Hi,

i have written a ruby extension, that should be the base for other  
extensions. So i have to ship some of its header files.

I use setup.rb in the main directory and extconf.rb (mkmf) in the  
extensions directory.

I came about something like:

$INSTALLFILES ||= []  
$INSTALLFILES \<\< [“types.h”, “$(RUBYARCHDIR)/$(target\_prefix)”, “lib”]

included in the extconf.rb but it doesn’t work.

I know, that i can do it with a post-install.rb script, but i hope that  
there is a better solution.

cheers
