I try to run Houdini 20.5 latest production built 370 under Rocky Linux 9.4. Sestatus is set to disabled. System Python has been upgraded to 3.11.7.

This is what I get via terminal:

$ cd /opt/hfs20.5
$ source houdini_setup
The Houdini 20.5.370 environment has been initialized.
$ houdini
/opt/hfs20.5/bin/houdini-bin: error while loading shared libraries: libXss.so.1: cannot open shared object file: No such file or directory

SideFX support said try installing libxss1. Haven't I done so? If I try sudo dnf install libxss or libxss1 (without suffix.so) the terminal states libxss1 not found.

Hope the community can help with that

If you type "dnf provides */libxss1" ... this command should tell you what package has that library file.

I also noticed that the library files you installed are for the i686 platform. You might want to install the files for the x86-64 platform instead. i686=32 bit architectures and x86_64=64 bit architectures. Since Houdini is a 64 bit application.. this might be your issue.

Thanks, I'll give this a try

dnf provides */libxss1 in fact yields "No matches found". Also tried dnf update and dnf clean-all ahead of it

The following will install the required libraries.

However as has been mentioned previously, it looks like the packages are being installed for i686 and not x86_64.

The following will install the required libraries.

sudo dnf install alsa-lib compat-openssl11 dbus-libs expat fontconfig glibc libatomic libevent libglvnd-glx libglvnd-opengl libICE libSM libX11 libX11-xcb libxcb libXcomposite libXcursor libXdamage libXext libXfixes libXi libxkbcommon libxkbcommon-x11 libXrandr libXrender libXScrnSaver libXt libXtst libzstd nspr nss nss-util openldap pciutils-libs tbb xcb-util xcb-util-image xcb-util-keysyms xcb-util-renderutil xcb-util-wm zlib 

However as has been mentioned previously, it looks like the packages are being installed for i686 and not x86_64.

Thank you very much! I'll try this next.

Almost everything was there, and it's definitely x86_64 according to terminal like : Package libxcb-1.13.1-9.el9.x86_64 is already installed, etc. However,
compat-openssl11 x86_64 1:1.1.1k-4.el9_0 appstream 1.5 M
libXScrnSaver x86_64 1.2.3-10.el9 appstream 24 k

have been installed - also for x86_64. It's working now. Thank you very much!
