[SOLVED] Consistent crash on Ubuntu 22.04

I installed 19.5.435 on Ubuntu 22.04, but it is crashing constantly.
I ran `source houdini_setup_bash`, added also `/lib/x86_64-linux-gnu` to LD_LIBRARY_PATH (since I needed this on another Ubuntu machine). But none of this helped. Any ideas? It seems to segfault quite early in the process.

Unfortunately that stack trace doesn't provide any information on what exactly went wrong. Have you tried without setting LD_LIBRARY_PATH?

Thanks for the response, yes I tried all kinds of permutations of sourcing the setup script, setting env vars and not.
I realize this stack is very short and shows almost nothing. Could it be caused by missing libraries? Any way to validate this?

You could try this.

source houdini_setup
sudo apt install gdb
gdb houdini

Then, in gdb, once you get the (gdb)prompt, type run.

Once it crashes, type: thread apply all bt
Copy and paste all of the output from when you started gdb to the output of the previous command and attach it here. Hopefully it will give us a clue.

Weird, there is almost nothing in this trace. Could it be that the installed video drivers are not the right ones?

Changed the library path a bit

source houdini_setup_bash
LD_LIBRARY_PATH="/lib/x86_64-linux-gnu:/opt/hfs19.5/dsolib:/opt/hfs19.5/python/lib" LD_PRELOAD="/lib/x86_64-linux-gnu/libc_malloc_debug.so.0" /opt/hfs19.5/bin/houdinicore

And now I am getting
/opt/hfs19.5/bin/houdinicore-bin: symbol lookup error: /opt/hfs19.5/dsolib/libHoudiniUI.so: undefined symbol: _ZnwmSt11align_val_t, version Qt_5

Is this related to the gcc version that libQt* were compiled with?

Here is ldd /opt/hfs19.5/dsolib/libHoudiniUI.so

Edit: btw I also tried removing the Qt libraries and using the system ones, but then I get other missing symbols.

Turned out the nvidia driver was not being used. After configuring it, it worked.

I'm glad you figured it out. fyi, adding /lib/x86_64-linux-gnu/libc_malloc_debug.so.0 to your LD_PRELOAD is no longer needed as of 19.0.594 and will greatly reduce performance.

Oh cool thanks. Is a vendored libc being used?

No, we fixed the underlying compatibility issue with glibc 2.34+.

You could try this in a Terminal window:

cd /opt/hfs19.5 # or wherever you installed houdini
source houdini_setup
houdini -foreground

Do you get the same OpenCL errors as OP in the terminal?

I able to fix by installing amd graphics drivers from the following link https://support.zivid.com/en/latest/getting-started/software-installation/gpu/install-opencl-drivers-ubuntu.html [support.zivid.com]
