Hi,  
“make” has a -e option in which it reads environment variables and  
uses those values for variables defined in the makefile. For e.g.  
enviroment variable CC=cc -g can be used with make -e to get a debug  
build. Is there something similar with Rake? And what is the ruby  
equivalent of CC. Should I set in my environment RUBY=ruby  
\<ruby\_options\>

Thanks in advance for any help.

Regards,  
-Manas

There is no Ruby equivalent to cc.

Hi Manas,  
You can access environment variables in Rake like this:  
ENV[‘VARIABLE\_NAME’]. And you can set the options for running ruby  
with the RUBY\_OPT environment variable
