# How to install the optional LAMMPS package DPD-REACT in MacOS?

I have installed LAMMPS on my mac-pro (OS Monetery), using this.

I installed Homebrew and then LAMMPS. I need to install DPD-REACT package. I tried -D PKG_DPD-REACT=on in my terminal following this, but it said command not found: -D .

I also tried the make command, and got: make yes-DPD-REACT make: *** No rule to make target yes-DPD-REACT'. Stop.

I am not sure how to install my DPD-REACT package. Can anybody help me with that please?

• Delaram, did you figure this out? Please update us! Is it just LAMMPS that you want to install on MacOS? The title just says "a package" which is very vague. Dec 10, 2022 at 16:09
