packages

Packages which are not created by the redistributable builder.

Conventions

• All new packages should include the following lines as part of their arguments to stdenv.mkDerivation:

  finalAttrs: {
    __structuredAttrs = true;
    strictDeps = true;
  
    # NOTE: Depends on the CUDA package set, so use cudaNamePrefix.
    name = "${cudaNamePrefix}-${finalAttrs.pname}-${finalAttrs.version}";
  }
  

  If the package does not require elements of the package set, then the cudaNamePrefix must be omitted: changing the name of a derivation yields a different hash and store path, so we would end up with multiple different store paths with the same content.
