Re: [Libguestfs] python 3 bindings on libguestfs

Hi, Finally on our RHEL7 machine we are able to bind python with libguestfs. Please find below log: checking for PYTHON... yes checking Python prefix... /opt/python/x86_64/3.6.3-1 configure: Python install dir /opt/libguestfs/x86_64/1.32.10-1.el7/lib/python3.6/site-packages checking for Python extension suffix (PEP-3149)... .cpython-36m-x86_64-linux-gnu.so also python bindings turned as YES like below: This is how we have configured the optional components for you today: Daemon .............................. no Appliance ........................... no QEMU ................................ /opt/qemu/x86_64/2.4.0/bin-wrapped/qemu-kvm guestfish and C-based virt tools .... yes FUSE filesystem ..................... no GNU gettext for i18n ................ yes virt-p2v ............................ no OCaml bindings ...................... yes OCaml-based virt tools .............. yes Perl bindings ....................... no Perl-based virt tools ............... no Python bindings ..................... yes Ruby bindings ....................... no Java bindings ....................... no Haskell bindings .................... no PHP bindings ........................ no Erlang bindings ..................... no Lua bindings ........................ no Go bindings ......................... no gobject bindings .................... no gobject introspection ............... no bash completion ..................... yes :) But next problem seems to be import is not working as expected, please find below issue: [root@euca-172-31-8-98 lib]$ python Python 3.6.3 (default, Nov 29 2017, 09:19:34) [GCC 4.8.2 20140120 (Red Hat 4.8.2-16)] on linux Type "help", "copyright", "credits" or "license" for more information.

But still the log is same like below: checking for python... /usr/bin/python2.6 checking Python version... 2.6 checking for PYTHON... no checking for PYTHON... no checking Python prefix... /usr checking for Python site-packages path... /usr/lib64/python2.6/site-packages Please find below line which we are using in our SPEC: PYTHON=/usr/bin/python2.6 ./configure --disable-appliance --disable-daemon --without-libvirt --with-qemu="qemu-kvm qemu-system-x86_64 qemu" --prefix=%{_prefix} --enable-python I have tried a lot but no luck. Could you please let me know that whether you are trying this libguestfs on any RHEL machines . if yes please provide some sample spec of libguestfs for RHEL machines.
