Nix dependency types

For a summary on how to add dependencies to an EPICS top, read the Dependencies guide.

Important

When declaring dependencies for other Nix packages:

  • Add system library dependencies go into both buildInputs.

  • Add tools required only during the build process to nativeBuildInputs.

  • Other attributes exist for more complex cases

When opening the ioc.nix in the EPNix IOC template, you’ll find several dependency types such as:

  • nativeBuildInputs

  • buildInputs

  • propagatedBuildInputs

These dependency types relate to their roles during cross-compilation and determine whether dependencies should be propagated to dependent packages.
