Hi list,

I've created a fresh build of Python 2.4.3 using the following configuration

$ ./configure --with-pydebug --prefix=/usr/local/debug --enable-shared
--with-fpectl --with-signal-module

in particular I used --with-pydebug.

Now when I start the interpreter some dynamically loaded modules do not see
debug-related symbols:

$ /usr/local/debug/bin/python
Python 2.4.3 (#1, May 12 2006, 05:35:54)
[GCC 4.1.0 (SUSE Linux)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
Traceback (most recent call last):
File "/etc/pythonstart", line 7, in ?
import readline
ImportError: /usr/local/debug/lib/python2.4/lib-dynload/readline.so: undefined
symbol: _Py_RefTotal
>>>

I've attached a shell session with the outputs of ldd and nm on readline.so

What did I do wrong?
My System is SuSE Linux 10.1 on Intel.

Any help would be much appreciated.

Thanks, Martin.

Try with just: ./configure --with-pydebug --prefix=/usr/local/debug

I think the problem is --enable-shared. I'm not sure what you are
doing, but you probably don't need the other options. The signal
module should always be built, I've never even seen the
--with-signal-module option.

You were right, leaving out --with-pydebug did the trick.

Thanks, Martin

Nonsense! I meant leaving out --enable-shared.
