I am trying to build a Python application installer that is using libguestfs. I using the
instructions to create the python package posted at
https://github.com/libguestfs/libguestfs/commit/fcbfc4775fa2a440209740735...
I am getting errors in the compile when I do the "pip install”. I have attached the
output from pip. I looked at the code and I do not see anything obvious)
When I do a yum install of python-libguestds.x86_64 the python interface works correctly.
Version/Platform Information
Platform: Centos-7
libguestfs version: 1.31..6
$ uname -a
Linux localhost.localdomain 3.10.0-229.11.1.el7.x86_64 #1 SMP Thu Aug 6 01:06:18 UTC 2015

I think what is happening is that you've got an older version of
libguestfs installed than the one you're building the python bindings
for.
Because libguestfs (eg. git) contains its own python bindings, the
assumption has always been that the version of libguestfs will be
exactly the same (ie. all APIs will be present and identical).
If you build different versions, then that's no longer true, so you
see errors from "missing" APIs (ie. ones not present in your old
version of libguestfs). eg:
build/temp.linux-x86_64-2.7/guestfs-py.o
guestfs-py.c:310:26: warning: ‘struct guestfs_btrfsbalance’ declared inside
parameter list [enabled by default]
put_btrfsbalance (struct guestfs_btrfsbalance *btrfsbalance)
^
This could be fixed, but needs patching in generator/python.ml
upstream.

Richard,
Thanks for fast reply - let me remove all the yum packages and then
build/install from single version.

I would avoid using 'make install' in the libguestfs git repo.
A better plan may be to roll back the git repo to match the version of
libguestfs you have installed (from yum), eg:
git reset --hard 1.28.1
then try the pip method again.

Richard,
It is looking better, but still getting error - see attached log.
I removed all installed packages and yum installed libguestfs

Then reset my git repository to 1.28.1 and then
$ make clean
$ ./autogen.sh --disable-erlang --disable-perl --disable-lua --disable-ruby

That's pretty close to working. We remove the *_9p functions in RHEL
because they are not supportable, so if you edit guestfs-py.c by hand
to remove those bindings it may work.

Richard,
I put an #ifdef around the logic in py_guestfs_mount_9p and
py_guestfs_list_9p, I.e. Left the signatures but the functions just return
a a NULL PyObject. It now builds and installs with pip.
Thanks for all your help most appreciated.
Is there a better way to do this?, #ifdefs always seem a little hacky.

Actually I was wondering why the python-libguestfs package from RHEL
doesn't work for you. I don't use Python much myself, but is there
some benefit to using PIP?
In answer to your question, yes the #ifdefs are hacky. We need to fix
the bug I mentioned before properly.

Richard,
The Redhat yum package works for global settings. Just in the habit of
using Python virtual environments, keeps python packages separate and
easier to track which packages are required in by an application.
