Re: [Gems-users] Parameter Configuration

Hi Mike,
    I did what you said:  set ruby0.debug-start-time "1" and set 
ruby0.debug-output-file output.txt. But it only creates an empty file.
   I also tried to set ruby0.debug-verb to high. It still does not
output anyting.
   
   When I set ruby0.debug-filter to something(i.e. n), it gave error message:
"Error: User specified set of debug components, but the RUBY_DEBUG
compile-time flag is false. Solution: Re-compile with RUBY_DEBUG set
to true. " Should I use ruby0.debug-filter? How should I use it?
