+#### Problems with dynamic linking
+
+As haskell-language-server prebuilt binaries are statically linked, they don't play well with projects using dynamic linking.
+An usual symptom is the presence of errors containing `unknown symbol` and it is typical in arch linux, where a dynamically linked version of ghc is used. 
+
+The workaround is to use a version of haskell-language-server compiled from source with `-dynamic` enabled`. See more details [here](https://github.com/haskell/haskell-language-server/issues/1160#issuecomment-756566273).
