I'm sorry I didn't see this sooner. Probably if this were filed under support requests or bugs I might have gotten a notification. Let's move discussion there if you are still interested.

Yes, probably the debugger is not finding the bulk of the code library and the install is supposed to make sure it gets this right. In the bashdb script look for variable _Dbg_libdir and see what directory that points to and make sure that is there.

Hi guys,

Thank you for making your work available.

I have tried using bashdb by following your example at:
http://bashdb.sourceforge.net/bashdb.html#Summary
1.1 A Sample BASH Debugger Session

Did not succeed.

Originally installed bashdb via opensuse YAST, then also the lastest version from your sources.
Same behaviour for both, both were the same version.

psaf@saffrons:~> cat /etc/SuSE-release
openSUSE 12.2 (i586)
VERSION = 12.2
CODENAME = Mantis

================================================================================
Bug desc ( session transcript below in next section ).

1)
After invoking the debugger with the script to debug
bashdb /home/psaf/bin/fact.sh
I presume that the debugger started debugging its main script itself /usr/local/bin/bashdb
and not the "fact.sh" script.

2)
After issuing "-" command, I get an error message
** Undefined command "-". Try "help".

3)
Issuing "step" takes me to the end of the script directly.

4)
Tried to debug this simple script:
#!/bin/bash
Str=hello
echo $Str
Analogous behaviour observed.

5)
Apart from the debugger not doing what I expected,
I have found out that when calling it with "-L" option
and providing trailing "/" in the directory name,
I got an error "command not found" on line 86-89
as "print" is not a bash command nor present on my system.
In the section above, "echo" is used instead.

74
75  # All _Dbg_libdir setting done above. Have we succeeded? 
76  if [[ ! -d $_Dbg_libdir ]] ; then 
77    echo "${_Dbg_pname}: Can't read debugger library directory '${_Dbg_libdir}'." >&2
78    echo "${_Dbg_pname}: Perhaps bashdb is installed wrong (if its installed)." >&2
79    echo "${_Dbg_pname}: Try running bashdb using -L (with a different directory)." >&2
80    echo "${_Dbg_pname}: Run bashdb --help for a list and explanation of options." >&2
81    exit 1
82  fi
83
84  typeset _Dbg_main="$_Dbg_libdir/dbg-main.sh"
85  if [[ ! -r $_Dbg_main ]] ; then 
86    print "${_Dbg_pname}: Can't read debugger library file '${_Dbg_main}'." >&2
87    print "${_Dbg_pname}: Perhaps bashdb is installed wrong (if its installed)." >&2
88    print "${_Dbg_pname}: Try running bashdb using -L (with a different directory)." >&2
89    print "${_Dbg_pname}: Run bashdb --help for a list and explanation of options." >&2
90    exit 1
91  fi
