Python: Namespace Aravis not available

cjg · July 13, 2023, 5:45pm

Hello, my apologies in advance for some silly questions.

I have the same issue expressed in this Github issue but the solutions provided there did not resolve my problem.

>>> import gi
>>> gi.require_version ('Aravis', '0.8')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/gi/__init__.py", line 129, in require_version
    raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace Aravis not available

I have installed Aravis on my Ubuntu machine using meson as per the guide here. This was successful in some way, verified by my ability to use the commands arv-viewer and arv-tool-0.8 as expected. It is possible that this installation was not done correctly, as the aravis files are located in my home directory /home/user/aravis/aravis-0.8.27 and I do not see anything aravis related in /usr or /usr/local as the aforementioned Github discussion suggests. I attempted to set the environment variables as I believe they were instructed:

echo $GI_TYPELIB_PATH
/home/user/aravis/aravis-0.8.2

echo $LD_LIBRARY_PATH
/usr/local/lib:/home/user/aravis/arvis-0.8.27

I appreciate any help!

Hi,

GI_TYPELIB_PATH must point to the install location of Aravis-0.8.typelib.

Did you run ninja install ?

cjg · July 14, 2023, 2:35pm

Thank you for the reply.

Did you run ninja install ?

Yes, and I just double checked these install steps:

> meson setup build
Directory already configured.
> cd build
> ninja
ninja: no work to do.
> ninja install
...

And as before, I can use commands like arv-tool:

> arv-tool-0.8 --help
Usage:
  arv-tool-0.8 [OPTION?]  command <parameters>
...

And I can access the viewer tool fine.

GI_TYPELIB_PATH must point to the install location of Aravis-0.8.typelib .

Where should this typelib file normally be? I am unable to find it inside the aravis-0.8.27 directory or anywhere else, even after retrying the above installation steps.

Try meson configure -Dintrospection=enabled. You are probably missing the gobject-introspection package on your system.

cjg · July 17, 2023, 1:46pm

sudo apt-get install -y gobject-introspection resulted in gobject-introspection is already the newest version (1.64.1-1~ubuntu20.04.1)

Ran meson configure -Dintrospection=enabled in the build directory and seemingly encountered no issue. Reinstalled with ninja and there has been no change in my issue.

I have found a solution to my problem.

meson configure -Dpython.install_env=system before ninja to do a system python install.

Set GI_TYPELIB_PATH=/usr/local/lib/aarch64-linux-gnu/girepository-1.0/:/usr/lib/aarch64-linux-gnu/girepository-1.0/
