Re: [Libguestfs] python 3 bindings on libguestfs

Hi, Please find below warning which I am facing while running "make" in source code of libguestfs-1.32.4: ********************************************************************** make[2]: Entering directory `/root/rpmbuild/SOURCES/libguestfs-1.32.4/python' CC libguestfsmod_la-guestfs-py.lo In file included from guestfs-py.c:36:0: guestfs-py.h: In function 'put_handle': guestfs-py.h:56:5: warning: implicit declaration of function 'PyCObject_FromVoidPtrAndDesc' [-Wimplicit-function-declaration] PyCObject_FromVoidPtrAndDesc ((void *) g, (char *) "guestfs_h", NULL); ^ guestfs-py.h:56:5: warning: nested extern declaration of 'PyCObject_FromVoidPtrAndDesc' [-Wnested-externs] guestfs-py.h:55:3: warning: return makes pointer from integer without a cast [enabled by default] return ^ CC libguestfsmod_la-guestfs-py-byhand.lo In file included from guestfs-py-byhand.c:35:0: guestfs-py.h: In function 'put_handle': guestfs-py.h:56:5: warning: implicit declaration of function 'PyCObject_FromVoidPtrAndDesc' [-Wimplicit-function-declaration] PyCObject_FromVoidPtrAndDesc ((void *) g, (char *) "guestfs_h", NULL); ^ guestfs-py.h:56:5: warning: nested extern declaration of 'PyCObject_FromVoidPtrAndDesc' [-Wnested-externs] guestfs-py.h:55:3: warning: return makes pointer from integer without a cast [enabled by default] return ^ *********************************************************************** I hope this may create below issue: [root@euca-10-254-5-129 libguestfs-1.32.4]$ ./run python Python 3.5.1 (default, Jan 30 2018, 06:34:19) [GCC 4.8.2 20140120 (Red Hat 4.8.2-16)] on linux Type "help", "copyright", "credits" or "license" for more information.

I have tried a lot and still facing "undefined Symbol" issue while importing guestfs. But Able to enable python 3 bindings in libguestfs but it's not working as expected. I could see another user faced same issue and the same has reported in below link: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=646360 I hope libguestfs-1.32.10 also having same issue. Please help us on this.

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.
