Introduction

As a developer, you may have encountered the error message [ERROR] External dependency handling not supported for OS family 'guix' when trying to build a project using the opam-monorepo tool. This error can be frustrating, especially when you're trying to use a specific operating system, such as Guix, which is a Linux distribution that provides a unique set of tools and features. In this article, we'll explore the reasons behind this error and provide a step-by-step guide to resolve it.

Understanding the Error Message

The error message [ERROR] External dependency handling not supported for OS family 'guix' indicates that the opam-monorepo tool is not compatible with the Guix operating system. This is because the tool relies on a specific set of dependencies and libraries that are not available on Guix. The error message also suggests that you can disable this check using the opam option --global depext=false command.

Why is opam-monorepo Not Compatible with Guix?

The opam-monorepo tool is designed to work with a specific set of dependencies and libraries that are commonly used in the OCaml ecosystem. However, Guix has its own set of dependencies and libraries that are not compatible with the opam-monorepo tool. This is because Guix is a Linux distribution that provides a unique set of tools and features, and the opam-monorepo tool is not designed to work with these tools and features.

Resolving the Error

To resolve the error, you can try the following steps:

Step 1: Disable the Depext Check

You can disable the depext check using the opam option --global depext=false command. This will allow you to build the project without the depext check.

opam option --global depext=false

Step 2: Update the Opam Switch

You can update the opam switch using the opam switch update command. This will ensure that you have the latest version of the opam switch.

Step 3: Rebuild the Project

You can rebuild the project using the make command. This will allow you to build the project without the depext check.

make

Conclusion

The [ERROR] External dependency handling not supported for OS family 'guix' error can be frustrating, especially when you're trying to use a specific operating system, such as Guix. However, by disabling the depext check and updating the opam switch, you can resolve the error and build the project successfully.
