 Posted: Thu Jun 27, 2024 12:58 pm Post subject: [Solved] Can't install KiCAD because of some Python problem |
 |
|
Hi folks
I'm trying to set up KiCAD on a Gentoo system I just installed. By `emerge sci-electronics/kicad` fails with an error message:
| Code: |
The following REQUIRED_USE flag constraints are unsatisfied: exactly-on-of ( python_single_target_python3_10 python_single_target_python3_10 )
|
There's some discussion of similar topics elsewhere on this forum, but I didn't understand it. FWIW `emerge --info` shows
PYTHON_SINGLE_TARGET="python3_12" and PYTHON_TARGETS="python3_12"
I'm afraid I don't know what any of this means. Can anybody tell me what I need to do to proceed?
BR, Lars.

I would suggest to allow the testing ebuild of sci-electronics/kicad by placing it in /etc/portage/package.accept_keywords (which indirectly requires dev-python/wxpython there too)
This supports python 3.12 and will be less of a headache than trying to use a stable which is python 3.11 or less.
On the other hand, if version 8 is undesirable for a different technical reason, then the only choice is to enable the python3_11 single target and disable the python3_12 single target in package.use. This will then cascade down the python chain, often quite deep. |

OK, thanks. I have started installing it. Looks like it could take a while.
KiCAD has a dependency on WxWidgets, which I kind-of understand. But do you know, or does anybody know, why WxWidgets had a dependency on GStreamer? KiCAD is not (so far as I know) known for its media capabilities. I can't see why it would need GStreamer, even indirectly.
GStreamer is one of the things I usually avoid; not for any good reason, but because I assume that anything so closely associated with Gnome must be bad  It's a pretty substantial thing to have to compile from source, if you don't need it.
BR, Lars. |

From the ebuild:
| Code: |
# wxPython doesn't seem to be able to optionally disable features. webkit is
# optionally patched out because it's so huge, but other elements are not,
# which makes us have to require all features from wxGTK
DEPEND="
>=x11-libs/wxGTK-3.0.4-r301:${WX_GTK_VER}=[gstreamer,libnotify,opengl,sdl,tiff,webkit?,X]
....
python_prepare_all() {
if ! use webkit; then
eapply "${FILESDIR}/${PN}-4.2.0-no-webkit.patch"
fi

Perhaps you could convince upstream to add a build option for disabling gstreamer. |

To be honest, alongside the colossal size of KiCAD, the 50Mb or so of GStreamer is a drop in the ocean.
KiCAD 8 does work on my system, after twelve hours of compilation; but it's not as fast as 7.0.9, which is what I've used up until now. But isn't that always the case?
