Subject Proton Python install shenanigans
Date Sun, 30 Nov 2014 16:31:20 GMT
  Hey all,
I've been tearing my hair out a bit trying to figure why I can't see the 
relevant Python modules.

I build Proton on a clean Linux Mint 17 system (which is based on Ubuntu 
14.04)

make all builds successfully and sudo make install installs the following:

fadams@zappa /usr/local/lib/proton/bindings/python $ ls -al
total 2120
drwxr-xr-x 2 root root    4096 Nov 30 12:28 .
drwxr-xr-x 5 root root    4096 Nov 30 12:20 ..
-rw-r--r-- 1 root root   89278 Nov 30 11:29 cproton.py
-rw-r--r-- 1 root root  103293 Nov 30 12:28 cproton.pyc
-rw-r--r-- 1 root root  103293 Nov 30 12:28 cproton.pyo
-rw-r--r-- 1 root root 1445471 Nov 30 12:20 _cproton.so
-rw-r--r-- 1 root root  109162 Nov 30 11:20 __init__.py
-rw-r--r-- 1 root root  151464 Nov 30 12:28 __init__.pyc
-rw-r--r-- 1 root root  151257 Nov 30 12:28 __init__.pyo


I set PYTHONPATH=/usr/local/lib/proton/bindings/python

but when I try
./msgr-recv.py

I get

Traceback (most recent call last):
   File "./msgr-recv.py", line 23, in <module>
     from proton import *
ImportError: No module named proton


Now I'm thinking that make install hasn't pulled all of the necessary 
files into /usr/local/lib/proton/bindings/python the reason I'm thinking 
that is when I tried running
source config.sh

I noticed that the PYTHONPATH it created looked like

PYTHONPATH=/home/fadams/qpid/git/qpid-proton/tests/python:/home/fadams/qpid/git/qpid-proton/proton-c/bindings/python:/home/fadams/qpid/git/qpid-proton/build/proton-c/bindings/python

and this *does* appear to work, the significant bit seems to be the 
/home/fadams/qpid/git/qpid-proton/proton-c/bindings/python bit, because 
when I tried:

PYTHONPATH=/home/fadams/qpid/git/qpid-proton/proton-c/bindings/python:/usr/local/lib/proton/bindings/python

that worked too.

So I'm thinking that the directory proton and its contents in 
qpid-proton/proton-c/bindings/python need to be copied to

/usr/local/lib/proton/bindings/python

as part of the make install process too.


Does that seem about right?

Cheers,
Frase
