Hello all, could any one help me with this error while installing openlane rc6. Following error appears while running "make pdk"

Hello @ArunAshok, are you running

make pdk

inside the docker, and when was the last time you cloned the pdk (updated

pdks/skywater-pdk

)? Probably the error will be gone if you delete

pdks/skywater-pdk

and re-ran

make pdk

outside the docker.

No, I am not running it inside docker. I had first rc1 installed. Then i deleted the existing skywater and followed insructions under rc6 version. make openlane works fine, it is only under make pdk error is coming

@ArunAshok: Perhaps, check the permissions? So what happens at this stage is updating the submodules under

pdks/skywater-pdk

and then running skywater's

make timing

which internally fetches the

third_party/make-env

submodule. So either try installing in a different directory or alternatively you can try out this step manually to get a more verbose error message: https://github.com/efabless/openlane/blob/master/doc/Manual_PDK_installation.md#setting-up-the-pdk-skywater-pdk and then instead of running open_pdks manually you would run the following back in the openlane project root:

make open_pdks
make build-pdk

ok, I will first try a fresh installation first (already on it).

@ArunAshok: It seems that the make timing target in the skywater pdk doesn't support rerunning on the same directory. I'll try force deleting that directory and checking it out before running make timing

I ran into this too. I'm sorry I didn't see the thread sooner but I'm glad you got it sorted in the end
