Dynamic module does not define module export function (PyInit_VBoxPython3_5m) #102

vxed · 2018-01-10T14:29:13Z

ENVIRONMENT

Operating System: Debian GNU/Linux 9.3 (stretch)
Python version: Python 3.5.3
VirtualBox version: 5.2.4r119785
VirtualBox SDK version: 5.2.4r119785
Location where VirtualBox SDK is installed: /usr/lib/virtualbox/sdk
pyvbox version: 1.2.0

SUMMARY

could not use python3.5 with pyvbox (but this is donot issue of pyvbox, am have same error with pure vboxapi)
am have not any problem with use python2.7 on same host
maybe you could help with this ?

STEPS TO REPRODUCE

import virtualbox
virtualbox.VirtualBox()

Thanks for opening this issue, I'll take a quick look at the 5.2.4 SDK.
Could you describe how you're running these commands (virtualenv, system Python?) and how you installed your SDK?

sethmlarson · 2018-01-10T14:43:37Z

It looks like it's finding VBoxPython, when you installed your SDK did you use Python 3.5 or Python 2.7? You should install it with the Python version you want to use it with.

vxed · 2018-01-10T14:58:57Z

thank you for answer

am not use virtualenv, Debian 9.3 already have python3 3.5.3 version, but system version is Python 2.7.13, am want use python3 for virtualbox management

am install virtualbox from deb package which am get from official virtualbox repository, then am download and unzip to /tmp VirtualBox sdk
cd /tmp/sdk/installer
export VBOX_INSTALL_PATH=/usr/lib/virtualbox (which contains VBoxPython.so, VBoxPython2_7.so, VBoxPython3_5m.so)
python3 vboxapisetup.py install
pip3 install pyvbox

sethmlarson · 2018-01-10T15:10:22Z

Thanks for the setup steps. I'll take a look at this later as I don't have Debian 9.3 in front of me.

vxed · 2018-01-10T15:16:31Z

am have same issue with ubuntu 16.04 (looks same but maybe different in details if needed am could install ubuntu 16.04 and open new issue)

maybe you could provide information about linux distro which already tested with python3.5+ and virtualbox ?

sethmlarson · 2018-01-10T15:20:19Z

Well I develop VirtualBox using 3.5 and 3.6 on Windows and Ubuntu so Ubuntu should work properly. I'll install a fresh environment and try it out. :)

If you could provide the exact steps you took for the Ubuntu environment as well that would be appreciated!

sethmlarson · 2018-01-10T15:22:38Z

Also: try installing pyvbox with pip3 install -U --pre pyvbox to upgrade to the beta version for 5.2.* support. I need to probably tag a non-beta version for 5.2 by now.

vxed · 2018-01-10T15:27:20Z

am have same issue with vboxapi

import vboxapi
vboxapi.VirtualBoxManager()

sethmlarson · 2018-01-10T15:34:11Z

What does this print out after you install 1.3.0b1 of pyvbox?

import virtualbox
v = virtualbox.VirtualBox()
v.find_machine('MACHINE NAME')

So it's finding your VBoxPython3_4m installation it's just erroring out when it tries to import it with this message:

dynamic module does not define init function (PyInit_VBoxPython3_4m)

sethmlarson · 2018-01-10T15:38:26Z

Can you try uninstalling your Python 2.7 install of VBoxPython and installing only 3.*?

vxed · 2018-01-10T15:38:52Z

yeap am have same issue with 3.5 at debian 9.3

sethmlarson · 2018-01-10T15:40:01Z

My guess here is that for some reason the VBoxPython3_*m.so modules don't actually define PyInit_VBoxPython3_*m() function, they may only define PyInit_VBoxPython()?

vxed · 2018-01-10T15:40:58Z

which version of ubuntu you use ? am try it right now .)

sethmlarson · 2018-01-10T15:41:05Z

Can you run nm -D /usr/lib/virtualbox/VBoxPython3_*m.so | grep PyInit on your machine and give me the output?

vxed · 2018-01-10T15:42:27Z

debian 9.3

# nm -D /usr/lib/virtualbox/VBoxPython3_*m.so | grep PyInit
0000000000012562 T PyInit_VBoxPython3_5

ubuntu 14.04

# nm -D /usr/lib/virtualbox/VBoxPython3_*m.so | grep PyInit

(nothing)

sethmlarson · 2018-01-10T15:43:38Z

So it does define it... hm... I'll have to take a look at this more later. Thanks for helping out.

vxed · 2018-01-10T15:44:09Z

debian 9.3 exception contains

m=VBoxPython3_5m x=dynamic module does not define module export function (PyInit_VBoxPython3_5m)

but in file another name of function (needed PyInit_VBoxPython3_5m but it contains PyInit_VBoxPython3_5)

#nm -D /usr/lib/virtualbox/VBoxPython3_*m.so | grep PyInit
0000000000012562 T PyInit_VBoxPython3_5

vxed · 2018-01-10T16:05:56Z

khm am try this dirty hack

# cp /usr/lib/virtualbox/VBoxPython3_5m.so /usr/lib/virtualbox/VBoxPython3_5.so

# diff sdk/bindings/xpcom/python/xpcom/vboxxpcom.py sdk/bindings/xpcom/python/xpcom/vboxxpcom.py.source

< #    _asNew = []
< #    for sCandidate in _asVBoxPythons:
< #        if sCandidate[-1:].isdigit():
< #            _asNew.append(sCandidate + sys.abiflags)
< #        else:
< #            _asNew.append(sCandidate)
< #    _asVBoxPythons = _asNew
< #    del _asNew
---
> if sys.hexversion >= 0x030200f0 and sys.abiflags:
>     _asNew = []
>     for sCandidate in _asVBoxPythons:
>         if sCandidate[-1:].isdigit():

>             _asNew.append(sCandidate)
>     _asVBoxPythons = _asNew
>     del _asNew

and it works for me in same env (debian 9.3 + python 3.5.3 + virtualbox 5.2.4r119785 and virtualbox sdk 5.2.4r119785)

sethmlarson · 2018-01-10T18:22:36Z

Hey nice catch! Looks like Virtualbox named the .so module wrong somewhere? Maybe I'll investigate being able to package all of these together so that this doesn't happen in the future.

Looks like the sys.abiflags() is being added but there's no corresponding PyInit_* function for all the different abi flags.

vxed · 2018-01-10T20:30:40Z

That's a good source. We can maybe work around this by packaging VBoxPython or emitting a better error.
