h Checking out the closure

n The \'closure\' is the full set of all the \(runtime\) dependencies:
x nix path-info -sSrh ./result

x nix build "${dir}#cross-riscv64"

x nix build "${dir}#cross-riscv64" -L

h Static executables
, We can also cross compile a static build:
x nix build "${dir}#static" -L
, And this is indeed a static binary:
x "${file_cmd}" ./result/bin/wttr-delft
x ls -lh ./result/bin/wttr-delft
h Everything together
, Static cross compiled for aarch64-linux - you can copy this executable and run it on a Raspberry Pi!
x nix build "${dir}#cross-aarch64-static" -L
x "${file_cmd}" ./result/bin/wttr-delft
x ls -lh ./result/bin/wttr-delft

p

, And we can actually run it as well!
x ./result/bin/wttr-delft
