opam: required argument PACKAGES is missing about iec-checker HOT 5 CLOSED

Hi @humazahid332,

The first command opam install --deps-only . successfully finished. It says that you already have all the required packages.

Next, when you execute opam install --deps-only (without dot .), opam asks you to provide package you want to install. This command is incorrect, you don't need it.

So you can continue to build the package with dune according to the README.

How to install the IEC checker now. I am executing the next command in the readme but it gives an error.

cd to the project directory.

Well, I understood. You didn't clone the repository.

OK, when you're building a project from the source code, first you need to get the sources, right? So, execute the following command:

git clone https://github.com/jubnzv/iec-checker

This command downloads the source code of iec-checker to your machine using git. Then you should cd to the downloaded directory:

cd iec-checker

And then you should just execute commands from the README file:

opam install --deps-only .
dune build @install
mkdir output
dune install --prefix ./output

Please note that these are things that every developer should know. I suggest you to read the Git book and some introduction to the unix-like systems.

Also, if building from the source code is hard, feel free to download pre-built binaries from the release page: https://github.com/jubnzv/iec-checker/releases/tag/v0.4.

I close this, since I think that the issue is solved. Feel free to re-open it, if you have any other questions.
