 Daniel Firth | Occasionally dropping a new horizon expression as a separate package set expression into nixpkgs, one that didn't interfere with haskellPackages proper, would be quite easy for me to automate, it just depends whether that's OK or not. | 12:08:34 |

 alexfmpe | when using pkgsStatic on my aarch64-darwin, most packages correctly build only the .o
$ nix-build -A pkgsStatic.haskell.packages.ghc910.these
Building library for these-1.2.1...
[1 of 3] Compiling Data.Functor.These ( src/Data/Functor/These.hs, dist/build/Data/Functor/These.o )
however there's a few odd ones where .dyn_o is also attempted
$ nix-build -A pkgsStatic.haskell.packages.ghc910.deferred-folds
Building library for deferred-folds-0.9.18.7...
[ 1 of 11] Compiling DeferredFolds.Prelude ( library/DeferredFolds/Prelude.hs, dist/build/DeferredFolds/Prelude.o, dist/build/DeferredFolds/Prelude.dyn_o )
$ nix-build -A pkgsStatic.haskell.packages.ghc910.constraints-extras
Building library for constraints-extras-0.4.0.2..
[1 of 4] Compiling Data.Constraint.Compose ( src/Data/Constraint/Compose.hs, dist/build/Data/Constraint/Compose.o, dist/build/Data/Constraint/Compose.dyn_o )
$ nix-build -A pkgsStatic.haskell.packages.ghc910.language-nix
Building library for language-nix-2.3.0...
[1 of 4] Compiling Language.Nix.Identifier ( src/Language/Nix/Identifier.hs, dist/build/Language/Nix/Identifier.o, dist/build/Language/Nix/Identifier.dyn_o )
unsurprisingly, these all fail with Failed to load dynamic interface file for <import>
| 01:25:46 |
| alexfmpe | but where are these random .dyn_o coming from? | 01:26:03 |
| alexfmpe | we're passing both
--disable-shared
--disable-executable-dynamic
| 01:27:58 |
| alexfmpe | these / language-nix got pretty much the same configureFlags, save for the package-db | 01:39:34 |
| alexfmpe | diff these.flags language-nix.flags

| alexfmpe | curiously I can trigger the same by enabling haddocks for pkgsStatic, but for a different set of packages | 02:02:00 |

| alexfmpe | I've noticed iserv-proxy is getting built for ghcjs even though it's not actually used
is it worth adding a && !isGhcjs to the "should we proxy TH" to save builds of network->iserv-wrapper ? | 19:31:21 |
