Is it possible to generate a static binary of OpenROAD?

[TiagoAFontana]

Hi all, I am trying to execute the OpenROAD in a cluster machine. However, in this machine, I am not able to install the dependencies to compile the OpenROAD or even use the docker image to run the OpenROAD.

I was wondering if it is possible to set a cmake flag to generate a static binary (without any dependencies) for the OpenROAD project. With this, I will be able to run this binary on every machine that I need.

Does someone know how to do this?

@vvbandeira Any suggestion?

I do not think we support this at the moment, but you can certainly try to compile only with static libraries. A suggestion would be to first disable optional features like Python and GUI support (-DBUILD_PYTHON=OFF -DENABLE_GUI=OFF), since you are running on a cluster I think this should be fine. This would likely make it easier.

Another alternative you could try is to use a program like guix or conda that do not require root to install packages. Then you can use them to install the OpenROAD dependencies.

Bazel rules hdl supports fully static builds of openroad.

Just download bazel, git clone https://github.com/hdl/bazel_rules_hdl

And run bazel build @org_theopenroadproject//:openroad in the git repo.

It also statically builds the entire dependency chain of openroad from source.
