I had the same problem running OpenERP seerver 4.3 on ubuntu server 8.04. Error message when starting openerp server was
Traceback (most recent call last): File "tinyerp-server.py", line 68, in <module> netsvc.init_logger() File "/home/miran/tinyERP-server-4.3/bin/netsvc.py", line 144, in init_logger from tools import config File "/home/miran/tinyERP-server-4.3/bin/tools/__init__.py", line 30, in <module> from convert import * File "/home/miran/tinyERP-server-4.3/bin/tools/convert.py", line 43, in <module> from lxml import etree ImportError: /usr/lib/libxml2.so.2: undefined symbol: gzopen64 After googling a bit I found out that the problem is due to libz library and I located two versions of that library and couple of links: /usr/lib/libz.so.1 /usr/lib/libz.so.1.2.3.3 (good one) /usr/local/lib/libz.so /usr/local/lib/libz.so.1 /usr/local/lib/libz.so.1.2.3 (not containing gzopen64) - which I tested with objdump -T /usr/local/lib/libz.so.1.2.3 | grep gzopen64 so I substituted the one in /usr/local/lib with the one form /usr/lib/ and everything worked... I don't actually know which package brought the faulty libz to the system... Hope this helps... take care Miran -- symbol lookup error: /usr/lib/libxml2.so.2: undefined symbol: gzopen64 https://bugs.launchpad.net/bugs/151045 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
