How to create zookeeper.so for newer version

[mihir6692]

Hi,
I am trying to build libzookeeper_mt.so.2.0.0 and zookeeper.so for newer version of zookeeper.

I am following README . I have been able to create files from README procedure but when i use them , it gives error like below :-

ImportError: dynamic module does not define init function (initzookeeper)

Can you point to any link which can resolve issue or give some instruction for this?

Which version of ZK are you trying to update to?

I am trying create files for 3.4.x ( currently 3.4.10) versions.

That's odd. When you run zksmokes python scripts they are going to need access to the python native libraries as well as the zookeeper c client libraries.

Notice there are two libraries here:

---

$ ls lib.linux-i686-2.6/
libzookeeper_mt.so.2* zookeeper.so*

---

initzookeeper is in ./src/contrib/zkpython/src/c/zookeeper.c from zookeeper - meaning it's the python library, not in the zk client library. (python lib uses the zk c client lib)

Are you sure that both sets of libraries are available when you run the zk smoketest python script?

A few things to check: did you recompile zkpython as well from zk contrib and make it accessible to the smoketest python scripts when executing?

I haven't regenerated those files myself in quite some time. I just tried it using the following process and it worked OK.

1. used docker to spin up an ubuntu container with 14.04 (and nothing ZK specific)
2. used git to clone zk and checked out 3.4.10 release tag.
3. compiled the java code, c client, and zkpython in zk. used "install" targets to ensure everything is in the expected location (python 2.7.6 with python-dev also installed via apt-get)
4. started the zk server so that we'd have something to talk to
5. cloned zk-smoketest. deleted the "lib*" directories from zk-smoketest
6. ran "./zk-smoketest.py --servers "localhost:2181" which executed successfully

Thanks for tip. I was not building Java code and because of that test-classes were not created in build/ folder. Also i didnt build contrib code earlier.

Here are the steps i followed :-

From zookeeper repo:-

ant

ant mvn-deploy

ant complie_jute

cd src/c/

find where ACLOCAL is installed
ACLOCAL="aclocal -I /usr/share/aclocal" autoreconf -if

./configure

sudo make install

cd ../contrib

ant

cd zkpython

this last step will create zookeeper.so and install zookeeper.so into python/dist-packages
location of zookeeper.so :- zookeeper/build/contrib/zkpython/lib.linux-x86_64-2.7/
sudo ant
