GHC.Linker.Loader.dynLoadObjs: Loading temp shared object failed
During interactive linking, GHCi couldn't find the following symbol:
  dlopen(/tmp/nix-shell.aWYMbw/ghc56626_0/libghc_2.dylib, 0x0009): symbol not found in flat namespace '_A_dep_closure'
This may be due to you not asking GHCi to load extra object files,
archives or DLLs needed by your current session.  Restart GHCi, specifying
the missing library using the -L/path/to/object/dir and -lmissinglibname
flags, or simply by naming the relevant files on the GHCi command line.
Alternatively, this link failure might indicate a bug in GHCi.
If you suspect the latter, please report this as a GHC bug:
  https://www.haskell.org/ghc/reportabug

Failed, two modules loaded.

A.hs

module A where

dep :: IO ()
dep = putStrLn "dep."

B.hs

{-# LANGUAGE TemplateHaskell #-}
{-# OPTIONS_GHC -ddump-splices #-}
 
module B (test) where

import TH (th)

test :: IO ()
test = do
  let s = $(th ''Double)
  print (s :: Maybe String)

TH.hs

{-# LANGUAGE TemplateHaskell #-}
module TH (th) where

import A
import Control.Monad.IO.Class (liftIO)

th n = do
  liftIO dep
  [|Nothing|]

if I change both TH and A, then it's okay as all the modules are interpreted.
