5 years ago I am also experiencing this issue.
Depending on whether it is a fresh build (i.e. I delete dist and dist-newstyle), I get different failures.
Fresh build:
$ cabal new-repl

ghc: ^^ Could not load '_hw_json_simd_avx2_enabled', dependency unresolved. See top entry above.
ByteCodeLink: can't find label
During interactive linking, GHCi couldn't find the following symbol:
hw_json_simd_avx2_enabled
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 send a bug report to:

I am building a library using FFI. I have a file: FMU.hs with
foreign export ccall setup :: IO ()I have a c file: hfmu.c with all thehs_init()andhs_exit(). It has an include:#include hfmu_stub.h, which contains:extern void setup();It then calls the functionsetupafterhs_init().It works fine when performing
cabal new-build, and an external application can load the library and call thesetupfunction.However, with cabal new-repl I get the following error:
The actual sources are here: https://github.com/hfmu/hfmu
If I comment the setup() function call within hfmu.c, then it works fine.
Any ideas on how to fix it?
