[SOLVED]Issue with blender dependencies 06 September 2021, 11:50:38 My blender refuses to start. Here's the message:Quoteblender: error while loading shared libraries: libOpenEXR-3_0.so.28: cannot open shared object file: No such file or directoryI checked for the openexr package and of course it is correct, I do not have openexr-3_0 but openexr-3.1.1-1 installed. I downgraded from cache:Quotesudo pacman -U /var/cache/pacman/pkg/openexr-3.0.1-2-x86_64.pkg.tar.zstbut now libiex is not the right version(which it would be with the up-to-date version of openexr):Quoteblender: error while loading shared libraries: libIex-3_1.so.30: cannot open shared object file: No such file or directoryI tried every package version from cache and updated blender to the newest version. Nothing worked.Questions:- how is it possible, that blender does not work with any of the packages from cache(it worked a while ago, so there should be a working openexr in cache)?- any hints on how to fix that?

Re: Issue with blender dependencies Reply #1 – 06 September 2021, 15:42:13 blender is in Arch's repo and looks like they didn't rebuild it for the openexr rebuild.
Re: Issue with blender dependencies Reply #2 – 06 September 2021, 15:45:06 yes, i got it out of the arch repo. So I'd have to build it on myself then, I guess(of which I have no idea on how to )?

Re: Issue with blender dependencies Reply #4 – 06 September 2021, 15:54:21 OK. Thanks for this hint. I'll see what I can do on the build it myself part then

First check any variation of INSTALL, INSTALL.txt, INSTALL.md, README, README.md in the source archive, and if that fails, general procedure on compiling and installing GNU/Linux programs from source.

Re: [SOLVED]Issue with blender dependencies Reply #7 – 06 September 2021, 23:48:21 As my bug report got closed and I got advice to ask in the forum, here I am again...Statement of the bug report: it is no bug, as the dependencies do not list libOpenEXR-3_0.so.28but libOpenEXR-3_1.so.30 which is correct according to this https://archlinux.org/packages/extra/x86_64/openexr/googling around and learning about things I stumbled upon lddI get this output:[manoca@IT-MOB-MANOCA ~]$ ldd /usr/bin/blender | grep -i "openexr" libOpenEXR-3_1.so.30 => /usr/lib/libOpenEXR-3_1.so.30 (0x00007f45a8616000) libOpenEXR-3_0.so.28 => not foundCan someone please explain why and/or give me a hint on what to read to learn more or less easily?
Re: [SOLVED]Issue with blender dependencies Reply #8 – 07 September 2021, 00:24:47 I installed blender and I have no issue launching it, so it's possible that your Arch and/or Artix mirror is out of date
Re: [SOLVED]Issue with blender dependencies Reply #9 – 08 September 2021, 11:02:22 my mirror is out of date? I did a pacman -Syu, which should update them? Or am I wrong?btw: for whatever reason blender is now working. I removed the blender package, and reinstalled it once more(this time I rebooted the machine as well) and now it works. Same version of blender and same version of openexr. So I do not understand why that is, but I think it's a BCAKE as always.Thanks for all your hints and time
