Describe the problem you're observing

I tried to compile version 2.2.4 exactly the same as versions 2.2.x before it

sh autogen.sh
./configure
make -j$(nproc) deb-utils

In the end I get the error

RPM build errors:

At the same time, in the directory /tmp/zfs-build-root-A9VcYovo/BUILDROOT/zfs-2.2.4-1.x86_64/usr/lib/ there is python3.11, but not python3 as indicated in the error

Describe how to reproduce the problem

Build OpenZFS 2.2.4 on Debian 12 from scratch

Include any warning/errors/backtraces from the system logs

[robn]

Confirmed. Quick fix: revert 71216b9 (#16126 #16129).

(My Python skills are nonexistent, so I'm not much use on a fix).

I have the same output as above. Note also dist-packages vs site-packages.

Even Debian sid (unstable) doesn't use python 3.12. Only Debian experimental contains python 3.12.

At the moment I'm just using

./configure --disable-pyzfs

[thisisnotmyrealname]

Same issue for me on Ubuntu 22.04.04 which has python 3.10.12

[rincebrain]

I bet I even know why.

IIRC Debian does evil nonsense to some but not all of the override mechanisms for where packages go, so after 71216b9, we probably hit one of the ones where it doesn't override it, and things end up in site-packages not dist-packages. (See also).

This explains the insanity. So basically, Debian monkeypatches only distutils for this, and not relying on distutils thereby produces unexpected results.

[pcd1193182]

We just ran into this internally, and @rincebrain's analysis is correct. The proper fix here probably involves tweaking ax_python_devel.m4 to use a scheme that puts the file in the right place on debian (the 'posix_local' or maybe 'deb_system' scheme appears to work), and then to have zfs.spec.in use the $PYTHON_SITE_PKG variable to define where it expects the file to end up. That may require some more tweaking, though, because the installation process uses the --prefix flag to setup.py to tweak the install location further.

@pcd1193182: Applying the above patch as-is inside an Ubuntu Focal/20.04 build container (followed by ./autogen.sh; ./configure; make deb) changes the resulting errors from

Are you sure this is supposed to read /usr/local/? python3-pyzfs v2.2.3-1 previously used /usr/ (which is what I'd expect).

[rincebrain]

I have a simple change which makes it successfully build (though it uses site-packages not dist-packages), which I'll post when home. I personally am not incredibly concerned about sticking to dist-packages for Debian when the only way we could know that's correct from the current API surfaces is, afaict, "hardcode it", but others may disagree.

the same error on ubuntu 24.04 ,python 3.12

[aubreybailey]

Edit: looks like it's fixed in mainline 24.01 now

[PeterFalken]

Just tried to build 2.2.5 on debian bookworm and still get this error.
Had to use the workaround:
./configure --disable-pyzfs --enable-systemd
