#286 Cannot run ./configure -- either saying "Illegal variable name" or "No match" New issue created by ChrisZonghaoLi Error statement Hello, So I was trying to run the "./configure" file for setting up the PDK installation (which I was following the README.md instructions). I am - using Debian GNU/Linux 10 (buster) with Linux 4.19.0-20-amd64 as the kernal. Also I am using tcsh. Reproduce the error I have already downloaded the sky130 PDK separately in the directory <$HOME$/skywater-pdk>, which means when running the ./configure file I have to also specify the directory of the PDK. The entry is now: ./configure --enable-sky130-pdk[=$HOME/skywater-pdk], and the following result shown: This is the script of ("which I have changed to tcsh") Thanks! Chris RTimothyEdwards/open_pdks
