Howdy, I'm using Ruby 1.8.0 preview2 and the 'debug' module does not stop at breakpoints. OS: Solaris 2.6 & 8 (ruby built on Solaris 2.6) CC: gcc-3.2.1 Ruby: 1.8.0 preview2 with 'supplementation' Here is a sample source file and debugging session: --- source (/tmp/foo.rb) --- #!/usr/sepp/bin/ruby-1.6.8preview2 # p 1 p 2 p 3 p 4 p 5 exit 0 --- debugging session --- /usr/sepp/bin/ruby-1.8.0preview2 -r debug /tmp/foo.rb Debug.rb Emacs support available. /tmp/foo.rb:3:p 1 (rdb:1) l [-2, 7] in /tmp/foo.rb 1 2 # => 3 p 1 4 p 2 5 p 3 6 p 4 7 p 5 (rdb:1) b 5 Set breakpoint 1 at foo.rb:5 (rdb:1) c 1 2 3 4 5 As you can see the debugger failed to stop at the breakpoint I set. Any help/guidance will be greatly appreciated. Thanks, Jeff. -- Jeff Putsch Email: putsch / mxim.com Maxim Integrated Products Office: (503)547-2037 High Frequency CAD Engineering
