I am running dbg from the command-line. As far as I understand the proper usage is dbg-cli, file /path/to/file.php, run, step, etc. But as soon as I type "run" it completes and I have no option whatsoever to step through the code line by line. Here is what it looks like:

[root@server dbg]# dbg-cli
DBG php debugger, version 2.15.5, Copyright 2001, 2007, Dmitri Dmitrienko, www.nusphere.com

dbg>file /home/joe/public_html/index.php
Reading symbols from /home/joe/public_html/index.php...done.

dbg>step
The program is not being run.

dbg>run

dbg>step

dbg>


Help!!

make sure that debugger module is installed. Dbg 2.15.5 should appear in phpinfo and its status should be "ENABLED = ON"

I think the debugger is enabled. From php.ini:

extension=eaccelerator.so
; extension=xcache.so
extension=memcache.so
extension=suhosin.so
extension=amf.so
extension=dbg.so

[debugger]
debugger.enabled=on
debugger.profiler_enabled=on

From phpinfo():

2006 eAccelerator, by eAccelerator
with DBG v2.15.5, (C) 2000,2007, by Dmitri Dmitrienko
with Suhosin v0.9.27, Copyright (c) 2007, by SektionEins GmbH

I moved extension=dbg.so from last to first and and my sysadmin sent a letter saying I crashed some scripts and dbg.so must go last...
Running the latest CentOS, dbg built from source.

Any other ideas?
