The temptation is to paper over each failure with a wrapper or a binary patch. The discipline is to fix the actual dependency so the package is honest about what it needs.\n\n**Core principle:** Make the package's real dependencies explicit, don't disguise them. A `wrapProgram` that injects a path or a `patchelf` that rewrites an interpreter hides a missing dependency instead of declaring it, and it breaks the next person who builds on your package.\n\n## When to Use\n\n- Packaging Yosys, OpenROAD, a simulator, or a vendor EDA binary in Nix\n- A tool fails at runtime to dlopen a plugin or find a shared library\n- Writing derivations and build phases for hardware tooling\n- Building/evaluating on aarch64-linux\n\n## Don't Reach For The Hacks\n\nThese are the moves to avoid, and what they're hiding:\n\n- **`wrapProgram` to inject `LD_LIBRARY_PATH` / plugin paths.** Hides a real missing runtime dependency. The library belongs in `buildInputs` and on the proper rpath, or the plugin belongs in a declared search path the program already honors.\n- **`patchelf` to rewrite the interpreter or rpath by hand.** Hides a build that didn't link correctly. Fix the link, or for unbuildable prebuilt blobs use the proper mechanism (`autoPatchelfHook`) only as a last resort and only for genuinely closed binaries, not to dodge a dlopen issue in something you build from source.\n- **`autoPatchelfHook` as a dlopen fix.** It patches `NEEDED` entries; it does not solve a runtime `dlopen(\"libfoo.so\")` that searches a path you haven't set up. Reaching for it here means you're treating the wrong layer.\n\nWhen a dlopen fails, find what the tool actually dlopens and at what path, then provide that path the way the tool expects (a real search path, a data dir, an env the program documents) rather than wrapping the binary.\n\n## Build Phases: Strings, Not Shell-Var Helpers\n\nWhen you need a custom build or install phase, write the phase as a build-phase string. Do not try to pass derivation outputs like `$out` through command-line-builder helpers (the `toCommandLineShellGNU`-style functions); `$out` is a shell variable that only exists at build time inside the phase, and threading it through a Nix-level argument builder produces the wrong thing.\n\n```nix\n# Right: $out is referenced inside the phase string, where it exists.\nbuildPhase = ''\n  make PREFIX=$out -j$NIX_BUILD_CORES\n'';\n\n# Wrong: trying to bake $out into a CLI arg list at Nix eval time.\n# $out is not defined then; the helper sees a literal or empty value.\n```\n\n## Platform Awareness\n\n- The dev/build machine is aarch64-linux. Use that platform for `nix eval`/`nix build` and don't assume x86_64 in scripts or test invocations.\n- If a tool genuinely lacks an aarch64 build, that is a real problem to solve (cross, emulation, or upstream fix), not something to mask.\n\n## Red Flags\n\n| Smell | Do instead |\n|-------|------------|\n| `wrapProgram --set LD_LIBRARY_PATH` to fix dlopen | Declare the dep; put the lib on rpath or the documented search path |\n| Hand `patchelf` to fix a from-source build | Fix the link / buildInputs |\n| `autoPatchelfHook` to solve a `dlopen` | Provide the runtime search path the tool expects |\n| Threading `$out` through a CLI-arg helper | Reference `$out` inside the buildPhase string |\n| Assuming x86_64 on the dev box | It's aarch64-linux |\n\n## Midstall House Style\n\n- No packaging hacks: no `wrapProgram`/`patchelf`/`autoPatchelfHook` to paper over dlopen issues. Fix the real dependency.\n- Build phases use buildPhase strings; don't pass `$out` through `toCommandLineShellGNU`-style helpers.\n- aarch64-linux is the dev platform.
