#### examples of use: ####
|
|
|
|
# Add this to your ~/.nixpkgs/config.nix:
|
|
|
|
{
|
2012-03-14 23:38:28 +00:00
|
|
|
packageOverrides = pkgs : with pkgs; {

|
|
}
|
|
|

|
2012-03-20 14:51:18 +00:00
|
|
|
# Then you can install it by:
|
2013-02-23 11:32:15 +00:00
|
|
|
# $ nix-env -i env-sdl
|
2012-03-20 14:51:18 +00:00
|
|
|
# And you can load it simply calling:
|
2012-03-26 11:20:32 +01:00
|
|
|
# $ load-env-sdl
|
2012-03-14 23:07:59 +00:00
|
|
|
# and this will update your env vars to have 'make' and 'gcc' finding the SDL
|
|
|
|
# headers and libs.

# Make an environment to build nix from source and create ctags (tagfiles can
|
|
|
|
# be extracted from TAG_FILES) from every source package. Here would be a

# full ~/.nixpkgs/config.nix
