After the latest upgrade to debian 13 (kernel version 41), my old paraview 4.4 binaries, which used to work seamlessly for several years, - failed with the message
symbol lookup error: /lib/x86_64-linux-gnu/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var
WOrkarounds like those offered in https://github.com/helloSystem/LinuxRuntime/issues/11 don’t work. The error remains.
What is it all about ? Can it be eliminated anyhow ?
You’re using binaries from ~10 years ago in an operating system that is 5 days old. I’m not surprised that something broke. Is there a reason you can’t update ParaView?
FWIW, if I understand the issue correctly, Debian 13 is loading a fontconfig that expects a newer FreeType symbol (FT_Done_MM_Var), but ParaView ends up loading an older fontconfig that doesn’t have it – probably because ParaView 4.4 shipped its own fontconfig lbrary. You could probably do some LD_LIBRARY_PATH (or related) magic to hack a fix. But honestly probably fastest to just update ParaView.
