  1. # Nix package for GNUnet development
  2. #
  3. ## INSTALL
  4. #
  5. # To build and install the package in the user environment, use:
  6. #
  7. # $ nix-env -f . -i
  8. #
  9. ## BUILD ONLY
  10. #
  11. # To build the package and add it to the nix store, use:
  12. #
  13. # $ nix-build
  14. #
  15. ## SHELL
  16. #
  17. # To launch a shell with all dependencies installed in the environment, use one of the following:
  18. # $ nix-shell
  19. #
  20. # After entering nix-shell, build it:
  21. #
  22. # $ configurePhase
  23. # $ buildPhase
  24. #
  25. ## NIXPKGS
  26. #
  27. # For all of the above commands, nixpkgs to use can be set the following way:
  28. #
  29. # a) by default it uses nixpkgs pinned to a known working version
  30. #
  31. # b) use nixpkgs from the system:
  32. # --arg pkgs 0
  33. #
  34. # c) use nixpkgs at a given path
  35. # --arg pkgs /path/to/nixpkgs
  36. #
  37. ## CCACHE
  38. #
  39. # To enable ccache, use the following:
  40. #
  41. # --argstr ccache_dir /var/cache/ccache
  42. # or when using nix-shell:
  43. # --argstr ccache_dir ~/.ccache
  44. #
  45. # and make sure the given directory is writable by the nixpkgs group when using nix-build or nix-env -i,
  46. # or the current user when using nix-shell
  47. #
