Emacs Distel error "Module is not interpreted, can't set breakpoints." after interpreting

[joe lee]

Hi, I used instructions on http://bc.tech.coop/blog/070528.html to
setup distel debugging. I kept getting error "Module is not
interpreted, can't set breakpoints." after model interpreting. Here's
the details:

========================================

Environment:

GNU Emacs 23.1.1 (x86_64-redhat-linux-gnu, GTK+ Version 2.16.5)
of 2009-08-03 on x86-4.fedora.phx.redhat.com

Erlang R13B02 (erts-5.7.3) [source] [64-bit] [smp:2:2] [rq:2]
[async-threads:0] [hipe] [kernel-poll:false]
( switching to Erlang R12 5.6.5 [source] [64-bit] also got the same error)

Linux Fedora release 11: fc11.x86_64

Distel from Repository Root: http://distel.googlecode.com/svn

========================================

Steps:

* compile with debug info

(emacs@REDACTED)>  c(test, debug_info).

========================================

* connect emacs to erlang node emacs@REDACTED ( C-c C-d n )

========================================


* distel reload erlang module  ( C-c C-d L)

after this step I can see distel in the erlang node.

* Toggle a breakpoint at current line ( C-c SPC)
 got messsage : Module is not interpreted, can't set breakpoints.

 When distel debugging work, i() should show two new process
 distel:attach_init/2,
 distel:attach_loop/1,
but now it doesn't:

~/.erlang.cookie has been set, erlang:get_cookie() returns correctly.

I tried reload and interpret the module multiple times and also
switched to erlang R12, still got the same result.

I tried to connect to a erlang node outside of emacs, emacs showed a
popup windows "Attach debugger to xyz@REDACTED instead of emacs@REDACTED" when
interpreting, but still got the same error "Module is not interpreted,
can't set breakpoints."

Does anyone know how to get information to troubleshooting this problem ?

Thanks a lot.

John
