Statically linking Haskell executables (Linux)

From Carter T Schonwald (@cartazio)

  • Build the binary
  • > ldd binary
  • Copy listed .sos into a subdirectory next to the binary
  • Set the load library path environment var to point to that relative or absolute dir

Note: Subject to having compatible glibc ABI between host and target Linux
