 |
|
I installed Bleder without any error messages, but i click on the icon, but It does not open.
I tryed to open it from terminal and I got this error message:
| Code: |
antonio@tux ~ $ blender-4.1
xkbcommon: ERROR: couldn't find a Compose file for locale "C.UTF8" (mapped to "C.UTF8")

How can I solve this problem? |

The error message makes it look very much like an issue with OpenGL support on your system.
What GPU and which driver are you running? Are other 3D / OpenGL applications working?
From https://www.blender.org/download/requirements/ these are the OpenGL versions needed for Blender, by version:
| Code: |
Blender 4.x -> OpenGL 4.3
Blender 3.6 -> OpenGL 3.3
Blender 2.79 -> OpenGL 2.1
Blender 2.76 -> OpenGL 1.4
|
So it could be
- due an integrated GPU or older GPU that doesn't support OpenGL 4.3 yet,
- drivers that don't support OpenGL 4.3 yet
- your media-libs/mesa might not being built for your GPU (Gentoo's mesa uses the VIDEO_CARDS environment variable, see bottom of https://packages.gentoo.org/packages/media-libs/mesa for the settings it picks up)
You can check if the older Blender LTS releases (complete Linux builds can be downloaded from the Blender website) work.
Last but not least, Blender is moving to the Vulkan graphics API, it is enabled in early alpha builds (https://www.gamingonlinux.com/2023/10/blender-enables-vulkan-as-an-experimental-option/ - download the linked alpha build and pass --factory-startup --gpu-backend vulkan on the command line). That might not be the best option stability-wise, but if you have a capable GPU, it's an option. |

My computer does not have an dedicated video card, it is very old, it is an i5 third generation with 8GB RAM.
I used blender many times on my computer (that time I was not using gentoo, but debian), to render simple objects.
Is there a way to install blender on my computer? I just installed gentoo on my computer. |

3rd Gen i5 is Ivy Bridge. Ivy Bridge has a max OpenGL of 4.2 on mesa according to https://wiki.gentoo.org/wiki/Intel
So if Cygon's version map is true, you cannot use Blender 4.x, only 3.6. (or possibly the vulkan builds)
I would suggest emerge --deselect media-gfx/blender then emerge media-gfx/blender:3.6. Do understand that a bunch of python 3.11 must be reenabled in package.use files to get this to work. |

I will try this solution later

I installed OpenGL
| Code: |
virtual/opengl
dev-perl/OpenGL
|
And installed Intel drivers
Do I need to do something else to have Blender 3.6 working on my computer? |

You probably had Blender 3.6 installed on your Debian system.
Blender 3.6 should run on your i5 with Gentoo, too.
1) Check that your make.conf is setting VIDEO_CARDS like this:
| Code: | # /etc/portage/make.conf
# ...
VIDEO_CARDS="intel"
# ... |
2) (( Note: the OpenGL package is media-libs/mesa. It's installed automatically when you install Blender via emerge. ))
3) grknight's instructions are exactly what I'd suggest as well.
The newer versions, like Blender 4.1 (released only two months ago), probably won't run.on the old i5 without a dedicated GPU. |

As I look deeper, this is actually part of the 4.1.1 ebuild as well. It can be enabled with both the vulkan USE and the experimental USE. No need for an extra download. |

I tried to install in an older installation of gentoo, I got this error:
| Code: |
!!! The slot conflict(s) shown above involve package(s) which may need to
!!! be rebuilt in order to solve the conflict(s). However, the following
!!! package(s) cannot be rebuilt for the reason(s) shown:
(dev-python/cairocffi-1.4.0:0/0::gentoo, installed): ebuild is masked or unavailable
(dev-python/xcffib-1.2.0:0/0::gentoo, installed): ebuild is masked or unavailable
(dev-qt/qtwebengine-5.15.8_p20230112:5/5.15::gentoo, installed): ebuild is masked or unavailable
(media-video/vlc-3.0.18:0/5-9::gentoo, installed): ebuild is masked or unavailable
(media-libs/mlt-7.12.0:0/7::gentoo, installed): ebuild is masked or unavailable
It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.
For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.

We asked you to try an older version of Blender, not an older installation of gentoo.  |
