/opt/gaffer-1.4.3.0-linux-gcc11

I get this error launching gaffer

  File "/opt/gaffer-1.4.3.0-linux-gcc11/bin/__gaffer.py", line 170, in <module>
    app = loadApp( appName )

ImportError: libGLU.so.1: cannot open shared object file: No such file or directory

If I install mesa-libGLU.x86_64

I get Segmentation fault (core dumped)

Anyone else having issues ?

Thanks,

Hi Robert,

The segmentation fault is likely due to some glibc changes in the RHEL/Rocky/Alma 9.4 update causing the Jemalloc memory allocator we use to crash on startup. There's a related issue on GitHub here: https://github.com/GafferHQ/gaffer/issues/5856.

The good news is we already have a fix in place for this which will be released in Gaffer 1.4.4.0 next week. Until then you can try running with Jemalloc disabled by setting the `GAFFER_JEMALLOC=0` environment variable before running Gaffer. If Gaffer still crashes after setting `GAFFER_JEMALLOC=0` then it's likely a different issue and we'd need a stack trace to debug it further.

Cheers,

Murray

Hi Murray

Many thanks,
