Got error while processing diagnostics (Cannot load -dynamic objects)

[josefdolezal]

I am trying to setup HIE with VS Code on mac OS but whenever I open Haskell file, I got following error:

Got error while processing diagnostics: lib/LensesConfig.hs:1:1: fatal: Cannot load -dynamic objects when GHC is built the normal way To fix this, either: (1) Use -fexternal-interpreter, or (2) Build the program twice: once the normal way, and then with -dynamic using -osuf to set a different object file suffix.

Source: Haskell Language Server (Extension)

I followed the installation instructions in README and built HIE using make hie-8.4.3 (hie and hie-wrapper are in $PATH). The project I am working on is open source (available here: https://github.com/ds-wizard/dsw-server) and builds without errors. Even though the error message is pretty clear I am not sure how to fix it 😞 .

I assumed the problem is caused by VS Code extension, but got the same error with Atom.

Any help is appreciated :-)

I am getting a HIE crash (not GhcMod error) when loading this project

hie-8.4.4 loads this project fine on NixOS.

I just recompiled the project with lts-12.26 resolver with hie-8.4.4 but got same error result. I would like to help out, but I am not even sure how to debug this..

I am not familiar with MacOS but what happens if you remove the -dynamic flag from the ghc-options in *.cabal?

I did:

rm -rf .stack-work
hpack
vim dsw-server.cabal
stack build

but got the same error again :-/
