Found the error :-) - And all good now

On my machine I uses a local klayout build and have set LD_LIBRARY_PATH 

klayout is /home/jakobsen/opentools/klayout/bin-release/klayout
jakobsen@t14:~$ echo $LD_LIBRARY_PATH 
:/home/jakobsen/opentools/klayout/bin-release
jakobsen@t14:~$ klayout -v
KLayout 0.29.0
jakobsen@t14:~$

In my nix environment - the LIB_LIBRARY_PATH is still there and klayout misses out on libgit2.so.... 

akobsen@t14:~$ cd opentools/openlane2/

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!

jorgenkraghjakobsen commented 6 days ago

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
