OS: Ubuntu 20.04.03 Docker version 20.10.21, build baeda1f Steps Followed:

git clone https://github.com/VLSIDA/OpenRAM
cd OpenRAM/docker
make build

The error:

If I edit the docker file and add --reject --whitespace=fix to the git command. The error evolves into this:

The solution is to apply dos2unix to all files before compiling.

find /path -type f -print0 | xargs -0 dos2unix --

Nope. The line endings were correct in the repo. My git preferences were wonky. Git automatically converts line endings if autocrlf = true is set in preferences. That was the case for me. Changing my gitpereferences fixed it.

[core]
    autocrlf = false
    eol = lf
