 Posted: Tue Jun 04, 2024 2:58 pm Post subject: profile update, libffado, python update |
 |
|
I updated my profile which a with a custom profile:
| Code: |
gentoo:default/linux/amd64/23.0/no-multilib/systemd
gentoo:targets/desktop/gnome
|
I get to the last step:
| Code: |
emerge --ask --emptytree @world
|
| Code: |
go2 ~ # emerge -a --emptytree @world
* IMPORTANT: 3 news items need reading for repository 'gentoo'.
* Use eselect news read to view new items.
These are the packages that would be merged, in order:
Calculating dependencies... done!
Dependency resolution took 2.83 s (backtrack: 0/20).
!!! The ebuild selected to satisfy "media-libs/libffado[abi_x86_32(-)?,abi_x86_64(-)?,abi_x86_x32(-)?,abi_mips_n32(-)?,abi_mips_n64(-)?,abi_mips_o32(-)?,abi_s390_32(-)?,abi_s390_64(-)?]" has unmet requirements.
- media-libs/libffado-2.4.8::gentoo USE="qt5 -debug -test-programs" PYTHON_SINGLE_TARGET="-python3_10 -python3_11"
The following REQUIRED_USE flag constraints are unsatisfied:
exactly-one-of ( python_single_target_python3_10 python_single_target_python3_11 )
(dependency required by "media-video/pipewire-1.0.7::gentoo" [ebuild])
(dependency required by "sys-apps/xdg-desktop-portal-1.18.4::gentoo" [ebuild])
(dependency required by "sys-apps/flatpak-1.14.8::gentoo" [ebuild])
(dependency required by "@selected" [set])
(dependency required by "@world" [argument])
|
Next I add this to package.use:
| Code: |
>=media-libs/libffado-2.4.8 python_single_target_python3_11
|
reissue:
| Code: |
go2 ~ # emerge -a --emptytree @world
|
and get this:

The following USE changes are necessary to proceed:

Would you like to add these changes to your config files? [Yes/No]

Since default python just changed to version 12 I am leary adding these changes to package.use.
How to proceed?
Thanks |

File a bug for libffado. If you're lucky, it'll get resolved quickly and you won't need to deal with all those package.use entries.
If you can't wait, deffer the update or enable python 3.11 explicitly.
And of course you can put those package.use entries into a temporary file which you can easily delete later when you don't need it, if your package.use is a direcotry. If it isn't, rename the file, create the directory and put the file back in, along with the temporary one.
Best Regards,
Georgi |

Thanks Georgi. I was hoping for a neater solution.

Well then I recommend going the package.use route. Setting python targets to include python 3.11 globally will result in more rebuilds when you remove it. Plus it's easier to remove a bunch of package.use entries altogether by deleting the file that contains them :)
I tried to transfer the fix from the linked GitHub issue in the bug but it's too much python for me to chew at once.
Best Regrads,
Georgi |

I've hit this one too. For now, I'll disable USE=ieee1394, which is what brung libffado into my system.
(ieee1394 is Firewire support, needed for my old Sony camcorder, but as I'm not doing anything with it at the moment I can wait for a fix.)

In my case, ieee1394 DV capture is one of the primary functions I require, so removing it is not an option.
However, it seems like only alsa-utils depends on libffado. (Why?)
It seems that adding -ieee1394 to alsa-utils in package.use is a simpler alternative in the meantime.
Has anyone contacted the libffado team about this? |

With this patch applied, at least it compiles with Python 3.12. I have not yet tested whether it works, but based on what changes are, the driver part should not stop working.
Basically, we get rid of the imp module (and use importlib), and use proper escape sequences.

Hello and welcome to the forums!
Have you considered filing a bug or attaching this patch to an existing bug about libffado?

Yes, I attached the patch to that bug just a few minutes later. |
