with only a few operations on these data types. No libs etc. shall be in  
the compiled Ruby.

Problem: I don’t know where to configure the source. (looked into  
mkconfig.rb, extmk.rb …) Can anyone of you tell me how to configure  
this “pure” Ruby?

1. 

Background: I had a look at the file “keywords” where the keywords like  
“while”, “do” etc. are defined. I just wanted to add another keyword  
(just for experimentation purpose). Therefore gpref is needed.

Problem: I’m using msys combined with mingw to compile Ruby. I don’t  
know how to “implement” gpref into msys. Does anyone know how to do it?

Thank you for reading this topic. Possibly someone can help me with my  
problems.
