addDLL: stdc++ or dependencies not loaded. (Win32 error 126)
Summary
GHC 9.4.4 causes below error when compiling the code which depend on both file-embed
and proteaaudio
package on Windows, while GHC 8.10.7 does not.
<no location info>: error:
addDLL: stdc++ or dependencies not loaded. (Win32 error 126)
Individually, these packages can be compiled and executed with no problem.
Especially, generated sample executable for proteaaudio
runs fine.
However, when both file-embed
and proteaaudio
are added to build-depends field of .cabal file, below trivial code does not compile with above error:
{-# LANGUAGE TemplateHaskell #-}
module Main where
import Data.FileEmbed
import Data.ByteString (ByteString)
main :: IO ()
main = putStrLn "Hello World!"
buffer :: ByteString -- not used
buffer = $(embedFile "data/mm2_1401.wav")
Steps to reproduce
% git clone https://github.com/wkoiking/proteaaudio-test.git
% cd proteaaudio-test
% stack build
When the code depends only on proteaaudio
, the error does not occur.
Which can be checked by:
% git checkout 765abc2
% stack run
Expected behavior
The compilation should succeed without error.
