- I worked on linux and macos without any
cabalproblems at all. - When I moved to windows I can't link even the simplest application:
> cabal --version
cabal-install version 3.10.2.0
compiled using version 3.10.2.1 of the Cabal library
> ghc --version
The Glorious Glasgow Haskell Compilation System, version 9.8.1
Here is my cabal file:
cabal-version: 3.0
name: dummy
version: 0.1.0.0
common warnings
ghc-options: -Wall
executable dummy
main-is: Main.hs
other-modules: Token,
Location
build-depends: base ^>=4.19.0.0,
aeson
hs-source-dirs: app
default-language: GHC2021
And here is the error I get:
[1 of 3] Compiling Location ( ... omitted ... )

[3 of 3] Compiling Token ( ... omitted ... )

I tried adding various flags for cabal build (though none were needed on macos and linux):
--enable-executable-static(didn't work)--disable-executable-dynamic(didn't work)--enable-static(didn't work)--disable-shared(you guessed it, didn't work)
I'm pretty sure the actual source files don't matter, but let me know in the comments if they are needed.
