Did fresh install of nix on a linux ubuntu 22.04 - cloned the openlane2 repo - opened a nix-shell in that repo and ran openlane --smoke_test

I don't know how you're setting LD_LIBRARY_PATH, but you could set it as follows:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/jakobsen/opentools/klayout/bin-release/klayout
This will make sure the right libraries can be loaded first.
Thanks for giving OpenLane 2 a try, Jørgen!
Hi Donn That is how it all ready get set from my .bashrc file:
export PATH=$PATH:/home/jakobsen/opentools/klayout/bin-release:/home/jakobsen/.cargo/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/jakobsen/opentools/klayout/bin-release
In nix-shell I just get the my original LD_LIBRARY_PATH added again.
jakobsen@t14:~/opentools/openlane2$ nix-shell
[nix-shell:~/opentools/openlane2]$ echo $LD_LIBRARY_PATH
:/home/jakobsen/opentools/klayout/bin-release/klayout:/home/jakobsen/opentools/klayout/bin-release/klayout
I will try to see if I can find out why. Yes - Openlane2 looks very nice. I will try so run some of my design this way. /J
Sadly this appears to be inherent to Nix. You can add something like this to your rcfile:
if [ "$IN_NIX_SHELL" = "" ]; then
export LD_LIBRARY_PATH=…
