Hi, I'm trying to install Houdini through the launcher but it's failing. The launcher works but when I try to install Houdini I get an error message that says 'Worker process terminated unexpectedly. Exit code 127.' That's all I have sadly. Any suggestions? I'm on Gentoo but with fairly common setup ( systemd with KDE ).

With the help of strace I figured out it was a problem with polkit ( pkexec to be exact ). Now I have the Houdini installed but it doesn't run. There are two problems.

First, when running houdini I'm getting
/opt/sidefx/Houdini19.5.303/bin/../dsolib/libHoudiniOPZ.so: undefined symbol: _ZN11x175973926021theHasDeterminedTaintE
This one I have no idea how to approach.

Second, Labs package failed to install with error
'Checksum did not match', am I missing some kind of dependency? Hard to tell.

Again, any suggestions are appreciated.

It's not perfect but I managed to make it work. I'm going to leave some info below in case someone needs it.

First, both issues I mentioned in the previous post were solved by installing latest daily build.

Second, I had OpenCL provided by ROCm ( https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime [github.com] ) and Houdini was just crashing on startup with it, not sure exactly why. I tried using mesa for OpenCL but it reports OpenCL 1.1 only ( ROCm was giving me 2.x ). At least Houdini starts now.

I read somewhere that you can fake OpenCL 1.2 support by defining:
CLOVER_PLATFORM_VERSION_OVERRIDE=1.2
CLOVER_DEVICE_VERSION_OVERRIDE=1.2
CLOVER_DEVICE_CLC_VERSION_OVERRIDE=1.2

Depending on the hardware you have and the programs you run it may work. Use at your own risk.

Hi!
I'm having this exact same issue when trying to install inside a distrobox container.
I'm getting the "Worker process terminated unexpectedly. Exit code 127". can you explain what you did to fix it?

I'm running the following commands:
> distrobox create houdini
> distrobox enter

//inside the box
> sudo dnf group install base-graphical core fonts multimedia
> sudo dnf install kate strace
// this is the installer form the website
// I let it install to where it wants
> ~/Downloads/_Installs/install_houdini_launcher.sh 
> /opt/sidefx/launcher/bin/houdini_launcher
I'm on Fedora 41 Kinoite (Atomic distro, KDE)

Any help would be apreciated


EDIT:
When I try to install the non launcher version, it finishes fine and i can launch the editor.
However it crashes instantly with the following crash log:

When I create the distrobox with ``--nvidia`` and install using the non-launcher installer.
It does start up but crashed when I try to open the add node dropdown and searching around.
