Hi
I seem to be having a little trouble with libxenstat, and was wondering
if the xenstat guys might be able to help.
I've pulled the xen-unstable.hg tree and done a somewhat clean install
(ie, post-make uninstall, as well as deleting the relevant libxenstat
libraries).
Next, I entered the tools/xenstat/libxenstat directory and modified the
Makefile so that the shared libraries would be installed. I've included
my Makefile below.
I ran:
make
make install
make python-bindings
make install-python-bindings
Next, I started a python session and entered:
import xenstat
and got the following output.
Python 2.3.5 (#2, Sep 4 2005, 22:01:42)
[GCC 3.3.5 (Debian 1:3.3.5-13)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
import xenstat
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/local/lib/python2.3/site-packages/xenstat.py", line 5, in ?
import _xenstat
ImportError: /usr/local/lib/python2.3/site-packages/_xenstat.so: undefined
symbol: xenstat_init
Any thoughts?
Thanks!
