Getting can't load .so/.DLL for libHSrandom

[cah6]

Hey all,

This is on OSX, with an dev environment provided by Nix. Note that for this dev environment, we have library haddocks and profiling enabled. I'm using GHC 8.6.4 with HIE provided by all-hies with (all-hies.selection { selector = p: { inherit (p) ghc864; }; }). The issue I'm running into when loading HIE up in VSCode is:

<command line>: can't load .so/.DLL for: /nix/store/yb297ih6bbk45dl608blp6m22jv86n7w-ghc-8.6.4-with-packages/lib/links/libHSrandom-1.1-3ypV4EIycgb35PKjTYYr5q-ghc8.6.4.dylib (dlopen(/nix/store/yb297ih6bbk45dl608blp6m22jv86n7w-ghc-8.6.4-with-packages/lib/links/libHSrandom-1.1-3ypV4EIycgb35PKjTYYr5q-ghc8.6.4.dylib, 5): Symbol not found: _timezm1zi8zi0zi2_DataziTimeziClockziInternalziCTimespec_zdwclockGetTime_closure

which seems pretty similar to #1207. I have seen https://github.com/haskell/haskell-ide-engine#dyld-on-macos but am unsure if that's the issue or how to fix it if it is (adding that export doesn't fix it).

Based off the comments in #1207, I am wondering: if I have haddocks/profiling enabled for my libaries, do I need to build HIE with haddocks/profiling enabled too? If yes, I'm assuming this would not be provided by all-hies and I would have to do a custom build from source. I'm not sure how to do this via nix (would love pointers), but would it theoretically work if I built with stack with the correct options enabled and used that in my nix project?

got a similar issue on nixos.
