This seems like *a lot* of code to make a static build. I don't understand how to add arbitrary hackage binaries or how to use a more recent version of GHC.#haskell #nixhttps://github.com/lunaris/minirepo

@hyperrealgopher That does look a bit tricky. I've never tried to build using Bazel _and_ Nix or to produce a static Haskell binary. But I know a little Nix. To me it looks like this is where the GHC version is selected: https://github.com/lunaris/minirepo/blob/58c3a67a09e97d22995380bb97f9e8cef6215fa9/nix/haskell/default.nix#L77, it's using the default version of the compiler from the static Haskell reference here: https://github.com/lunaris/minirepo/blob/58c3a67a09e97d22995380bb97f9e8cef6215fa9/nix/haskell/default.nix#L34. It looks like in the pinned version as well as master that GHC is at 8.6.4 (https://github.com/nh2/static-haskell-nix/blob/dbce18f4808d27f6a51ce31585078b49c86bd2b5/default.nix#L3, https://github.com/nh2/static-haskell-nix/blob/382150290ba43b6eb41981c1ab3b32aa31798140/default.nix#L3).

@hyperrealgopher Oops my bad, they import a sub-path of that static Haskell repo: https://github.com/lunaris/minirepo/blob/58c3a67a09e97d22995380bb97f9e8cef6215fa9/nix/haskell/default.nix#L42. Looks like that function accepts arguments to change the GHC version: https://github.com/nh2/static-haskell-nix/blob/382150290ba43b6eb41981c1ab3b32aa31798140/survey/default.nix#L37-L48 ... looks like they except that to be called with 8.8.1 as the newest possible version ("ghc881").

@hyperrealgopher Hrm, and as for arbitrary binaries ... there isn't a `default.nix` or `release.nix` I guess because you only need the Nix environment to build a fully static binary ... so that makes sense I suppose. If you want extra stuff in that build environment that can be included in the result I guess you might add it here: https://github.com/lunaris/minirepo/blob/58c3a67a09e97d22995380bb97f9e8cef6215fa9/nix/shell.nix#L47-L59

@brad Thank you for all this effort! I would've been lost otherwise. I was wondering about regular cabal library dependencies that may not be on stackage like ConfigFile.

@hyperrealgopher Sorry, that looks like it's handled with Bazel (https://github.com/lunaris/minirepo/blob/58c3a67a09e97d22995380bb97f9e8cef6215fa9/example-service/BUILD.bazel#L34-L38)? I'm not sure I'll be of any help there, hope you have better luck with it all soon!
