Usage: nix-build [OPTION]... [FILE]...
|
|
|
|
`nix-build' builds the given Nix expressions (which
|
|
default to ./default.nix if none are given). A symlink called
|
|
`result' is placed in the current directory.
|
|
|
|
Flags:
|
|
--add-drv-link: create a symlink `derivation' to the store derivation
|
|
--drv-link NAME: create symlink NAME instead of `derivation'
|
|
--no-out-link: do not create the `result' symlink
|
|
--out-link / -o NAME: create symlink NAME instead of `result'
|
|
--attr ATTR: select a specific attribution from the Nix expression
|
|
|
|
Any additional flags are passed to `nix-store'.
