Fwd: [Python-Dev] libxml2 installation/binding issue

[Dan Stromberg]

Perhaps look over (or use) http://stromberg.dnsalias.org/~strombrg/cpythons/ ?

It defaults to building many versions of CPython, but can build just
one if you prefer.

It knows how to build GTK+ as well, for some newer versions of CPython.

Hello,



I am not sure if this is the correct place to post an issue/question
like this, but here goes…



I’ve successfully (?) installed Python 3.6.4 and libxml2, with the
ultimate goal of installing GTK+ 3.22.0.

However, I’m running into this error:





python3

Python 3.6.4 (default, Feb  5 2018, 13:28:04)

[GCC 4.7.2] on linux

Type "help", "copyright", "credits" or "license" for more information.

>>> import libxml2

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "/nfs/sc/disks/slx_1353/mlpriest/sl1/work_root/a0/development/sfwr/lib/python3.6/site-packages/libxml2.py",
line 1, in <module>

    import libxml2mod

ImportError: /nfs/sc/disks/slx_1353/mlpriest/sl1/work_root/a0/development/sfwr/lib/python3.6/site-packages/libxml2mod.so:
undefined symbol: _PyVerify_fd





Here are the details on the version, cflags, and ldflags.

python3 --version ;

Python 3.6.4

python3-config --cflags

-I/nfs/sc/disks/slx_1353/mlpriest/sl1/work_root/a0/development/sfwr/include/python3.6m

-I/nfs/sc/disks/slx_1353/mlpriest/sl1/work_root/a0/development/sfwr/include/python3.6m

-Wno-unused-result

-fPIC -DNDEBUG

-g

-fwrapv

python3-config –ldflags;

-L/nfs/sc/disks/slx_1353/mlpriest/sl1/work_root/a0/development/sfwr/lib/python3.6/config-3.6m-x86_64-linux-gnu

-L/nfs/sc/disks/slx_1353/mlpriest/sl1/work_root/a0/development/sfwr/lib

-lpython3.6m

-lpthread

-ldl

-lutil

-lrt

-lm

-Xlinker

-export-dynamic



Anyhelp or hint would be appreciated…







Matt
