This is supposed to be ‘yes’ which is why it's failing.  You'll have
to debug m4/guestfs_python.m4 and config.log to find out why that is
but something is obviously broken about your Python installation.

Hi,

Have tried python2 bindings on libguestfs-1.32.10 (fresh installation).
It seems like still the log is like below:

checking for python... python
checking Python version... 2.7
checking for PYTHON... yes
checking Python prefix... /opt/python/x86_64/2.7.11-1
checking for Python site-packages path...
/opt/python/x86_64/2.7.11-1/lib/python2.7/site-packages
checking for Python extension suffix (PEP-3149)... .so
checking for PyCapsule_New in -lc... no
checking for PyString_AsString in -lc... no

But python-guestfs is working fine without any issue on python 2.7.11.

[root at euca-10-254-20-192 libguestfs-1.32.10]$ ./run
python
>>> import guestfs
>>> g = guestfs.GuestFS(python_return_dict=True)
>>> help(guestfs)
Help on module guestfs:

NAME
    guestfs - Python bindings for libguestfs

FILE
    /var/fpwork/libguestfs/SOURCES/libguestfs-1.32.10/python/guestfs.py

DESCRIPTION
    import guestfs
    g = guestfs.GuestFS (python_return_dict=True)
    g.add_drive_opts ("guest.img", format="raw")
    g.launch ()
    parts = g.list_partitions ()

    The guestfs module provides a Python binding to the libguestfs API
    for examining and modifying virtual machine disk images.

    Amongst the things this is good for: making batch configuration
    changes to guests, getting disk used/free statistics (see also:
    virt-df), migrating between virtualization systems (see also:
    virt-p2v), performing partial backups, performing partial guest
    clones, cloning guests and changing registry/UUID/hostname info, and
    much else besides.

    Libguestfs uses Linux kernel and qemu code, and can access any type of
    guest filesystem that Linux and qemu can, including but not limited
    to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
    schemes, qcow, qcow2, vmdk.

    Libguestfs provides ways to enumerate guest storage (eg. partitions,
    LVs, what filesystem is in each LV, etc.).  It can also run commands
    in the context of the guest.  Also you can access filesystems over
    FUSE.

I have followed same steps which I tried with python 3 but here its working as
expected.

Can you suggest us for further.

Regards,
Abinaya

This is supposed to be ?yes? which is why it's failing.  You'll have to
debug m4/guestfs_python.m4 and config.log to find out why that is but something
