 Posted: Mon Oct 07, 2024 7:38 am Post subject: Translating Debian packages to Gentoo |
 |
|
Hi All,
I have Oak-D Lite device I'd like to use on Gentoo:
https://docs.luxonis.com/hardware/products/OAK-D%20Lite
Link to dependencies:
https://raw.githubusercontent.com/luxonis/depthai-python/refs/heads/main/docs/install_dependencies.sh
I would like to write an ebuild once I get it to a working state manually but I think I might have not installed all dependencies yet.
Could use help translating those debian packages from the script above to Gentoo packages.
I've set up a python venv environment, installed depthai_viewer with pip but I'm getting an error:
(got to use python 3.12 as dependency apache-arrow is not 3.13 ready)
$ python3.12 -m depthai_viewer
[2024-10-07T07:19:00Z ERROR eframe::native::run] Exiting because of error: Wgpu(NoSuitableAdapterFound) on event Resumed
Traceback (most recent call last):
File "<frozen runpy>", line 198, in _run_module_as_main
File "<frozen runpy>", line 88, in _run_code

File "/home/erg/Oak-D_Lite/lib/python3.12/site-packages/depthai_viewer/__main__.py", line 27, in main
sys.exit(bindings.main(sys.argv, python_exe, site_packages_directory))
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
RuntimeError: WGPU error: Failed to create wgpu adapter, no suitable adapter found. -> Failed to create wgpu adapter, no suitable adapter found.
Any advice on how to approach this beyond translating packages to Gentoo ones would be super helpful. |

Let's see. As far as I can tell from https://packages.debian.org:
| Code: | python3
python3-dev |
Those are dev-lang/python on Gentoo, which you will have because of Portage 
| Code: | python3-pip
udev
cmake
git
python3-numpy
pkg-config
libjpeg-dev
libpng-dev
libtiff-dev
libsm6
libxext6
qtchooser |
Those are, in order, dev-python/pip, sys-apps/systemd-utils[udev] (i. e. installed with the udev USE flag set) on Gentoo with OpenRC or sys-apps/systemd on Gentoo with systemd, dev-build/cmake, dev-vcs/git, dev-python/numpy, dev-util/pkgconf (but ebuilds should specify virtual/pkg-config), media-libs/libjpeg-turbo, media-libs/libpng, media-libs/tiff, x11-libs/libSM, x11-libs/libXext and dev-qt/qtchooser.
That is x11-libs/gtk+:2, i. e. the slot 2 package.
| Code: | libavcodec-dev
libavformat-dev
libswscale-dev
ffmpeg |
Those are media-video/ffmpeg.
| Code: | libtbb-dev
libtbbmalloc2 |
Those are dev-cpp/tbb.
| Code: | python3-pyqt5
python3-pyqt5.qtquick |
Those are dev-python/PyQt5[declarative], i. e. installed with the declarative USE flag set.
| Code: | qtdeclarative5-dev
qml-module-qtquick2
qml-module-qtquick-layouts
qml-module-qtquick-window2 |
Those are dev-qt/qtdeclarative:5, i. e. the slot 5 package.
| Code: | qtbase5-dev
qt5-qmake
qtbase5-dev-tools |
Those are dev-qt/qtcore.
| Code: | qml-module-qtquick-controls2
qml-module-qt-labs-platform |
Those are dev-qt/qtquickcontrols2.
| Code: | libdc1394-dev
libgl1-mesa-dev |
And those are, in order, media-libs/libdc1394 and media-libs/mesa.
This thread probably belongs in "Unsupported Software".

@GDH-gentoo: Who are you, really?!? I feel so small now 
This is super helpful, thank you so much! Exactly what I needed to get me started.
This is going to be slow going due to life, I'll come back with more questions once I hit another wall. |

preserves the timestamps from the archive instead, but this is usually not

I can download file manually.
Tried unpacking it in /var/tmp/portage/dev-python/depthai-0.0.2.1/homedir/.hunter/_Base/Download/Hunter/0.23.258/062a19a/Unpacked
Didn't help. |

For fail with github.com, try this solution : disable adns USE on net-misc/curl
EDIT : I think I have solved this with a change in nsswitch.conf but I don’t remember what ... |

From a quick look, since the message is from CMake, it seems like the build is trying to download things from the internet (not good).
Such attempts will fail due to the sandbox the ebuild functions are being run in.
Usually this is a problem with tests, since there are many that require network access, but sometimes there are these "fun" things people do with build systems...
All the things required should be downloaded when fetching the sources.

@nicop: gave it a shot, no luck
@Chiitoo: I see, this seems like that road ends here then as I do not think I can convince maintainers to change their packaging.
Unless there's a way I do not see here, back to running a docker image it is. Sad. |

Have you tried a manual build first before going the ebuild route? Not a manual installation, just a manual build. This exercise should give you an idea about the way this build system works.

@GDH-gentoo: I have tried that now. It happily downloads a ton of stuff from github and luxonis website and proceeds a lot further before crashing with:
| Code: | -- Found PythonInterp: /usr/bin/python (found version "3.13")
CMake Error at tools/FindPythonLibsNew.cmake:133 (message):
Python config failure:
Traceback (most recent call last):
File "<string>", line 1, in <module>
from distutils import sysconfig as s;import sys;import struct;
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ModuleNotFoundError: No module named 'distutils' |
(I do have dev-python/distutils installed, thought this provides distutils now.)
Looks like there are a lot of bodies buried here :/ |

As Chiitoo said, build systems should not do this.
For your distutils failure, I do not see dev-python/distutils in the main tree. Is this an overlay package? |

The distutils module has been deprecated since Python 3.10, and removed fron Python 3.12. The recommended replacement for module distutils.sysconfig, which is what this code is trying to import, is the sysconfig module, so it looks like patching is going to be needed for working with recent versions of Python.
