Brian and others,
It's not quite that simple. After some initial thrashing around, I
installed zmq from source, and then pyzmq--but I can't import zmq:
In [1]: import zmq
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
/home/efiring/<ipython console> in <module>()
/usr/local/lib/python2.6/dist-packages/zmq/__init__.py in <module>()
24
#-----------------------------------------------------------------------------
25
---> 26 from zmq import _zmq
27 from zmq._zmq import *
28
ImportError: libzmq.so.0: cannot open shared object file: No such file
or directory
But it is right where it should be:
efir...@manini:~/programs/py/ipython/pyzmq_git$ ll /usr/local/lib/libzmq*
-rw-r--r-- 1 root root 4736930 2010-09-03 14:35 /usr/local/lib/libzmq.a
-rwxr-xr-x 1 root root 825 2010-09-03 14:35 /usr/local/lib/libzmq.la
lrwxrwxrwx 1 root root 15 2010-09-03 14:35 /usr/local/lib/libzmq.so
-> libzmq.so.0.0.0
lrwxrwxrwx 1 root root 15 2010-09-03 14:35
/usr/local/lib/libzmq.so.0 -> libzmq.so.0.0.0
-rwxr-xr-x 1 root root 1993116 2010-09-03 14:35
/usr/local/lib/libzmq.so.0.0.0
And it looks like the extension was built OK, complete with linking:
gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall
-Wstrict-prototypes -fPIC -I/usr/local/include -I/usr/include/python2.6
-c zmq/_zmq.c -o build/temp.linux-x86_64-2.6/zmq/_zmq.o
zmq/_zmq.c:1995: warning: ‘__pyx_doc_3zmq_4_zmq_7Message___len__’
defined but not used
gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions
build/temp.linux-x86_64-2.6/zmq/_zmq.o -L/usr/local/lib -lzmq -o
build/lib.linux-x86_64-2.6/zmq/_zmq.so
I'm stumped.
