PDK_ROOT (and other paths passed) must be absolute

[thesourcerer8]

Describe the bug When PDK_ROOT contains "../" to refer to the PDK, openlane fails. Workaround: Make sure that PDK_ROOT does not contain ../ for example in the following way: export PDK_ROOT=$(readlink -f $(pwd)/../pdk ) Due to good the workaround, this bug is not urgent.

To Reproduce Steps to reproduce the behavior: export PDK_ROOT=../pdk make user_proj_example

The resulting error:

cd openlane && make user_proj_example make[1]: Verzeichnis „/media/philipp/Daten/skywater/caravel_stdcelllib_stdcells_project/openlane“ wird betreten ############################################### [INFO]: ___ ____ ___ ____ _ ____ ____ ___ / \ | \ / ]| \ | | / || \ / ] | || o ) [ | _ || | | o || _ | / [ | O || / ]| | || |_ | || | || ] | || | | [ | | || || _ || | || [_ _/ || ||||||||||||||_____|

Expected behavior It should work normally

Desktop (please complete the following information):

• OS: Ubuntu
• Openlane Version v0.15
• open_pdks Version: [commit hash]
• skywater-pdk Version: [commit hash]

This has to do primarily with how Docker works- all paths need to be absolute. Sadly, this is not an easily fixable issue.

Please readlink -f or realpath all paths used.
