We don't have any package named g-ir-scanner.

If you did download the binary/tried to build the package, give some additional information about the package

That's the part of gobject-introspection

I don't know why.. but I don't get that error...

[leap0x7b]

Even when reinstalling gobject-introspection, it still doesn't work

[Yisus7u7]

I can confirm the same error

Now I understand why pygtk doesn't work.

I saw https://github.com/termux/termux-packages/actions/runs/1310039030 and noticed that the shared object for the module giscanner._giscanner is named

/data/data/com.termux/files/usr/lib/gobject-introspection/giscanner/_giscanner.cpython-38-x86_64-linux-gnu.so

which in fact targets python3.10 + aarch64.

So I wonder if the main issue can be worked around by renaming this file to

/data/data/com.termux/files/usr/lib/gobject-introspection/giscanner/_giscanner.cpython-310.so

or any other appropriate name with which the Python interpreter in use can find the file.

[ghost]

x86_64 shouldn't have effect on loading of shared object. At least issues didn't happened in context of Python 3.8 / 3.9 and package borgbackup.

Most likely package just needs to be rebuilt.

[xtkoba]

The latest action for borgbackup (https://github.com/termux/termux-packages/actions/runs/1310038539) has shared objects named e.g.

chunker.cpython-310-x86_64-linux-gnu.so

thus the x86_64-linux-gnu part should be irrelevant. But it is odd to me that the so file built for python3.10 is annotated as cpython-38 and not cpython-310.

Anyway, by using the strace command it should be made clear whether the python interpreter is actually able to find the so file.

[xtkoba]

Ah, I cannot tell if it is actually built for python3.10. It does not seem to be linked against libpython3.10.so.1.0 (or any other shared library for different Python versions):

$ readelf -a _giscanner.cpython-38-x86_64-linux-gnu.so | grep NEEDED

This issue/PR has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

[xtkoba]

Note that when a Python extension does not have libpython* as DT_NEEDED, then it may be affected by android/ndk#201.

[xtkoba]

Nope, it may not work. borgbackup seems to work because the full name (e.g. chunker.cpython-310-x86_64-linux-gnu.so) is specified in loading scripts.

[xtkoba]

Renamed to giscanner/_giscanner.cpython-310.so. It should work.
