Hi,

I am trying to install OpenPDK (for Sky130) in my Windows 11 PC on WSL2 based Ubuntu 24.04. I am using the steps here. I am getting error while doing the process and unable to proceed. I hope someone can help me.

First, I installed Xschem, Magic and ngspice successfully. Then I started installing OpenPDK.
I ran the following commands:

1. git clone git://opencircuitdesign.com/open_pdks
This command ran OK.

2. cd open_pdks

3. ./configure --enable-sky130-pdk --prefix=/home/emma
This command also went OK.

4. make
After 45 min this command exited with ‘error2’. The log has several of the following errors:
……..
……..
fatal: early EOF
fatal: fetch-pack: invalid index-pack output
Failed to execute git cmd after 5 retries
.....
.....

Pls see the screenshot.



I contacted Stefan (Xschem) and Dr Tim (www.opencircuitdesign.com) but no solutions yet.


Dr Tim did tell me about Volare. However, I am unable to install it as well. It is giving error as below:



I have reported the matter to github locations of OpenPDK and Volare.



OpenPDK github reporting link



Volare github reporting link



Can anyone pls help in this regard? I have tried all I could. Still no solution for the past 20-25 days.



I look forward to your responses.

Thanks,
Emma.

I don't understand git at all but manage to compile point tools if the instructions are good.

Question what's making something apparently go looking for files elsewhere. Maybe an update command in the makefile (don't go thinking I have a clue, now - only an eye for suspicious error-barf).

Now in some cases I find it necessary to "sudo make" as me-as-me (not root) pukes on any permission-fail on any file in the chain.

Thanks for your reply. However sudo make (and appending sudo in front of various other commands for installing open_pdk) didnt work. I also tried by changing from https to ssh while doing make and tried by downgrading to https1.1 from 2.0. These techniques also didn't work.

Emma.
