@Matt Venn @Tim Edwards I'm having some issues getting my OpenLane installation to work. Certain parts of the flow seem to run fine as root, but not as a normal user. I'm not quite sure what's going on so I've compiled a list of "observations" below. I'm hoping someone might be able to identify what I'm doing wrong and help me out. Before listing them out, I saw the warnings in the documentation about making Docker available without root and followed those closely, so I'm pretty sure it's not that. I've tried uninstalling, reinstalling, etc., etc., but still no luck and now I'm out of ideas. 1. "docker run hello-world" runs fine when I'm not root. 2. When I run "make" in the OpenLane directory. I get: Version cd1748bb197f9b7af62a54507de6624e30363943 not found locally, attempting to download… [Errno 13] Permission denied: '/opt/pdk/share/pdk/volare' 'Permission denied: '/opt/pdk/share/pdk/volare'. 3. If I run sudo make, it runs just fine though. I'm able to get all the way to where I see GDS in Klayout or Magic. 4. If I run "make mount" then ./flow.tcl -design gcd I get the following error: [ERROR]: open_pdks 30656fcd54fb8ba48caf1701f5b01b89f3f0c4fc magic 038f02d2b2802251dd9a346e0c94489026003d56 The version of open_pdks used in building the PDK does not match the version OpenLane was tested on (installed: 30656fcd54fb8ba48caf1701f5b01b89f3f0c4fc, tested: cd1748bb197f9b7af62a54507de6624e30363943) This may introduce some issues. You may want to re-install the PDK by invoking

make pdk

. The version of magic used in building the PDK does not match the version OpenLane was tested on (installed: 038f02d2b2802251dd9a346e0c94489026003d56, tested: 0afe4d87d4aacfbbb2659129a1858a22d216a920) This may introduce some issues. You may want to re-install the PDK by invoking

make pdk

. [ERROR]: Please update your environment. OpenLane will now quit. 5. If I run the above root I don't get that error. 6. I noticed that I have PDK's installed at both /usr/local/share/pdk as well as /opt/pdk/share/pdk. I'm not sure why and I'm wondering if this might have something to do with the different version errors? 7. I tried a fresh install of open_pdk from the OCD website this morning. That didn't seem to fix it.

Have you set your

PDK_ROOT

before installing? Looks like it may be trying to use a default location which may be different in docker. If you set

PDK_ROOT

to a directory that you have write access to, you shouldn’t need to run as root.

I got it to work. Thanks. It was indeed related to $PDK_ROOT. What I had to do to fix it was to first install "volare" manually (maybe it was already installed, but I went through the process on the GitHub anyway). Next I changed my PDK_ROOT to ~/.volare. Then, when I ran the "make" step, it successfully downloaded the needed version of the PDK and placed it into that directory. Then, I had to run a "sudo make clean_runs" to delete the files generated during the previous sudo make test, then I also ran "make clean_results". After this I was able to run "make" then "make test" successfully.
