Re: [Libguestfs] python 3 bindings on libguestfs

Hi, We have done on fresh instance. We have manually installed libguestfs-1.32.10. I could see below log while running ./configure: checking Python version... 3.6 checking for PYTHON... yes checking Python prefix... /opt/python/x86_64/3.6.3-1 checking for Python site-packages path... /opt/python/x86_64/3.6.3-1/lib/python3.6/site-packages checking for Python extension suffix (PEP-3149)... .cpython-36m-x86_64-linux-gnu.so checking for PyCapsule_New in -lc... no checking for PyString_AsString in -lc... no checking for ruby... ruby checking for rake... no It seems like still " checking for PyString_AsString in -lc... no". Please find below details while we run ./run python the issue is different: [root@euca-10-254-5-21 libguestfs-1.32.10]$ ./run 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. Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/var/fpwork/libguestfs/libguestfs-1.32.10/python/guestfs.py", line 73, in <module> import libguestfsmod ImportError: /var/fpwork/libguestfs/libguestfs-1.32.10/python/.libs/libguestfsmod.cpython-36m-x86_64-linux-gnu.so: undefined symbol: PyCObject_FromVoidPtrAndDesc Please let me know why this issues is coming again and again. Even google itself nothing is there to resolve the same. Please find below steps which we are using to install libguestfs: ./configure --disable-appliance --disable-daemon --without-libvirt --with-qemu="qemu-kvm qemu-system-x86_64 qemu" --prefix=/home_local/libguestfs/1.32.0/ --enable-python Please help me on this.

I think most likely you've either attached the wrong log, or it's loading libguestfsmod.so from another build of libguestfs (eg. one linked with Python 2) so it might be you still have the wrong PYTHONPATH. Suggest removing all other copies of libguestfs, or even restarting from a completely fresh install.
